To order <strong>HP</strong> supplies, visit http://www.hp.com.When select<strong>in</strong>g labels, consider the quality of the follow<strong>in</strong>g factors:● Adhesives: The adhesive material should be stable at 200° C (392° F), the productsmaximum temperature.● Arrangement: Use only labels that have no exposed back<strong>in</strong>g between them. Labels canpeel off sheets that have spaces between the labels, caus<strong>in</strong>g serious jams.● Curl: Before pr<strong>in</strong>t<strong>in</strong>g, labels must lie flat with no more than 13 mm (0.5 <strong>in</strong>ch) of curl <strong>in</strong> anydirection.● Condition: Do not use labels that have wr<strong>in</strong>kles, bubbles, or other <strong>in</strong>dications ofseparation. Never use a sheet of labels that has already been run through the device.EnvelopesWhen select<strong>in</strong>g envelopes, consider the quality of the follow<strong>in</strong>g factors.Envelope constructionEnvelope construction is critical. Envelope fold l<strong>in</strong>es can vary considerably, not only betweenmanufacturers, but also with<strong>in</strong> a box from the same manufacturer. Successful pr<strong>in</strong>t<strong>in</strong>g <strong>one</strong>nvelopes depends on the quality of the envelopes, which <strong>in</strong>cludes the follow<strong>in</strong>g factors:●●●●Weight: The weight of the envelope paper should not exceed 105 g/m 2 (28 lb), or jamm<strong>in</strong>gmight result.Construction: Before pr<strong>in</strong>t<strong>in</strong>g, envelopes should lie flat with less than 6 mm (0.25 <strong>in</strong>ch)curl and should not conta<strong>in</strong> air. Envelopes that trap air might cause problems.Condition: Make sure that the envelopes are not wr<strong>in</strong>kled, nicked, or otherwisedamaged.Sizes: Supported envelope sizes range from 90 by 160 mm (3.5 by 6.3 <strong>in</strong>ches) to 178 by254 mm (7 by 10 <strong>in</strong>ches).40 Chapter 2 Operation ENWW
Envelopes with double-side seamsAn envelope with double-side-seam construction has vertical seams at both ends of theenvelope rather than diagonal seams. This style is more likely to wr<strong>in</strong>kle dur<strong>in</strong>g pr<strong>in</strong>t<strong>in</strong>g. Makesure that the seam extends <strong>all</strong> the way to the corner of the envelope as shown <strong>in</strong> the follow<strong>in</strong>gillustration:Figure 2-6.Envelope constructionEnvelopes with adhesive strips or flapsEnvelopes with a peel-off adhesive strip or with more than <strong>one</strong> flap that folds over to sealmust use adhesives that are compatible with the heat and pressure <strong>in</strong> the device (200° C or392° F). The extra flaps and strips might cause wr<strong>in</strong>kl<strong>in</strong>g, creas<strong>in</strong>g, or jams.Envelope storageProper storage of envelopes contributes to good pr<strong>in</strong>t quality. Store envelopes flat to ensuregood pr<strong>in</strong>t quality. If air is trapped <strong>in</strong> an envelope, creat<strong>in</strong>g an air bubble, the envelope mightwr<strong>in</strong>kle dur<strong>in</strong>g pr<strong>in</strong>t<strong>in</strong>g.Card stock and heavy mediaSome card stock performs better than others because the construction is better suited forfeed<strong>in</strong>g through a laser device. For optimum device performance, do not use media heavierthan 157 g/m 2 (42 lb). Media that is too heavy might cause misfeeds, stack<strong>in</strong>g problems,media jams, poor t<strong>one</strong>r fus<strong>in</strong>g, poor pr<strong>in</strong>t quality, or excessive mechanical wear.NoteYou might be able to pr<strong>in</strong>t on heavier media if you do not fill the <strong>in</strong>put trays to capacity and ifyou use media with a smoothness rat<strong>in</strong>g of 100 to 180 Sheffield.Card stock construction●●Smoothness: 135 to 157 g/m 2 (36 to 42 lb) card stock should have a smoothness rat<strong>in</strong>gof 100 to 180 Sheffield. 60 to 135 g/m 2 (16 to 36 lb) card stock should have a smoothnessrat<strong>in</strong>g of 100 to 250 Sheffield.Construction: Card stock should lie flat with less than 5 mm (0.2 <strong>in</strong>ch) of curl.ENWW Guidel<strong>in</strong>es for us<strong>in</strong>g media 41

The ECUsynchronizes the image-formation system with the paper-feed system and signals theformatter to send the pr<strong>in</strong>t-image data. The formatter sends the pr<strong>in</strong>t-image data (dots) <strong>in</strong> theform of a video signal, and the pr<strong>in</strong>t<strong>in</strong>g process beg<strong>in</strong>s.Central process<strong>in</strong>g unitThe formatter <strong>in</strong>corporates an embedded Coldfire V4 processor operat<strong>in</strong>g at 133 MHz.L<strong>in</strong>e <strong>in</strong>terface unit (<strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> and <strong>3030</strong> only)The l<strong>in</strong>e <strong>in</strong>terface unit (LIU) provides the required safety isolation, signal coupl<strong>in</strong>g, andimpedance match<strong>in</strong>g between the teleph<strong>one</strong> l<strong>in</strong>e and the modem chipset that is located on theformatter.Standard boot processWhen the product is unplugged or the power is off, the firmware code is stored on theformatter <strong>in</strong> two blocks. The first block of code is an executable boot block (about 64 K ofcode). The second block of code is a compressed version of the product control code.When the product is turned on, the boot block decompresses the product control code andstores it <strong>in</strong> RAM. Then the product performs a full startup with the control code runn<strong>in</strong>g fromRAM.Product startup messagesThe LED display conta<strong>in</strong>s different messages depend<strong>in</strong>g upon the progress of the bootprocess:ENWW Formatter system 75

NoteWhen us<strong>in</strong>g EconoMode image quality (both clarity and contrast) will be considerablydecreased because less t<strong>one</strong>r is applied to the page.MEt<strong>HP</strong> Memory Enhancement technology (MEt) effectively doubles the standard memory througha variety of font- and data-compression methods.Enhanced I/OThe enhanced I/O (EIO) feature <strong>all</strong>ows product memory to be used for stor<strong>in</strong>g data receivedfrom the host computer. When EIO is enabled, you can send more data to the product <strong>in</strong>shorter amounts of time, so that you can return to the software program more quickly. The EIOfeature has the follow<strong>in</strong>g options:●●Auto —the product uses EIO memory <strong>all</strong>ocation to <strong>in</strong>crease the speed of data transferfrom the host computer to the product, if necessary. The default sett<strong>in</strong>g is Auto.Off —the m<strong>in</strong>imum amount of product memory is used to store data that is sent from thehost computer.● Page Protect—the formatter creates the entire page image <strong>in</strong> page-buffer memory beforephysic<strong>all</strong>y mov<strong>in</strong>g the media through the pr<strong>in</strong>ter. This process ensures that the entire pagewill be pr<strong>in</strong>ted.Page complexity (rul<strong>in</strong>g l<strong>in</strong>es, complex graphics, or dense text) can exceed the pr<strong>in</strong>ter’s abilityto create the page image fast enough to keep pace with the image-formation process. If PageProtect is disabled and a page is too complex, the page might pr<strong>in</strong>t <strong>in</strong> sections (for example,the top half on <strong>one</strong> page and the bottom half on the next page). Some pr<strong>in</strong>t-data loss is likely<strong>in</strong> these <strong>in</strong>stances, and an error message will appear on the control-panel display.PJL overviewPr<strong>in</strong>ter job language (PJL) is an <strong>in</strong>tegral part of configuration, <strong>in</strong> addition to the standardpr<strong>in</strong>ter command language (PCL). With standard ECP cabl<strong>in</strong>g, the product can use PJL toperform the follow<strong>in</strong>g functions:●●Two-way communication with the host computer through a bidirectional par<strong>all</strong>elconnection.

Image-formation systemLaser pr<strong>in</strong>t<strong>in</strong>g requires the <strong>in</strong>teraction of several different technologies <strong>in</strong>clud<strong>in</strong>g electronics,optics, and electrophotographics to provide a pr<strong>in</strong>ted page. Each process functions<strong>in</strong>dependently and must be coord<strong>in</strong>ated with the other pr<strong>in</strong>ter processes. Image formationconsists of seven processes:Writ<strong>in</strong>g StageFlow of paperDirection of drum rotation2. Scann<strong>in</strong>g exposure1. Primary charg<strong>in</strong>g3. Develop<strong>in</strong>g stageDrum clean<strong>in</strong>gstage7. Drum clean<strong>in</strong>gPaper deliveryFus<strong>in</strong>g stage5. Separation 4. TransferPickup6. Fus<strong>in</strong>gTransfer stageFigure 4-6.Image-formation block diagramThe seven image-formation processes1. Condition<strong>in</strong>g stage (primary charg<strong>in</strong>g)—This process applies a uniform negativecharge to the surface of the drum with the primary charg<strong>in</strong>g roller, which is located <strong>in</strong> thepr<strong>in</strong>t cartridge. The primary charg<strong>in</strong>g roller is coated with conductive rubber. An ac bias isapplied to the roller to erase any residual charges from any previous image. In addition,the primary charg<strong>in</strong>g roller applies a negative dc bias to create a uniform negativepotential on the drum surface. The pr<strong>in</strong>t density sett<strong>in</strong>g modifies the dc voltage.2. Writ<strong>in</strong>g stage (scann<strong>in</strong>g exposure)—Dur<strong>in</strong>g this process, a modulated laser diodeprojects the beam onto a rotat<strong>in</strong>g scann<strong>in</strong>g mirror. As the mirror rotates, the beam reflectsoff the mirror, first through a set of focus<strong>in</strong>g lenses, then off a mirror, and f<strong>in</strong><strong>all</strong>y through aslot <strong>in</strong> the top of the pr<strong>in</strong>t cartridge, and onto the photosensitive drum. The beam sweepsthe drum from left to right, discharg<strong>in</strong>g the negative potential wherever the beam strikesthe surface. This creates a latent electrostatic image, which later is developed <strong>in</strong>to avisible image. Because the beam sweeps the entire length of the drum while the drumrotates, the entire surface area of the drum can be covered. At the end of each sweep, thebeam strikes the beam-detect lens, generat<strong>in</strong>g the beam-detect signal (BD signal). The BDsignal is sent to the ECU where it is converted to an electrical signal used to synchronizethe output of the next scan l<strong>in</strong>e of data.3. Develop<strong>in</strong>g stage—Dur<strong>in</strong>g this process, the latent electrostatic image is present on thedrum. The t<strong>one</strong>r particles obta<strong>in</strong> a negative surface charge by rubb<strong>in</strong>g aga<strong>in</strong>st thedevelop<strong>in</strong>g cyl<strong>in</strong>der, which is connected to a negative dc supply. The negatively chargedt<strong>one</strong>r is attracted to the discharged (exposed, grounded) areas of the drum, and it isrepelled from the negatively charged (unexposed) areas.4. Transfer stage—Dur<strong>in</strong>g this process, the t<strong>one</strong>r image on the drum surface is transferredto the media. The transfer roller applies a positive charge to the back of the media, whichattracts the negatively charged t<strong>one</strong>r on the drum surface to the media. After separation,the drum is cleaned and conditi<strong>one</strong>d for the next image.5. Separation stage—Dur<strong>in</strong>g this process, the media separates from the drum. To stabilizethe feed system and prevent t<strong>one</strong>r dropouts on the pr<strong>in</strong>ted image at low temperature andhumidity, the static elim<strong>in</strong>ator reduces the charge on the back of the media.ENWW Pr<strong>in</strong>ter functions (<strong>all</strong> models) 83
6. Fus<strong>in</strong>g stage—Dur<strong>in</strong>g this process, the heat and pressure fuse the t<strong>one</strong>r <strong>in</strong>to the mediato produce a permanent image. The media passes between a heated fus<strong>in</strong>g element and asoft pressure roller, which melt the t<strong>one</strong>r and press it <strong>in</strong>to the media.7. Drum-clean<strong>in</strong>g stage—Dur<strong>in</strong>g this process, the clean<strong>in</strong>g blade is <strong>in</strong> contact with thesurface of the drum at <strong>all</strong> times. As the drum rotates dur<strong>in</strong>g pr<strong>in</strong>t<strong>in</strong>g, the clean<strong>in</strong>g bladewipes excess t<strong>one</strong>r off the drum and stores it <strong>in</strong> the waste t<strong>one</strong>r receptacle.Pr<strong>in</strong>t cartridgeAs the focal po<strong>in</strong>t of the image-formation system, the pr<strong>in</strong>t cartridge conta<strong>in</strong>s t<strong>one</strong>r and housesthe clean<strong>in</strong>g, condition<strong>in</strong>g, and develop<strong>in</strong>g stages of the process. The pr<strong>in</strong>t cartridge conta<strong>in</strong>sthe photosensitive drum, primary charg<strong>in</strong>g roller, develop<strong>in</strong>g station, t<strong>one</strong>r cavity, and clean<strong>in</strong>gstation. By <strong>in</strong>clud<strong>in</strong>g these comp<strong>one</strong>nts (which wear, degrade, or are consumed) <strong>in</strong> thereplaceable pr<strong>in</strong>t cartridge, the need for many service c<strong>all</strong>s is elim<strong>in</strong>ated. The specialphotosensitive properties of the drum form an image on the drum surface and then transfer theimage to media.CAUTIONThe pr<strong>in</strong>t cartridge does not <strong>in</strong>clude a light-block<strong>in</strong>g shutter. Do not expose the drum to light,which can permanently damage the drum. Protect the pr<strong>in</strong>t cartridge whenever you remove itby cover<strong>in</strong>g it with paper.Pr<strong>in</strong>ter paper-feed systemThe ma<strong>in</strong> <strong>in</strong>put tray and the priority <strong>in</strong>put tray merge <strong>in</strong>to <strong>one</strong> ma<strong>in</strong> <strong>in</strong>put area. The pr<strong>in</strong>ter usesthe top-of-page sensor (PS801) to senses the paper as it enters the paper feed path. It doesnot sense the presence of media before beg<strong>in</strong>n<strong>in</strong>g the pr<strong>in</strong>t cycle. The follow<strong>in</strong>g steps occurwhen the product receives a pr<strong>in</strong>t job:Step 1Step 2Step 3Step 4Step 5The ECU activates the motor (M1). Paper motionbeg<strong>in</strong>s when the ECU energizes the pick-upsolenoid (SL1).The paper-pickup roller rotates once. The paperliftplate pushes the media aga<strong>in</strong>st the pickuproller.The friction of the pickup roller grabs the top sheetand advances it to the feed-assembly driverollers. To ensure that only <strong>one</strong> sheet is fed, ama<strong>in</strong> separation pad holds the rema<strong>in</strong>der of thestack <strong>in</strong> place.The feed-assembly drive rollers advance themedia to the top-of-page sensor (PS801). Thissensor <strong>in</strong>forms the ECU of the exact location ofthe lead<strong>in</strong>g edge of media, so that the image be<strong>in</strong>gwritten on the photosensitive drum can beprecisely positi<strong>one</strong>d on the page.The feed assembly drive rollers then advance themedia to the transfer area where the t<strong>one</strong>r imageon the photosensitive drum is transferred to themedia.84 Chapter 4 Operational overview ENWW
Step 6Step 7After the image is transferred, the media entersthe fuser assembly where heat from the fuser andpressure from the pressure roller permanentlybond the t<strong>one</strong>r image to media. The paperdeliverysensor (PS803) determ<strong>in</strong>es that themedia has successfully moved out of the fus<strong>in</strong>garea.The fuser-assembly exit rollers deliver media tothe output b<strong>in</strong> face-down.Figure 4-7.Pr<strong>in</strong>ter paper pathJam detection <strong>in</strong> the pr<strong>in</strong>terThe top-of-page sensor (PS801) and the paper-delivery sensor (PS803) detect media mov<strong>in</strong>gthrough the pr<strong>in</strong>ter.

Figure 4-8. Basic operation block diagram shows therelationship of the two systems.Figure 4-8.Basic operation block diagramA document is placed <strong>in</strong>to the ADF tray. When the formatter sends a signal to the opticalscann<strong>in</strong>g system, the document is picked up and fed <strong>in</strong>to the optical system through a seriesof rollers and a separation pad (the separation pad prevents the pickup system from feed<strong>in</strong>gmultiple pages if more than <strong>one</strong> page is loaded <strong>in</strong> the ADF tray).ENWW <strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong> unique comp<strong>one</strong>nts 87
As the document passes the contact image scanner, the scanner illum<strong>in</strong>ates the document.The optical scann<strong>in</strong>g system captures and amplifies the reflected light and converts it to adigital signal, and then sends the digital signal to the formatter for image-process<strong>in</strong>g.Figure 4-9.<strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> optical and feed systems1 Optical scann<strong>in</strong>g system2 ADF pickup and feed systemADF pickup and feed systemThe ADF pickup and feed system uses a pickup roller, a feed roller, and a delivery roller totransport the document <strong>in</strong>to, through, and out of the optical scann<strong>in</strong>g system. The opticalscann<strong>in</strong>g system motor drives the rollers when the formatter signals the optical scann<strong>in</strong>gsystem that a job to pr<strong>in</strong>t or copy is present.There are two sensors along the ADF pickup and feed paper path. The document sensor(PS1201) detects the presence of a document <strong>in</strong> the ADF <strong>in</strong>put tray. The document-topsensor (PS 1202) detects the document <strong>in</strong> the ADF paper path. The formatter processes thesignals from the sensors and the product operates accord<strong>in</strong>gly.88 Chapter 4 Operational overview ENWW
When the contact image scanner motor rotates, it causes the pickup, feed, and delivery rollersto rotate. The ADF document pickup roller pushes a document <strong>in</strong>to the ADF paper path. Theseparation pad prevents multiple pages from enter<strong>in</strong>g the ADF paper path by creat<strong>in</strong>g frictionaga<strong>in</strong>st the document and the pickup roller. The document feed roller advances the documentpast the contact image sensor (CIS). The document delivery roller advances the documentout of the ADF paper path to the output area.Figure 4-10. <strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> feed control (1 of 2)ENWW <strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong> unique comp<strong>one</strong>nts 89
The contact image scanner motor drives the pickup roller, the feed roller, a <strong>one</strong>-way clutch,and the delivery roller. A gear differential causes the pickup roller to rotate at a slower speedthan the feed roller. The slower speed <strong>all</strong>ows for a consistent space between pages of amultiple-page document, which is necessary for correct document scann<strong>in</strong>g. The <strong>one</strong>-wayclutch varies the rotation speeds of the pickup roller and feed roller to prevent the rollers fromtear<strong>in</strong>g the document.Figure 4-11. <strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> feed control (2 of 2)90 Chapter 4 Operational overview ENWW
Optical scann<strong>in</strong>g systemThe contact image sensor (CIS) is the major comp<strong>one</strong>nt of the optical scann<strong>in</strong>g system. TheCIS consists of three LEDs (red, green, and blue), a light guide, the scann<strong>in</strong>g glass, the rodlens array, and a sensor array. When the CIS scans a document, the CIS does not move.Instead, documents move past the CIS.Figure 4-12. <strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> optical system (1 of 2)The formatter controls the CIS. To beg<strong>in</strong> scann<strong>in</strong>g, the formatter sends a signal to the CIS.The LEDs illum<strong>in</strong>ate and the light passes through the light guide and scann<strong>in</strong>g glass andstrikes the document. Light that the document reflects passes back through the scann<strong>in</strong>gglass and rod lens array <strong>in</strong>to the sensor array. The sensor array consists of 5,148photosensors (468 photosensors on each of 11 sensor driver circuits).

The scanner consists of these elements:● a lamp (cold-cathode fluorescent bulb)● five mirrors and a lens● a CCDFigure 4-14.<strong>HP</strong> <strong>LaserJet</strong> <strong>3020</strong> and <strong>3030</strong> optical systemThe scanner lamp illum<strong>in</strong>ates a sm<strong>all</strong> strip of the document (c<strong>all</strong>ed the raster l<strong>in</strong>e). The mirrorsdirect the light through the lens to the CCD. The CCD senses and records the light, creat<strong>in</strong>gan analog representation of the raster l<strong>in</strong>e. If the ADF is be<strong>in</strong>g used, the document thenadvances <strong>in</strong> the ADF to the next raster l<strong>in</strong>e. If the flatbed is be<strong>in</strong>g used, the scanner moduleadvances to the next raster l<strong>in</strong>e. This advanc<strong>in</strong>g and collection process cont<strong>in</strong>ues to the endof the sheet.The image data is collected <strong>in</strong> the motor controller board, where it is processed and sent to theformatter. The formatter then handles the image data, outputt<strong>in</strong>g it as a copy, send<strong>in</strong>g itthrough the LIU as a fax (<strong>in</strong> the LJ <strong>3030</strong>), or direct<strong>in</strong>g it to the computer as scanner output.ENWW <strong>HP</strong> <strong>LaserJet</strong> <strong>3020</strong> and <strong>3030</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong> unique comp<strong>one</strong>nts 93
The image data collected is 600 pixels per <strong>in</strong>ch (ppi). Each pixel has 8 bits for each of thethree colors (256 gray scale levels for each color) or a total of 24 bits per pixel (24-bit color).Scanner operationAt startup and periodic<strong>all</strong>y at other times, the scanner assembly moves systematic<strong>all</strong>y tolocate its home position. It then calibrates to a white strip located under the glass at the rightend of the scan tub.If the product detects a document <strong>in</strong> the ADF when a copy or scan is <strong>in</strong>itiated (from thesoftware or the control panel), the scan module moves to the left side of the scan tub andstops. The image is acquired as the paper is fed through the ADF past the scanner module.If no document is detected <strong>in</strong> the ADF, or if the model does not have an ADF, the scan moduleacquires the image from the flatbed glass while slowly mov<strong>in</strong>g with<strong>in</strong> the scan tub.ADF operationStandby (paper-load<strong>in</strong>g) mode: In standby mode, the pickup roller is up and the stack-stopis down, prevent<strong>in</strong>g the user from <strong>in</strong>sert<strong>in</strong>g the orig<strong>in</strong>al document too far. When a document is<strong>in</strong>serted correctly, the paper-present sensor detects its presence.The standard operation of the ADF consists of the pick, feed, and lift steps.Pick: When it receives a copy or scan command, the ADF motor engages the gear tra<strong>in</strong> tolower the pickup-roller assembly and raise the stack-stop. The first roller, c<strong>all</strong>ed the pre-pickroller, moves the top few sheets forward <strong>in</strong>to the ADF. The next roller is the pickup roller. Thisroller contacts the ADF separation pad, which separates multiple pages <strong>in</strong>to s<strong>in</strong>gle sheets.Feed: The s<strong>in</strong>gle sheet cont<strong>in</strong>ues through the path. Along the way, the form sensor, which is aset distance from the ADF glass, detects the sheet. This alerts the scanner to start when thepage reaches the glass. The scanner acquires the image, <strong>one</strong> raster l<strong>in</strong>e at a time, until itdetects the end of the page. The page is then ejected. The pick and feed steps are repeatedas long as paper is detected <strong>in</strong> the ADF <strong>in</strong>put tray.Lift: When no more paper is detected <strong>in</strong> the ADF <strong>in</strong>put tray and the form sensor detects thetrail<strong>in</strong>g edge of the last page, the last sheet is ejected and the motor turns <strong>in</strong> a sequence thatlifts the pick roller assembly to standby (paper-load<strong>in</strong>g) mode aga<strong>in</strong>.The ADF will not function when the ADF lid is open. The paper path is <strong>in</strong>complete if the ADFlid is lifted from the glass.94 Chapter 4 Operational overview ENWW
ADF paper path and ADF sensorsThe follow<strong>in</strong>g diagram shows the ADF paper path.Figure 4-15.<strong>HP</strong> <strong>LaserJet</strong> <strong>3020</strong> and <strong>3030</strong> ADF pathThe paper-present sensor determ<strong>in</strong>es if paper is <strong>in</strong> the ADF. The form sensor detects the topand bottom edges of the document. One other sensor detects an open ADF door.ADF jam detectionThe ADF has two sensors that detect paper. The paper-present sensor detects the presenceof media <strong>in</strong> the ADF <strong>in</strong>put tray. The form sensor detects media mov<strong>in</strong>g through the ADF. If ajam is detected, the ADF immediately stops the paper feed<strong>in</strong>g and a jam message appears onthe control-panel display.A jam can be detected under any of the follow<strong>in</strong>g conditions:● Document-feeder jam—When documents are detected <strong>in</strong> the ADF <strong>in</strong>put tray, and acommand to copy, scan or fax is received, the scan module travels to the left side of thescan assembly and stops beneath the ADF scanner glass. The ADF then attempts threetimes, or for about ten seconds, to advance the paper to the form sensor. If the paperdoes not advance, the scan module travels back to the home position on the right side ofthe scanner assembly. The message Document feeder mispick. Reload. appears on thecontrol-panel display.● Long-document jam—If the paper has advanced to trigger the form sensor, but thetrail<strong>in</strong>g edge is not detected with<strong>in</strong> the time <strong>all</strong>owed for a 381-mm (15-<strong>in</strong>ch) document (themaximum <strong>all</strong>owable page length for the ADF), the scanner returns to the home position atthe right side of the scanner assembly. The message Doc feeder jam. Clear, Reload.appears on the control-panel display.● St<strong>all</strong> jam—When a page that is less than 381 mm (15 <strong>in</strong>ches) long has advanced to theform sensor but has not left it with<strong>in</strong> the expected time, the paper has probably st<strong>all</strong>ed orjammed. The scanner returns to the home position at the right side of the scannerassembly. The message Doc feeder jam. Clear, Reload. appears on the control-paneldisplay.● Other—If the paper stops <strong>in</strong> the ADF and the scan module rema<strong>in</strong>s under the ADFscanner glass, an <strong>in</strong>ternal firmware error has probably occurred.

Fax functions and operation (<strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> and <strong>3030</strong> only)The follow<strong>in</strong>g sections describe the fax capabilities of the product.PSTN operationThe public switched teleph<strong>one</strong> network (PSTN) operates by hav<strong>in</strong>g a central office (CO) thatgenerates a constant voltage on the TIP and RING wires (48 V, usu<strong>all</strong>y). A device goes onhookby connect<strong>in</strong>g impedance (such as 600 ohms for the U.S.) across TIP and RING,<strong>all</strong>ow<strong>in</strong>g a l<strong>in</strong>e current to flow. The CO can detect this current and can send impulses like dialt<strong>one</strong>s. The product generates more signal<strong>in</strong>g t<strong>one</strong>s, such as dial<strong>in</strong>g digits, to tell the CO howto connect the c<strong>all</strong>. The product can also detect t<strong>one</strong>s, such as a busy t<strong>one</strong> from the CO, thattell it how to behave.When the c<strong>all</strong> is f<strong>in</strong><strong>all</strong>y connected, the CO behaves as if it were a piece of wire connect<strong>in</strong>g thesender and receiver. This is the period dur<strong>in</strong>g which <strong>all</strong> of the fax signal<strong>in</strong>g and data transferoccurs. When a c<strong>all</strong> is completed, the circuit opens aga<strong>in</strong> and l<strong>in</strong>e current flow ceases,remov<strong>in</strong>g the CO connection from both the sender and the receiver.All of this is d<strong>one</strong> with a two-wire arrangement. The two wires are c<strong>all</strong>ed TIP and RING on <strong>all</strong>ph<strong>one</strong> systems. On most ph<strong>one</strong> systems, the wires appear on p<strong>in</strong>s 3 and 4 of the RJ-11modular jack (the <strong>one</strong> on the LIU). These two wires do not have to be polarized because <strong>all</strong>the equipment works with either TIP or RING on p<strong>in</strong> 3 and the other wire on p<strong>in</strong> 4. This meansthat cables of either polarity can <strong>in</strong>terconnect and will still work.These are the basic functions of PSTN operation that are assumed <strong>in</strong> the design of the faxsubsystem. The product generates and detects the signal<strong>in</strong>g t<strong>one</strong>s, currents, and data signalsthat are required to transmit and receive faxes on the PSTN.The fax subsystemThe formatter, LIU, firmware, and software <strong>all</strong> contribute to the fax functionality. The designsof the formatter and LIU, along with parameters <strong>in</strong> the firmware, determ<strong>in</strong>e the majority of theregulatory requirements for telephony on the product.The fax subsystem is designed to support V.34 fax transmission, lower speeds (such as V.17fax), and older fax mach<strong>in</strong>es.Formatter <strong>in</strong> the fax subsystemThe formatter conta<strong>in</strong>s the modem chipset (DSP and CODEC) that controls the basic faxfunctions of t<strong>one</strong> generation and detection, along with channel control for the faxtransmissions.The CODEC and its associated circuitry act to control transmit and receive ga<strong>in</strong>s, and tocompensate for transmission signal coupl<strong>in</strong>g <strong>in</strong>to the receive channel. The formatter alsoconta<strong>in</strong>s circuitry that adds term<strong>in</strong>ation impedance to help match the teleph<strong>one</strong> networkimpedance.LIU <strong>in</strong> the fax subsystemTwo versions of LIU are used <strong>in</strong> the <strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> and <strong>3030</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong>. One is used <strong>in</strong> theNorth American, South American, and Asian countries/regions. The other is used primarily <strong>in</strong>European countries/regions.96 Chapter 4 Operational overview ENWW
The follow<strong>in</strong>g are features that are different <strong>in</strong> the European version:● a different voltage-protection device● current limit<strong>in</strong>g of the dc current● filter<strong>in</strong>g for the countries/regions that use bill<strong>in</strong>g or meter<strong>in</strong>g t<strong>one</strong>s● control of the impedance of the dc circuit through the SHUNT signalBecause the TIP and RING are not polarized, <strong>all</strong> LIU circuitry that connects to TIP and RINGis bidirectional. The LIU operates identic<strong>all</strong>y when TIP and RING are reversed.Safety isolationThe most important function of the LIU is the safety isolation between the high-voltage,transient-pr<strong>one</strong> environment of the teleph<strong>one</strong> network (TNV [teleph<strong>one</strong> network voltage]) andthe low-voltage analog and digital circuitry of the formatter (SELV [secondary extra-lowvoltage]). This safety isolation provides both customer safety and product reliability <strong>in</strong> thetelecom environment.Any signals that cross the isolation barrier do so either optic<strong>all</strong>y or magnetic<strong>all</strong>y. Thebreakdown voltage rat<strong>in</strong>g of barrier-critical comp<strong>one</strong>nts is greater than 1.5 kV.Safety-protection circuitryIn addition to the safety barrier, the LIU protects aga<strong>in</strong>st RING and over-current events.Teleph<strong>one</strong> over-voltages can be either differential mode or common mode. The RING can betransient <strong>in</strong> nature (a lightn<strong>in</strong>g-<strong>in</strong>duced surge or ESD) or cont<strong>in</strong>uous (a power l<strong>in</strong>e crossed with aph<strong>one</strong> l<strong>in</strong>e). The LIU protection circuitry provides marg<strong>in</strong> aga<strong>in</strong>st comb<strong>in</strong>ations of RINGevents.Common mode protection is provided by the selection of high-voltage-barrier criticalcomp<strong>one</strong>nts (transformer, relay, and optoisolators). The safety barrier of the LIU PCB tracesand the clearance between the LIU and surround<strong>in</strong>g comp<strong>one</strong>nts also contribute to commonmode protection.A voltage suppressor (a crowbar-type SIDACTOR) provides differential protection. This devicebecomes low impedance at approximately 300 V differential, and crowbars to a low voltage. Aseries thermal switch works <strong>in</strong> conjunction with the crowbar for cont<strong>in</strong>uous RING events, suchas crossed power l<strong>in</strong>es.When the differential RING is cont<strong>in</strong>uous, the result<strong>in</strong>g over-current causes the thermal switchto become high impedance, disconnect<strong>in</strong>g RING from the network and protect<strong>in</strong>g the crowbarfrom thermal overload. The thermal switch automatic<strong>all</strong>y resets to low impedance after theover-current condition is removed, reconnect<strong>in</strong>g RING to the network.Data pathThe magnetic<strong>all</strong>y coupled signals that cross the isolation barrier go either through atransformer or a relay. The TIP and RING signals use a transformer to cross the isolationbarrier.TIP and RING are the two-wire paths for <strong>all</strong> signals from the teleph<strong>one</strong> network. All signal<strong>in</strong>gand data <strong>in</strong>formation comes across them, <strong>in</strong>clud<strong>in</strong>g fax t<strong>one</strong>s and fax data.The teleph<strong>one</strong> network uses dc current to determ<strong>in</strong>e the hook state of the teleph<strong>one</strong>, so l<strong>in</strong>ecurrent must be present dur<strong>in</strong>g a c<strong>all</strong>. On some l<strong>in</strong>e <strong>in</strong>terfaces this current flows through thetransformer, but on the LIU, a capacitor blocks the current from go<strong>in</strong>g <strong>in</strong>to the transformer.ENWW Fax functions and operation (<strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> and <strong>3030</strong> only) 97
Block<strong>in</strong>g the current with a capacitor prevents the core of the transformer from be<strong>in</strong>g saturatedby the high dc voltage, which can affect the ac signal quality. Rather than permitt<strong>in</strong>g thecurrent to flow through the transformer, this LIU directs the current through another circuitc<strong>all</strong>ed a gyrator or dc hold circuit. This creates the path for the central office-current flow when ac<strong>all</strong> is <strong>in</strong> progress.Hook stateAnother magnetic<strong>all</strong>y coupled signal is the control signal that disconnects the downstreamteleph<strong>one</strong> devices (such as a ph<strong>one</strong> or answer<strong>in</strong>g mach<strong>in</strong>e). A control signal orig<strong>in</strong>at<strong>in</strong>g on theformatter can change the relay state, caus<strong>in</strong>g the auxiliary jack (downstream jack) to bedisconnected from the circuit.The product takes control of c<strong>all</strong>s that it recognizes as fax c<strong>all</strong>s. If the product does not directlypick up the c<strong>all</strong>, it monitors <strong>in</strong>com<strong>in</strong>g c<strong>all</strong>s for the fax t<strong>one</strong> or for the user to direct it to receive afax. This idle mode is also c<strong>all</strong>ed eavesdropp<strong>in</strong>g. This mode is active when the product is onhookbut current exists <strong>in</strong> the downstream ph<strong>one</strong> l<strong>in</strong>e because another device is off-hook.Dur<strong>in</strong>g eavesdropp<strong>in</strong>g, the receive circuit is enabled but has a different ga<strong>in</strong> from the currentthat is generated dur<strong>in</strong>g normal fax transmissions.The product does not take control of the l<strong>in</strong>e unless it detects a fax t<strong>one</strong> or the operator tells itto connect manu<strong>all</strong>y. This feature <strong>all</strong>ows the user to make voice c<strong>all</strong>s from a ph<strong>one</strong> that isconnected to the product without be<strong>in</strong>g cut off if a fax is received.Downstream current detectionThe aux ph<strong>one</strong> detect signal is optic<strong>all</strong>y coupled. This signal tells the firmware that an activeph<strong>one</strong> (or modem or answer<strong>in</strong>g mach<strong>in</strong>e) is connected to the auxiliary port of the product (theright side of the RJ-11 jack).A circuit that can detect current above a certa<strong>in</strong> threshold generates the downstream-currentdetectionsignal. The downstream current goes through a resistor, generat<strong>in</strong>g a voltage. If thisvoltage is above the threshold level, the signal changes state.The downstream-current-detection signal is coupled back to the formatter through anoptoisolator and across the safety isolation barrier. The firmware uses this signal to ensurethat the product does not go off-hook (and disconnect a downstream c<strong>all</strong>) until it has beenauthorized to do so (by a manual fax start or detection of the appropriate t<strong>one</strong>s).Hook switch controlAnother optic<strong>all</strong>y coupled signal is the hook switch control. This signal from the formattercauses an optoisolator on the LIU to activate (mak<strong>in</strong>g an open circuit <strong>in</strong>to a short circuit).When shorted, the circuit is draw<strong>in</strong>g dc current from the central office and is considered “onhook.”When open, no dc current flows and the state is considered to be “off-hook.”For pulse dial<strong>in</strong>g, the optoisolator is toggled on and off with a particular tim<strong>in</strong>g sequence togenerate pulses that the central offices of the teleph<strong>one</strong> company recognizes as dial<strong>in</strong>g digits.R<strong>in</strong>g detectAnother optic<strong>all</strong>y coupled signal on the LIU is r<strong>in</strong>g detect. R<strong>in</strong>g detect is a comb<strong>in</strong>ation ofvoltage levels and cadence (time on and time off). Both must be present <strong>in</strong> order for theproduct to detect a valid r<strong>in</strong>g.The LIU works with the firmware to determ<strong>in</strong>e if an <strong>in</strong>com<strong>in</strong>g signal is an answerable r<strong>in</strong>g.When circuits on the LIU detect a r<strong>in</strong>g voltage above a certa<strong>in</strong> threshold, a correspond<strong>in</strong>gsignal is passed to the formatter to <strong>in</strong>dicate that the r<strong>in</strong>g is above the threshold. The firmwarethen measures the amount of time that the signal is high and low, and qualifies the cadence todeterm<strong>in</strong>e whether it is a valid r<strong>in</strong>g.98 Chapter 4 Operational overview ENWW
L<strong>in</strong>e current controlThe dc current from the CO needs to have a path to flow from TIP to RING. Because thecurrent does not flow <strong>in</strong> the transformer, a path through some transistors and diodes (the dchold circuit) acts like a simulated <strong>in</strong>ductor (thus replac<strong>in</strong>g the function of the transformer). Thisdc hold circuit is the ma<strong>in</strong> comp<strong>one</strong>nt of the voltage-current characteristic between TIP andRING.Two other functions of this block of circuits are the current limit and the SHUNT for Europe.Current limit basic<strong>all</strong>y ma<strong>in</strong>ta<strong>in</strong>s a constant current from TIP to RING after the voltage reachesabout 50 mA. Even if the voltage varies, the current will rema<strong>in</strong> the same.The SHUNT function changes the impedance (the current-voltage characteristic) dur<strong>in</strong>gcerta<strong>in</strong> special events, such as pulse dial<strong>in</strong>g and when the devices goes on-hook.Dur<strong>in</strong>g such an event, the firmware tells the DSP on the formatter to activate SHUNT. Asignal goes to the LIU through an optoisolator (optic<strong>all</strong>y coupled), which changes the state ofsome transistors so that the board has a l<strong>in</strong>ear current characteristic (norm<strong>all</strong>y, it is currentlimited).Then more current can flow to the network, as required by these special events.Bill<strong>in</strong>g (meter<strong>in</strong>g) t<strong>one</strong> filtersSwitzerland and Germany provide high-frequency ac signals on the ph<strong>one</strong> l<strong>in</strong>e <strong>in</strong> order to billcustomers. The LC (<strong>in</strong>ductor, capacitor) notch filters are provided on the European LIUs toprevent these bill<strong>in</strong>g signals from adversely affect<strong>in</strong>g the data path and the dc hold circuit.An additional filter <strong>in</strong> the cable (for certa<strong>in</strong> countries/regions) can, <strong>in</strong> some cases, supplementthese LC notch filters. Because these bill<strong>in</strong>gs signals are not used <strong>in</strong> the U.S., these filters arenot present on the U.S. LIU.Fax page storage <strong>in</strong> flash memoryFax pages are the electronic images of the document page. They can be created <strong>in</strong> any ofthree ways: scanned to be sent to another fax mach<strong>in</strong>e, generated to be sent by thecomputer, or received from a fax mach<strong>in</strong>e to be pr<strong>in</strong>ted.The product stores <strong>all</strong> fax pages <strong>in</strong> flash memory automatic<strong>all</strong>y. After these pages are written<strong>in</strong>to flash memory they are stored until the pages are sent to another fax mach<strong>in</strong>e, pr<strong>in</strong>ted onthe product, transmitted to the computer, or erased by the user.These pages are stored <strong>in</strong> flash memory, which is the nonvolatile memory that can berepeatedly read from, written to, and erased. The product has 4 MB of flash memory, of which3.4 MB is available for fax storage. The rema<strong>in</strong><strong>in</strong>g 0.6 MB is used for the file system andreclamation. Add<strong>in</strong>g RAM does not affect the fax page storage because the product does notuse RAM for stor<strong>in</strong>g fax pages.Stored fax pagesThe user can repr<strong>in</strong>t stored fax pages <strong>in</strong> case of errors. The product will re-send stored faxpages after a busy signal, comm error, no answer, or a power failure. Other fax devices storefax pages <strong>in</strong> either normal RAM or short-term RAM. Normal RAM immediately loses its datawhen power is lost, while short-term RAM loses its data about 60 m<strong>in</strong>utes after a powerfailure. Flash memory ma<strong>in</strong>ta<strong>in</strong>s its data for years without any applied power.Advantages of flash memory storageFax pages stored <strong>in</strong> flash memory are persistent. They are not lost as a result of a powerfailure, no matter how long the power is off. Users can repr<strong>in</strong>t faxes <strong>in</strong> case the pr<strong>in</strong>t cartridgeruns out of t<strong>one</strong>r or the product experiences other errors while pr<strong>in</strong>t<strong>in</strong>g faxes.ENWW Fax functions and operation (<strong>HP</strong> <strong>LaserJet</strong> <strong>3015</strong> and <strong>3030</strong> only) 99
The product also has scan-ahead functionality that makes use of flash memory. Scan-aheadautomatic<strong>all</strong>y scans pages <strong>in</strong>to flash memory before a fax job is sent. This <strong>all</strong>ows the sender topick up their orig<strong>in</strong>al document immediately after it is scanned, elim<strong>in</strong>at<strong>in</strong>g the need to waituntil the fax is transmission is complete.Because fax pages are stored <strong>in</strong> flash memory, not RAM, more RAM is available to handlelarger and more complicated copy and pr<strong>in</strong>t jobs.100 Chapter 4 Operational overview ENWW

The <strong>HP</strong> <strong>LaserJet</strong><strong>3020</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong> product does not operate as a fax<strong>in</strong>g device.A digital subscriber l<strong>in</strong>e (DSL) uses digital technology over standard copper ph<strong>one</strong> wires. DSLservices rely on an AM radio wave that has a range of 600 kHz to 2.2 GHz. The <strong>HP</strong> <strong>LaserJet</strong><strong>3015</strong> and <strong>3030</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong> is a Group 3 fax device, which operates at about 200 kHz (below theDSL capability) and is not directly compatible with digital signals. However, if specified dur<strong>in</strong>gthe DSL l<strong>in</strong>e setup, the signal on a DSL l<strong>in</strong>e can be separated so that some of the bandwidthis used to transmit an analog signal (for voice and fax) while the rema<strong>in</strong><strong>in</strong>g bandwidth is usedto transmit digital data. Split the signal to use both the teleph<strong>one</strong> or fax and the computer onthe same l<strong>in</strong>e and at the same time.NoteNot <strong>all</strong> pr<strong>in</strong>ters and faxes are compatible with DSL services. <strong>HP</strong> does not guarantee that the<strong>HP</strong> <strong>LaserJet</strong> <strong>all</strong>-<strong>in</strong>-<strong>one</strong> product will be compatible with <strong>all</strong> DSL service l<strong>in</strong>es or providers.The DSL modem requires a high-pass filter. Sometimes when DSL service is <strong>in</strong>st<strong>all</strong>ed, theservice provider supplies a splitter, which <strong>in</strong>cludes a low-pass filter, for the normal houseph<strong>one</strong> wir<strong>in</strong>g. If not, the user should contact the DSL provider, and request a filter or splitter toenable a fax modem to operate on the l<strong>in</strong>e.Note<strong>HP</strong> recommends discuss<strong>in</strong>g DSL l<strong>in</strong>e setup options with the DSL service provider.
