* Use a surge protector on the power line and the
phone line (for fax machines), not just a power
strip.
SPOTS ON THE PAGE
If spots appear on the page, like toner is
being “dropped” on the page, the problem is
usually the developer unit. The developer unit is
seldom able to be rebuilt and should be replaced.
DOUBLE IMAGING
The main cause of the print being
duplicated in areas where they are not wanted is
the fuser assembly. An improper combination of
toner and drum in a toner cartridge could also be
the problem. Faxing a page that has letter head
printed with thermal ink may cause the image to
be transferred to the rest of the page.
PAPER JAMS
* Moist paper or specialty paper (checks, slick
paper) can cause jams.
* A machine dirty with paper dust can cause a
jamming problem. Wipe the feed tires and the
interior of the machine with a cloth.
DARK PAGES
* Check to ensure the density is not set for too
dark a setting.
* The drum may need to be replaced.
* The toner cartridge could have a problem. Try
replacing to see if that corrects the problem. If it
does, notify your supplier.

COMMON PAINT DEFECTS AND REMEDIES
(DO YOU KNOW?)
CHIPPING - Chipping of paint film is due to excessive
use of putty or due to very thick coat of paint or
defective surfaces.
SOLUTION - Regulate the use of putty and paint.
CHALKING - Chalking occurs when ultraviolet rays
cause the paint binder to disintegrate. It can happen
when interior paints are used for exterior surfaces.
SOLUTION - Remove any unstable paint films. Allow
the wall to dry thoroughly, and repaint with a
recommended paint. Make sure the paint is not
adulterated with foreign materials.
CISSING - Cissing or tiny craters are caused by oily or
greasy surface/due to water based paints being
applied over glossy or smooth enamel paints.
SOLUTION - Clean the surface thoroughly with soap
solution and water. Roughen the enamel paint with
Sandpaper or use a barrier coat of matt primer.
EFFLORESCENCE - Efflorescence or formation of
white powdery deposit on walls after painting is
caused due to salts present in the building material
like brick and mortar, which surface later on.
SOLUTION - Give a long time gap between
plastering and painting (about 6 months including
one monsoon) Use paint with a porous film like
emulsions and distempers.
