Scanning Bar Code Labels

This message may be displayed in conjunction with another
specific fault message showing the cause of PutDisk
interruption. It means that although the drive update was
attempted, the original files on the target drive have not been
altered and are therefore safe to use.
If you cannot scan bar codes with the reader, locate your problem in the list
and follow the instructions:
You cannot see a red light when aiming at a wall. You may be too far from the
wall. Move within 2 feet of the wall and test the scanner again. Or test the
scanner by pointing it at the floor.
The scanner will not register the bar code label you are trying to scan. Make sure
you aim the beam so it crosses the entire label in one pass. If your scanner still
will not register the scan, it may mean that you did not enable the symbology
of the bar code. For help, see “Choosing the Symbologies the Reader Will
Decode” in Chapter 5.
If you still have trouble with the scanner, perform these checks:
• Inspect the print quality of the bar code. Try scanning a bar code label that
you know scans. Compare the two bar code labels. You may need to
replace the label that cannot be scanned.
• Make sure the reader is turned on. Press to turn the reader on.
• You try to scan a bar code label and the scanner turns off or will not turn
on. If the reader is chirping every 5 seconds and the Battery icon is
displayed, you have a low NiCad battery pack. You must turn off the
reader and replace the battery pack.
• You scan a bar code label that contains a valid configuration command, but
the reader beeps and displays an error message such as, “Bad command or
filename.” Make sure the Configuration Manager TSR is loaded into
memory. If it is not loaded, you cannot scan configuration commands. Type
cfgmgr and press to load Configuration Manager and rescan the bar
code label.
• You scan a bar code label to enter data at the DOS prompt, but the reader
beeps and displays an error message such as, “Bad command or filename.”
Make sure the application that is expecting the data is running. If
necessary, start the application and scan the bar code again.
