Troubleshooting the Scanner
If the bar code does not scan:
¨
Change the scanner’s angle slightly and try again.
¨
Move the scanner four to eight inches away from the bar code.
Adjust this distance as needed to find the correct distance.
¨
Try scanning another bar code that you have scanned
successfully. If that scan is successful, the scanning problem
may be with the bar code.
¨
Move to a more dimly lit area.
¨
Ensure there are no voids (streaks) in the bar code symbol.
¨
Clean the scanner window. See “Cleaning” for more
information.
¨
If the scanner stays in the same place without scanning
anything for awhile, the scanner may appear to “time out.” If
this happens move the scanner slightly and then towards the
bar code you want to scan. The scanner should scan the bar
code. Make sure you do not scan data twice or
accidentally scan the wrong data.
¨
Before you call Service, print a set of test labels. The test
labels contain information to help Service diagnose mechanical
and setup problems. To print a set of test labels, press f
when you see “Print Mode Ready.”
Cleaning
Clean the scanner window whenever it appears to be dirty or
smeared.
To clean it:
1. Moisten a soft cloth with water.
2. Wipe the window until it is completely clean.
