Chapter 5 — Upgrading, Troubleshooting, and Cleaning the CV60
Problems While Scanning Bar Codes (continued)
Problem
You scan a valid bar code label to enter
data for your application. The data
decoded by the scan module does not
match the data encoded in the bar
code label.
The scanner does not read the bar
code labels quickly, or scanning beam
seems to be faint or obscured.
The scanner will not read the bar code
label.
You selected 1551E or 1553 and
enabled the scanner port, but the
scanner does not scan.

Solution
The computer may have decoded the bar code label in a
symbology other than the label's actual symbology. Try
scanning the bar code label again. Make sure you scan
the entire label. To operate the computer quickly and
efficiently, you should enable only the bar code
symbologies that you are going to scan.
The scanner window may be dirty. Clean the window
with a solution of ammonia and water. Wipe dry. Do
not allow abrasive material to touch the window.
Try these possible solutions in order:
• Make sure you aim the scanner beam so it crosses the
entire bar code label in one pass.
• The angle you are scanning the bar code label may
not be working well, or you may be scanning the
label "straight on." Try scanning the bar code label
again, but vary the scanning angle.
• The bar code label print quality may be poor or
unreadable. To check the quality of the bar code
label, try scanning a bar code label that you know
will scan. Compare the two bar code labels to see if
the bar code quality is too low. You may need to
replace the label that you cannot scan.
Make sure that the application you are running on the
computer is expecting input from a bar code. You may
need to type this information instead of scanning it.
Try these possible solutions in order:
• Select ASCII as the scanner model.
• Make sure that you are using the correct cable and
that it is attached correctly (when you attach the
scanner to the port, it should emit a single power up
beep).
• Try enabling the port state using Intermec Settings.
• Try upgrading the scanner firmware.
