Problems While Scanning Bar Codes (continued)
Problem Solution
When you release the Scan button, the
Good Read LED does not turn off.
The Good Read LED will remain on if you configure
the terminal to use edge triggering. If you configure the
terminal for level triggering and the Good Read LED
remains on, there may be a problem. Press the Scan
button again without scanning a bar code label. If the
LED is still on, contact your local Intermec service
representative.
You have an input device attached to the
terminal and it cannot read any bar
codes.
You may not be using an input device that is supported
with the terminal. Make sure you are using one of the
supported input devices.
The input device attached to the
terminal does not appear to work well or
read bar code labels very quickly.
Try setting the Scanner Selection command to the
specific input device you have attached. Check the bar
code symbologies you have enabled on the terminal.
Enable only the symbologies that you are using.
The scanner will not read the bar code
label.
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 scans.
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 the bar code symbology you are scanning is
enabled. Use the Configuration Utility to check the
symbologies. On the Symbologies Menu, each
symbology that is enabled has a check mark (➼ ) next to
the name of the symbology. If your bar code symbology
is disabled, enable it and then try scanning the bar code
label again.
Make sure that the application you are running on the
terminal is expecting input from a bar code. You may
need to type this information instead of scanning it.
The scanner does not read the bar code
labels quickly, or the scanning beam
seems to be faint or obscured.
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.
