Problems While Scanning Bar Codes

Problem
You cannot see a red beam of light from the
scanner when you press the Scan button and
aim the scanner at a bar code label.
When you release the Scan button, the Good
Read LED does not turn off.
You have an input device attached to the
terminal and it cannot read any bar codes.
The input device attached to the terminal
does not appear to work well or read bar
code labels very quickly.
The scanner will not read the bar code label.

If you cannot scan bar code labels or you are having trouble with the scan
module, check these possible problems.
Solution
There are two possible problems:
•
You may be too far away from the bar code label. Try moving
closer to the bar code label and scan it again.
•
You may be scanning the bar code label "straight on." Change the
scanning angle and try again.
You can test the effective range of the scanner. Move within 0.6
meters (2 feet) of a wall and test the scanner. You need to be within
the scanning range to scan bar code labels. For help on scanning
distances, see "Specifications" in Appendix A.
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 may not be using an input device that is supported with the
terminal. Make sure you are using one of the supported input
devices.
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 you are using.
If you are using the advanced long-range scanner, you may not be
able to scan the bar codes in this manual. However, you can still
send commands through the serial port or network. For help, see
Chapter 2, "Configuring and Managing the Terminals," in the 2400
Family system manual.
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 TRAKKER Antares 2400 Menu System to check the
symbologies. On the Symbologies Menu, each symbology that is
enabled has an asterisk (*) 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.
