Troubleshoot Reading Bar Codes

Use this section to troubleshoot problems that may prevent you from

being able to read a bar code, such as the symbology not being enabled.

Problems Reading Bar Codes

Problem Solution

You cannot see the illumination

beam or frame from the imager

when you press the Scan button

and aim the imager at a bar code

label.

• 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 reading the bar code label “straight on.” Change

the reading angle and try again.

• The imager hardware trigger might be disabled in Intermec

Settings. To check the setting go to Start > Settings >

Systems > Data Collection > Scanner Settings. Hardware

trigger should be checked.

When you release a Scan button or

handle trigger, the Good Read

light does not turn off.

The Good Read light will remain on if you configure the

computer to use continuous/edge triggering. If you configure

the computer for level triggering and the Good Read light

remains on, there may be a problem. Press one of the Scan

buttons or pull the trigger again without scanning a bar code

label. If the light is still on, contact your local Intermec

representative.

The scanner will not read the bar

code label.

• Aim the scanner beam to cross the entire bar code label in

one pass. Vary the scanning angle.

• Check the quality of the bar code label. Scan 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 the bar code symbology is enabled and

configured correctly. Use Intermec Settings to check the

symbologies. Expand Data Collection > Symbologies

beneath devices listed (scanner, virtual wedge) to check and

enable symbologies, then scan the bar code label again.

• Make sure the computer application is expecting input

from a bar code. You may need to type this information

instead.

• The scanner may not be turned on or the scanner may be

unable to scan a specific bar code. Run the ScanDiagnostic

application to help you troubleshoot the problem. For
