Problems Reading Bar Codes Problem Solution You cannot see the illumina- • tion beam or frame from the imager when you press the • Scan button and aim the im- ager 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 ecom instruments 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 ecom instruments 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 ecom instruments 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 more information, see 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. 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 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. The input device attached to the computer does not work well or read bar code labels very quickly. Set the Scanner Model command to the specific attached input device. Check enabled bar code symbologies and enable only the symbologies being used. 62 Use ScanDiagnostic to Troubleshoot the Scanner Use the ScanDiagnostic application to troubleshoot problems such as the inability to read a bar code or a scanner that does not turn on. 1 From the Home menu, tap Start > ScanDiagnostic. 2 From the Scan Health screen, select the scanner you want to troubleshoot and then tap Diagnose.
