Maintenance
Your device provides reliable and efficient operation with a minimum of care. Although specific maintenance is not required, the
following periodic checks ensure dependable operation:
Cleaning the Device
Reading performance may degrade if the scanner’s window is not clean. If the window is visibly dirty, or if the scanner isn’t
operating well, clean the window with a soft cloth or lens tissue dampened with water (or a mild detergent- water solution).
If a detergent solution is used, rinse with a clean lens tissue dampened with water only.
The scanner housing may also be cleaned the same way.
Inspecting Cords and Connectors
Inspect the interface cable and connector for wear or other signs of damage. A badly worn cable or damaged connector
may interfere with scanner operation. Contact your distributor for information about cable replacement. Cable replacement
instructions are on
Replacing Cable in the Scanner
The standard interface cable is attached to the scanner with an 10-pin modular connector. When properly seated, the connec-
tor is held in the scanner by a flexible retention tab. The interface cable is designed to be field replaceable.
•
Order replacement cables from Youjie or from an authorized distributor.
•
When ordering a replacement cable, specify the cable part number of the original interface cable.
Troubleshooting the Scanner
The scanner automatically performs self-tests whenever you turn it on. If your scanner is not functioning properly, review
the following Troubleshooting Guide to try to isolate the problem.
Is the power on? Is the aimer on?
If the aimer isn’t illuminated, check that:
•
The cable is connected properly.
•
The host system power is on (if external power isn’t used).
Is the scanner having trouble reading your symbols?
If the scanner isn’t reading symbols well, check that the scanner window is clean and that the symbols:
•
Aren’t smeared, rough, scratched, or exhibiting voids.
Do not submerge the scanner in water. The scanner’s
housing is not watertight.
Do not use abrasive wipes or tissues on the scanner’s
window – abrasive wipes may scratch the window. Never
use solvents (e.g., alcohol or acetone) on the housing or
window – solvents may damage the finish or the window.
