Maintenance
The 3800/3900 provides reliable and efficient operation with a minimum of care.
Although specific maintenance is not required, the following periodic checks
ensure dependable scanner operation:
Cleaning the Scanner's Window
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 facial tissue dampened with water (or a mild detergent- water
solution). If a detergent solution is used, rinse with a clean tissue dampened
with water only.
The scanner's housing may also be cleaned the same way.
!
Caution:
Do not submerge scanner in water. Do not use abrasive wipes or
tissues on the scanner's window. Abrasive wipes may scratch the
window.
Never use solvents, e.g., acetone, benzene, ether, or phenol-based
agents on the housing or window. Solvents may damage the finish or
the window.
Inspecting Cords and Connectors
Inspect the scanner's 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
page
14-1.
Replacing the Interface Cable
The standard interface cable is attached to the scanner with an 10-pin modular
connector. When properly seated, the connector is held in the 3800 scanner's
handle by a flexible retention tab. The 3900 connector is located in the pod at
the end of the 3900 cable. The interface cable is designed to be field replace-
able.
