Maintenance
PSC Scanners are designed to provide trouble-free operation
throughout their lives. They contain no components that require peri-
odic maintenance. Optimum performance may be ensured by follow-
ing the preventive maintenance procedures suggested below. If
scanning performance declines, please follow these procedures.
Cleaning
A dirty scan window can impair scanning performance. When the
window appears to be dirty or smeared, clean it by wiping with a
slightly damp cloth or facial tissue. Water or a suitable cleaning solu-
tion such as Windex™ may be used on the cloth. The plastic case of
your scanner can also be cleaned in this manner.
Inspection
Periodically inspect scanner cords and cables for wear and other
signs of damage which may interfere with the proper operation of the
unit. A badly worn cord or cable should be replaced immediately.
Replacement cords and cables can be obtained by contacting your
PSC Customer Service Representative.
Routinely examine scanners for signs of damage. A badly dented
enclosure may cause interference with internal components resulting
in damage to, or malfunction of the unit. Units with damage to the
enclosure should be returned to the factory for repair. Please refer to
Service and Warranty Section.
NOTE
Never use solvents (e.g., alcohol) on the enclosure; they
may damage the finish of the scanner.
