Cleaning the RealScan 7872
Keeping the scan windows clean helps keep the read rate exceptionally high. During
normal operation the scan windows get dirty, and if you permit the dirt to accumulate,
performance degrades to the point where the scanner cannot read bar codes. On the
RealScan 7872 Scanner that includes the Operator Convenience option, the Please Clean
Window indicator flashes when the scan windows need cleaning. The window can be
cleaned anytime it appears dirty or performance seems to be degrading.
To clean the scan window, use a soft cloth moistened with a common, non-abrasive,
liquid window cleaner. Be sure to spray the cleaner onto the cloth, not directly onto the
RealScan 7872
Caution:
Scale problems can occur from debris collecting under the Top Plate. It is very
important to keep the area under the Top Plate clean and free of debris to prevent
interference when weighing items. Cleaning under the top plate should become part of
the regular cleaning duties in your store.
