Maintenance
Appendix D — Maintenance
The POWERSCAN D8590 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 POWERSCAN D8590 Window
The POWERSCAN D8590 has a clear, anti-reflective coated optical window that protects
the POWERSCAN D8590
illumination system and optics. The window should be clean to allow
optimum performance.
The POWERSCAN D8590 uses technology that is much like a digital
camera, and marks or debris on
the window will interfere with image captures. Avoid touching
the coated surface, as fingerprints
may impede decode performance.
In many cases the window can be cleaned by wiping with a lint-free lens cloth to remove
dust, de
bris, and fingerprints. Care should be taken not to apply too much pressure, as a
trapped particle may scratch the window.
If cleaning of the window becomes necessary, follow this procedure:
• Use a minimal amount of Isopropyl Alcohol to dampen. Do not saturate
the surface, as
this may cause streaking.
•
Drag the moistened cotton swab, cotton ball, or soft, clean cloth across the coated surface.
Do not rub.
• Repeat this procedure until no contaminants remain.
Note: Many products designed
for cleaning plastic lens eyewear, such as pre-moistened
towelettes or lens cloths, can be used to clean the POWERSCAN D8590 window.
Cleaning the POWERSCAN D8590 Housing
If the housing becomes dirty, clean it with a soft, non-abrasive cloth that has been moistened
with water. A mild detergent may be used to clean the housing, but the detergent should
then be rinsed away with a water-moistened cloth.
Caution: Do not submerge the
PO
WERSCAN D8590 in water. The housing is not water-
tight. Do not use abrasive cloths or tissues on the POWERSCAN D8590 window — abrasive
cl
oths or tissues may scratch the window.
