Maintenance and
Troubleshooting
This chapter provides troubleshooting information to assist with
problem detection and resolution. It also describes how to remove
the scan window for cleaning or to replace the window.
!
ATTENTION: No user maintenance of the scanner is
required. Do not open the enclosure! Removing or
attempting to remove sealed screws will void the
warranty.
For optimum performance the scan window should be clean.
To clean the scan window:
!
ATTENTION: Only use reagent grade alcohol to
clean the window. Do not use organic solvents. Do
not use abrasive materials, such as disposable paper
wipes, to clean the plastic scan window. Disposable
wipes usually contain glass fibers which will scratch
and cloud the window.
1. Turn the decoder off.
!
ATTENTION: Do not attempt to clean the window
while the scanner is turned on. Although momentary
exposure to the laster light is not harmful, precautions
should be taken to avoid looking into the beam.
2. Verify that the POWER indicators on both the scanner and the
decoder are OFF.
3. Dust off the scan window and adjacent areas with optics rated air.
4. Clean the window using a reagent grade alcohol, cotton-tipped
swabs and lens cleaning paper. To avoid smearing film and
fingerprints, rotate the cotton-tipped swab while it’s on the
window, nearly one full turn. Then discard it.
5. Turn the decoder ON. The POWER indicators on both the
decoder and scanner should be ON.
When the window is clean, you will barely see the reflection of the
laser beam on the window.
