Maintenance and Troubleshooting
This chapter provides information necessary to maintain your scanner. These
topics are covered:
• Cleaning the windows
• If the Scanner does not scan
• If the Decoder does not decode
For optimum performance the scan and return signal windows should be
clean. When they are clean, you will barely see the reflection of the laser
beam on the window.
To clean the scan 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
laser light is not harmful, precautions should be taken to avoid
looking into the beam.
2. Verify that the POWER indicator on the decoder is OFF.
3. Dust off the scan window and adjacent areas with optics rated air.
4. Clean the window using 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.
!
ATTENTION: Do not use abrasive materials, such as dispos-
able paper wipes, to clean the plastic scan window. Disposable
wipes usually contain glass fibers which will scratch and cloud
the window.
5. Turn the decoder ON.
6. Verify operation.
