Cleaning the Scanner
If the quality of data read from cut sheets or ID cards is poor, scanner cleaning is required. Periodic cleaning is
recommended. The cleaning period is once a week or every 2,000 checks.
Turn off the product and open the scanner cover. Gently wipe the glass using a soft, dry cloth.
• Do not use detergent, water, or other liquid for cleaning. Doing so creates the risk of dirt adher-
ing to the glass.
• If oil, grease, or other similar matter gets on the scanner glass, wipe it with a cloth moistened
with alcohol. However, make sure that liquid does not come into direct contact with the scanner
glass.
