6.3 Cleaning Inside the Scanner
Clean the interior of the scanner with a cloth slightly moistened with Cleaner F1 or the
Cleaning Wipe.
Scanning repeatedly may cause dust and paper dust to accumulate inside the scanner
resulting in a scanning error.
As a guideline, the inside of the scanner should be cleaned every 1,000 sheets scanned.
However, this criteria varies according to the type of documents scanned. For example, it
may be necessary to clean the scanner more frequently when documents with
insufficiently fused toner are scanned.
1. Turn off the scanner power and wait for at least 15 minutes.
For details, refer to "2.1 Turning the Power On/Off" (page 49) .
2. Unplug the power cable from the AC outlet.
CAUTION
The glass scanner windows inside the ADF can become hot when the
scanner is used.
Turn off the scanner, unplug the power cable, and wait for at least 15
minutes before cleaning.
ATTENTION
 Do not use water or mild detergent to clean the inside of the scanner.
 When a large amount of the cleaner is used, it may take some time until it is dry. Use a small
amount to moisten the cloths. Also, wipe off Cleaner F1 well from the part with a dry cloth.
