3.3 Cleaning the ADF
As a Guideline, clean the ADF every 1,000 scanned sheets. Note that this guideline varies accord-
ing to the type of documents you scan. For example, it may be necessary to clean the ADF more
frequently if documents are scanned when the toner is not sufficiently fixed on the printout.
• The glass surface inside the ADF becomes hot during the operation of the scanner.
Before you start to clean the inner parts of the scanner, disconnect the AC adapter from the
power outlet, and wait at least 15 minutes to let the glass cool down.
• When you perform cleaning, make sure that the inside of the scanner is free of any foreign
object, and be careful not to get your hand or the cloth caught on the pick spring (metal
part) as a deformed pick spring (metal part) may cause injury.
