3.2 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 of 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.
■ Cleaning the ADF
1. Open the ADF by pushing on the ADF button and turning the ADF cover to the front.
Be careful, the ADF cover may close and pinch your finger.
