3.2 Cleaning the ADF
As a guideline, clean the ADF after every 5,000 scans. Note that this guideline varies according to
the type of documents you are scanning. 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.
■ Cleaning Method
1. Open the ADF cover while pushing down the ADF button.
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 3
minutes to let the glass cool down.
Be careful, the ADF cover may close and pinch your
fingers.
