5.2 Cleaning the ADF
The ADF should be cleaned after approximately every 1,000 scanned sheets. However, this criteria
varies according to the type of documents scanned. For example, it may be necessary to clean the
ADF more frequently when documents with insufficiently fused toner are scanned.
5.2.1 Cleaning the ADF
1. Push the ADF release button, then hold both sides of the top cover and lift it open.
• The glass scanner windows inside the ADF can become hot when the
scanner is used.
Before cleaning inside the scanner or replacing any parts, turn off the
power, unplug the AC adapter from the outlet, and wait for at least 15
minutes.
The power does not need to be turned off when cleaning the feed rollers.
• 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.
Be careful that the top cover does not shut on your
fingers.
