5.3 Cleaning Inside of the Scanner
Clean inside of the scanner with a cloth moistened with Cleaner F1.
In an alternating succession of scanning documents, the accumulated paper-powder and 
dust inside the scanner causes a scanning error.
As a guideline, clean the ADF every 200 sheets of documents. Note that this guideline 
varies according to the type of documents you are scanning. For example, the ADF must 
be cleaned more frequently when scanning documents on that the toner has not been 
sufficiently fixed on.
Clean the ADF according to the following procedure referring to the illustrations.
1.
Open the ADF while pulling the Cover open lever. 
2.
Clean the following locations with a cloth moistened with Cleaner F1.
ATTENTION
• Never use water or neutral detergent to clean the inside of the scanner.
• Do not use aerosol sprays to clean the scanner. Aerosol sprays cause dirt 
and dust to enter the scanner, resulting in the scanner failure, malfunction 
and image error.
