The inside of the scanner (ADF) needs to be cleaned regularly for every certain number of sheets scanned. The
scanner records the number of sheets scanned so that you can check the number of sheets scanned after you
cleaned it last.
For information on how to check the number of sheets scanned, refer to Settings Related to Sheet Counters
(page 162).
ATTENTION
Cleaning cycles may vary depending on the condition of the documents. Also, cleaning must be performed
more frequently when the following types of documents are scanned:
● Smooth-faced documents such as coated paper
● Documents with printed text/graphics that almost cover the entire surface
● Chemically-treated documents such as carbonless paper
● Documents containing a large amount of calcium carbonate
● Documents written in lead pencil
● Documents on which the toner is not sufficiently fused
