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.
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
