ATTENTION
Carbonless paper contains chemical substances that may harm the Pad
ASSY or rollers (e.g. Pick roller) when documents are fed. Pay attention to
the following:
Cleaning: If pick errors occur frequently, clean the Pad ASSY
and the Pick roller. For details on cleaning the Pad
ASSY and the Pick roller, refer to "3.2 Cleaning the
ADF" on page 54.
Replacing parts: The service life of the Pad ASSY and the Pick roller
may be shortened compared to the case of scanning
wood containing paper documents.

When scanning wood containing paper, the life of the Pad ASSY and the
Pick roller may be shortened compared to the case of scanning woodfree
paper.
