•
When scanning semi-transparent documents,
set the density to light to avoid bleed through.
•
To prevent the rollers from becoming dirty,
avoid scanning documents containing large
areas written or filled in pencil. If scanning of
such documents is unavoidable, clean the
rollers frequently.
ATTENTION
•
Carbonless paper contains chemical
substances that may damage the Pad ASY or
rollers (e.g. Pick roller) when documents are
fed. Pay attention to the following:
Cleaning : If pick errors occur fre-
quently, clean the Pad ASY
and Pick rollers.
For details on cleaning the
Pad ASY and Pick rollers,
see "5.3 Cleaning the
ADF."
Replacing parts: The service life of the Pad
ASY and Pick rollers is
sometimes shortened
when scanning medium-
grade paper documents.

When the manuscript of Wood containg
