• When scanning semi-transparent documents, set the density to light to
avoid bleed through.
• To prevent the rollers from becoming dirty, avoid scanning documents con-
taining 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 ASSY or rollers (e.g. Pick roller) when documents are fed. Pay atten-
tion to the following:
Cleaning: If pick errors occur frequently, clean the Pad ASSY and
Pick rollers.
For details on cleaning the Pad ASSY and Pick rollers,
see "3.3 Cleaning the ADF" (page. 47).
Replacing parts: The service life of the Pad ASSY and Pick rollers is
sometimes shortened when scanning medium-grade
paper documents.
• When the manuscript of Wood containg paper is read, the life of a Pad
ASSY and a Pick roller may become short compared with the case where
the manuscript of Woodfree paper is read.
