ATTENTION
Carbonless paper contains chemical substances that may damage the pad assy or the pick
and other rollers when documents are fed. Pay attention to the following:
cleaning
If pick errors occur frequently, clean the pad assy and pick roller.
For details about cleaning the pad assy and pick roller, refer to
Care" (page 356).
Replacing parts
The service life of the pad assy and pick roller may be shortened when compared to
scanning only wood containing paper documents.
When wood containing paper manuscripts are scanned, the life of the pad assy and pick
roller may be shortened compared with the case where woodfree paper manuscripts are
scanned.
When scanning photographs, the face of the photograph may become damaged.
HINT
When scanning semi-transparent documents, set the scan [Brightness] to [Light] to avoid
image bleed through.
Clean the rollers as frequently as possible when you scan documents written in pencil,
because the pencil may smudge the document. Unclean rollers may also cause a paper feed
error.
For details about cleaning the pad assy and pick roller, refer to
(page 356).
