z 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 on cleaning the pad assy and pick roller, refer to "Chapter 7
Scanner Care" (page 423).
Replacing parts:
The service life of the pad assy and pick roller may be shortened when
compared to scanning only wood containing paper documents.
z 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.
z When scanning photographs, the face of the photograph may become
damaged.
z When scanning semi-transparent documents, set the scan [Brightness] to
"Light" to avoid image bleed through.
z To prevent the rollers from becoming dirty, avoid scanning documents con-
taining large areas written or filled in with pencil. If scanning of such docu-
ments is unavoidable, clean the rollers frequently.
z To operate correctly, the ADF requires the leading edges of all document
sheets be evenly aligned. Make sure that curling of the leading edge is
within the following tolerances:
More than
30mm
