ATTENTION
• Carbonless paper contains chemical substances that may damage 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 ancd the
Pick roller, refer to "Chapter 3 Daily Care" on page 3-1.
Replacing parts: The service life of the Pad ASSY and Pick roller may be
shortened compared to the case of scanning wood con-
taining paper documents.
• If paper containing wood is scanned, the service life of the Pad and Pick
roller may become shorter than that of the Pad and Pick roller used for
scanning only woodfree paper.
• The pad or rollers of the scanner could be damaged if photographs or
sheets of paper attached to the scanned document have contact with the
pad or rollers during scanning.
• Scanning documents of calendered paper such as photographs may
damage the surface of them.
