Documents to Avoid Scanning
The documents in this list can be scanned, but please note that scanning documents of this type will
reduce the life of the scanner. Maintenance will be required more often and replaceable parts will wear
faster. These types of documents will jam more frequently and damage to the original documents may
occur. If you do choose to scan these document types, do not scan large batches. This type of use is
not covered under the scanner warranty and alters replacement parts life expectancy.
We recommend you limit the amount or completely avoid scanning documents that are in this list.
• Curled, wrinkled or folded documents may cause paper jams or multiple pages being fed through
the scanner at one time.
• Perforated or punched paper that could tear when the separation roller engages.
• Coated paper or photographs where the coating can flake off during scanning and leave residue
in the scanner.
• Extremely smooth, shiny, or highly textured paper may cause the paper feed rollers to slip across
the page and cause the scanner to report a paper jam.
• Carbonless copy paper may tear while being fed through the scanner and the pressure of the
rollers may leave streaks on the page. The chemical coating on this paper will rub off on the rollers
during the scan process, increasing the frequency of miss-feeds and paper jams.
• Partially transparent paper such as tracing paper as any images from the opposite side of the
page or black background will appear in the scanned images.
