Conditions for Multifeed Detection

A multifeed is an error when two or more sheets are fed through the ADF at once or when a different
document length is detected.
Multifeed detection is performed by either checking the overlapping of documents, length of the documents,
or a combination of both.
The following conditions are required for an accurate detection:
 Load documents of the same paper weight in the Paper Guides.
 Paper weight must be between 7 and 110 lb (27 to 413 g/m
 Do not punch holes within 1.57 in. (40 mm) of the document's center.
 Do not attach other documents within 1.57 in. (40 mm) of the document's center.
The document must be centered at the Pick Up Roller.

 Scanning thick documents, such as plastic cards, may cause a false multifeed error. If this happens,
disable multifeed detection.
