Conditions for Multifeed Detection
Multifeed is an error where two or more sheets are fed through
the ADF at once. It is also called a multifeed when a different
document length is detected.
Multifeed detection is performed by either checking the
overlapping of documents, length of the documents, or the
combination of both. The following conditions are required for
an accurate detection.
Detection by Overlapping
2
 Paper weight: 27 to 413 g/m (7.2 to 110 lb)
 Do not punch holes within 35 mm (1.38 in.) over the center of the
document. See "Fig. 1" (page 45).
 Do not attach other documents within 35 mm (1.38 in.) over the
center of the document. See "Fig. 1" (page
Detection by Length
 Load documents of the same length in the ADF paper chute (feeder).
 Variance in document lengths: 1% or less
 Do not punch holes within 35 mm (1.38 in.) over the center of the
document. See "Fig. 1" (page 45).
Detection by Overlapping and Length
 Load documents of the same length in the ADF paper chute (feeder).

such as plastic cards will be falsely detected as multifeed.
In that case, to scan documents successfully, use the multifeed
window display function of the scanner driver, use the Intelligent
Multifeed function, or disable the multifeed detection.
Multifeed cannot be detected for the top 30 mm of a document.
