Conditions for Multifeed Detection
Multifeed is an error when 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
Load documents of the same thickness onto the hopper.

Paper weight: 20 to 209.3 g/m
/ 0.025 to 0.25 mm (0.001 to 0.010 in.)
Do not punch holes within 35 mm (1.38 in.) of the vertical lines in the
left, center and right of the document. See Fig.1.
Do not attach other documents within 35 mm (1.38 in.) of the vertical
lines in the left, center and right of the document. See Fig.1.
Detection by length
Load documents of the same length onto the hopper.
Variance in document lengths: 1% or less
Do not punch holes within 35 mm (1.38 in.) over the vertical center
line of the document. See Fig. 2.
Detection by overlapping and length
Load documents of the same thickness and the same length onto the
hopper.

Paper weight: 20 to 209.3 g/m
/ 0.025 to 0.25 mm (0.001 to 0.010 in.)
Variance in document lengths: 1% or less
Do not punch holes within 35 mm (1.38 in.) of the vertical lines in the
left, center and right of the document. See Fig.1.
Do not attach other documents within 35 mm (1.38 in.) of the vertical
lines in the left, center and right of the document. See Fig.1.
The above condition applies when the document is set to the
center of the pick roller width.

The rate of multifeed detection may drop with some
documents. Multifeed cannot be detected in the area of
15 mm from the leading edge of the document.
