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 g/m
2
(5.4 to 56 lb) / 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 g/m
2
(5.4 to 56 lb) / 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.
ATTENTION
The above condition applies when the document is set to the center of the pick roller width.
