Area Not to be Perforated
An error may occur when there are punched holes in the area
shaded in light blue in the following figure. Such documents
can be scanned by using the flatbed (ScanPartner SP30F).
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
z
Paper weight: 41 to 209 g/m
2
(11 to 56 lb)
z
Do not punch holes within 35 mm (1.38 in.) over the center of the
document. See Fig.1.
z
Do not attach other documents within 35 mm (1.38 in.) over the
center of the document. See Fig.1.
Detection by length
z
Load documents of the same paper length in the ADF paper chute
(feeder).
z
Variance in document lengths: 1% or less
z
Do not punch holes within 35 mm (1.38 in.) over the center of the
document. See Fig.1.
Detection by overlapping and length
z
Load documents of the same paper length in the ADF paper chute
(feeder).
z
Paper weight: 41 to 209 g/m
2
(11 to 56 lb)
z
Variance in document lengths: 1% or less
z
Do not punch holes within 35 mm (1.38 in.) over the center of the
document. See Fig.1.
z
Do not attach other documents within 35 mm (1.38 in.) over the
center of the document. See Fig.1.

the pick roller width.
