Conditions Required to Accurately Detect Overlapped Documents
(Multifeed)
Multifeed is an error that occurs when two or more sheets are overlapped and fed at once.
Overlapped documents are detected with the ultrasonic sensor or according to the difference in
length of the documents.
For documents that are loaded, the following conditions are required for overlapped documents
to be detected accurately.
Detecting Overlapped Documents with the Ultrasonic Sensor
● Paper weight: 40 to 209 g/m 2 (11 to 56 lb) (0.05 to 0.250 mm)
● Do not punch holes within 35 mm (1.38 in.) over the center of the document.
Refer to Fig. 1 in
Area Not to Be Perforated (page 96) .
● Do not attach other documents with glue or other adhesive within 50 mm (1.97 in.) over the
center of the document.
Refer to Fig. 2
Detecting Overlapped Documents according to the Difference in Length
● Load the documents of the same length in the ADF paper chute (feeder).
● Variation in document lengths: 1% or less
● Do not punch holes within 35 mm (1.38 in.) over the center of the document.
