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.
For documents that are loaded, the following conditions are required for overlapped documents to be detected accurately.
Paper weight: 50 to 209 g/m2 (13.4 to 56 lb) (0.06 to 0.26 mm)
Do not punch holes within 80 mm (3.15 in.) over the center of the document.
Refer to Fig. 1 in Area Not to Be Perforated.
Do not attach other documents with glue or other adhesive within 80 mm (3.15 in.) over the center of the document.
Refer to Fig. 1 in Area Not to Be Perforated.
The above condition applies when the document is set to the center of the pick roller width.
Scanning a thick document such as a plastic card will always be falsely detected as overlapped documents.
In such a case, disable the setting in the image scanning application or scanner driver so that overlapped documents are not detected, and then try scanning again.
The accuracy of detection for overlapped documents may drop depending on the document type.
Overlapping cannot be detected for the top 30 mm (1.18 in.) of a document in the feeding direction.
