A.5 Multifeed Detection Conditions
There are three multifeed detection modes: document layer, document length, and both
document layer and length.
The following conditions must be satisfied in each of these detection modes.
Detection by Layer
 Set sheets of the same weight in the ADF paper chute for a series of scans.
 Paper weight: 40 to 209 g/m
2
(11 to 56 lb)
 Punched holes are not allowed anywhere in the shaded column located in the
middle of the document with a width of 25 mm (0.98 in.) on either side within the
column. (*)
 Do not glue any other paper anywhere in the shaded column located in the middle
of the document with a width of 25 mm (0.98 in.) on either side within the column.
(*)
(*): Refer to "A.4 Area not to be Perforated or Affixed with Other Papers" (page 398) .
Detection by Length
 Set sheets of the same length in the ADF paper chute for a series of scans.
 Document length deviation: 1% or less
 Punched holes are not allowed anywhere in the shaded column located in the
middle of the document with a width of 25 mm (0.98 in.) on either side within the
column. (*)
(*): Refer to "A.4 Area not to be Perforated or Affixed with Other Papers" (page 398) .
Detection by both Layer and Length
 Set sheets of the same weight and length in the ADF paper chute for a series of
scans.
 Paper weight: 40 to 209 g/m
2
(11 to 56 lb)
 Document length deviation: 1% or less
 Punched holes are not allowed anywhere in the shaded column located in the
middle of the document with a width of 25 mm (0.98 in.) on either side within the
column. (*)
 Do not glue any other paper anywhere in the shaded column located in the middle
of the document with a width of 25 mm (0.98 in.) on either side within the column.
(*)
(*): Refer to "A.4 Area not to be Perforated or Affixed with Other Papers" (page 398) .
ATTENTION
 Multifeed detection by layer will always mis-detect thick paper as a multifeed error. To avoid
this, disable the intelligent multifeed detection mode or the multifeed detection.
 Multifeed detection rate may decrease depending on the document condition.
 Multifeed may not be detected for the top and bottom 30 mm of a document.
