Paper Feed Trouble
Paper Feed Trouble
If the document is not fed properly or the detection functions do not work
smoothly, remedy the problem by following the remedies described below.
Condition Paper jam has occurred.
Cause and remedy ● Check the document to see if the size and thickness of
the document are within the ranges supported by the
scanner, and to see if the quality of the document paper
is appropriate.
Refer to cautions on handling documents. (See “About
Documents” P. 42)
● Document slipping may be causing a paper feed error
(See “Paper Feed Adjustment” P. 36).
● The intermediate unit is not attached properly. Properly
attach the intermediate unit. (See “Attaching the
Intermediate Unit” P. 67)
● Dirty or worn rollers inside the scanner cause paper
jams.
Clean rollers if dirty (See “Cleaning the Scanning Glasses
and Rollers” P. 75).
Worn rollers must be replaced. Contact a Canon service
department.
Condition The document tray does not rise and you hear a
clicking sound.
Cause and remedy The weight of the loaded paper sometimes increases due to
the environment in which the document is stored. If this
happens, the weight of the paper will exceed the maximum
allowed stacked weight even if the number of stacked
sheets is below the maximum, and sometimes prevent the
document tray from rising. Reduce the number of document
sheets loaded on the document tray and scan the document
again. (See “Document Loading Precautions” P. 43)
Condition Double feed error occurs even though documents are
not being double-fed. (erroneous detection of double
feed)
Cause and remedy If the size and thickness of the paper on which the Function
Sheet is copied differs from that of the document to be
scanned when the Function Sheet is used, the scanner
erroneously judges this to be a double feed, and this error
occurs. If this happens, turn double feed detection OFF, and
scan the document again. Or, copy the Function Sheet on
paper of the same size and thickness as the document, and
use that copy.
