Remove the document following the procedure below.
(1)If printing is in progress, press the Stop/Reset button.
(2)Turn off the machine.
(3)If a multi-page document is loaded, remove any pages other than the
jammed page from the ADF, then open the Document Feeder Cover.
(4)Raise the Paper Release Lever (A), then remove the jammed page from
under the roller to the Document Feeder Cover side.
(5)Pull out the jammed document from the ADF.
If the document cannot be pulled out with ease, follow the procedure in
"Document jams in the ADF (inner side)." on page 155.
(6)Press down the Paper Release Lever (A), close the Document Feeder
Cover, then turn on the machine.
When rescanning the document after clearing the error, rescan it from the
first page.
If you cannot remove the document or the document tears inside the machine,
or if the document jam error continues after removing the document, contact
your Canon service representative.
Note
The document may not feed properly depending on the media type, or your
environment, such as when the temperature and humidity are either too high or
too low.
In this case, reduce the number of document pages to approximately half of the
loading capacity. See "Original Document Requirements" on page 16.
If the document still jams, use the Platen Glass instead.
