Troubleshooting

11-2

This section describes how to 
remove jammed paper. When error 
messages appear on the LCD display, 
see “LCD Messages,” on p. 11-12. 
For other troubles, see Chapter 10, 
“Troubleshooting,” in the Reference 
Guide, or Chapter 3, “Troubleshooting,” 
in the Scanner Driver Guide.
When <CHECK DOCUMENT>, <PAPER 
JAM> or <PAPER JAM/OPEN REAR 
COVER> appears on the LCD display, 
remove jammed paper from the machine 
first, then from the paper cassette or 
multi-purpose tray if necessary. Check 
the following if you experience repeated 
paper jams:

Fan and tap the paper stack on a 
flat surface before loading it in the 
machine.
Check that the paper you are using 
meets the requirements for use. (See 
“Paper Requirements,” on p. 2-9.)
Make sure you have removed any 
scraps of paper from the inside of the 
machine.

When removing jammed documents or paper, 
take care not to cut your hands on the edges of the 
document or paper.
When removing jammed paper or when inspecting 
the inside of the machine, do not allow necklaces, 
bracelets, or other metal objects to touch the 
inside of the machine, as this may result in burns or 
electrical shock.
If you tear the paper, remove any torn pieces to 
avoid further jams.
If loose toner comes into contact with your skin or 
clothing, wash with cold water. Warm water will set 
the toner.

Do not force a jammed document or paper out of 
the machine. Contact Canon Customer Care Center if 
needed.
