This section describes how to remove jammed paper.
Removing Jammed Paper from Inside the Main Unit
When print media jams inside the main unit, the LCD displays REC. PAPER JAM.
• There are some areas inside the machine and cartridge which are subject to high voltages and
high temperatures. Take adequate precaution when performing internal inspections to avoid
burns or electrical shock.
• When removing jammed copy paper from inside the machine, take care not to allow the toner on the
jammed copy paper to come into contact with your hands or clothing. If they become dirty, wash them
immediately with cold water. Washing with warm water will set the toner and make it impossible to
remove the toner stains.

1Open the right cover.  If there is paper left
in the cassette or on the output tray, remove
it first.
2Remove the cartridge.
• Dont expose the cartridge to light for more
than 5 minutes. If necessary, put the
cartridge in its original protective bag or
wrap it with a thick cloth to prevent
exposure to light.• Remove watches and any bracelets or rings
when touching the inside of the machine.
These items might be damaged if they
come into contact with parts of inside the
machine.
• When removing the jammed paper, do not
touch the transfer roller (shaded part) as its
surface is very delicate and susceptible to
finger oil and scratches, which may lead to
print deterioration.
• To avoid possible damage to the printer, do
not touch the pins near the left end of the
transfer roller.

3Hold both sides of the jammed paper and
carefully move it inward, then gently pull it
out.
• Do not pull the jammed paper upward; the
toner on the paper will stain the printer and
cause a permanent reduction in print quality.
4Roll the trailing edge of the paper so that
the printed surface is on the inside of the
roll, then gently pull the rolled up paper out
of the machine.
5If the leading edge of the paper is visible
but has not entered the imaging area, pull
the paper forwards and roll it inwards.
• Do not pull the jammed paper upward; the
toner on the paper will stain the printer and
cause a permanent reduction in print quality.
6Open the left cover and push down the
green paper release levers on the right and
left.

7Gently pull the jammed paper between the
output rollers until the leading edge
emerges from the machine.
8Carefully pull the jammed paper through
the rollers and out of the machine.
9Carefully pull the jammed paper straight
out.
• If the jammed paper is badly folded, similar to the
folds of an accordion, ease the jammed paper
loose and then pull it out of the printer.
10Place the paper release levers back to their
original position, and close the left cover.
• Be sure to place the paper release levers
back to their original position.  If the levers
are left pushed down, the paper jam error
will not be resolved.  Never push down the
paper release levers while printing. This
could result in damage to the fixing
assembly.
11Return the cartridge back into the machine,
then close the right cover.
• For details, refer to “Replacing the Cartridge” 
(→p. 7-6).
• After you replace the cartridge and close the
right cover, the machine should be ready for
operating. If the machine returns to the
ready state for operating, troubleshooting
has been successful. If the machine does not
return to the ready state for operating,
confirm that the paper release levers are
placed back to their original position, and
check to see that paper is not left in the
machine.
12For jams in the multi-purpose tray, remove
the multi-purpose tray. Hold the both sides
of the jammed paper and pull it straight up
and out from the machine. Then, set the
multi-purpose tray back on top of the
cassette.

Troubleshooting
❚Paper does not feed correctly.
The cassette or multi-purpose tray may contain too many sheets.
• Make sure the paper stack in the cassette or the paper in the multi-purpose tray does not exceed the capacity of
the cassette or multi-purpose tray. (→ pp. 2-3 to 2-7)
Paper may not be loaded correctly.
• Make sure the paper stack in the cassette or the paper in the multi-purpose tray is loaded properly, and that the
slide guides are adjusted correctly. (→ pp. 2-3 to 2-7)
❚Paper feeds skewed. (Printing is skewed.)
Paper may not be loaded correctly.
• Make sure the paper stack in the cassette is loaded properly, and that the slide guides are adjusted correctly.
(→ pp. 2-3 to 2-7)
• Make sure the paper exit path is clear.
❚Multiple sheets feed into the machine at the same time.
Paper may not be loaded correctly.
• Make sure the paper stack in the cassette is loaded properly, and that the slide guides are adjusted correctly. (→
pp. 2-3 to 2-7)
Sheets of paper may be sticking together.
• Be sure to fan the paper stack before loading it in the cassette. This keeps the sheets of paper from sticking
together.
The cassette may contain too many sheets.
• Make sure the paper stack in the cassette does not exceed the capacity of the cassette. (→ pp. 2-3 to 2-7)
• Do not force the paper stack into the cassette.
Different types of paper may be loaded in the cassette.
• Load only one type of paper.
• Make sure you load paper that meets the paper requirements for the machine. (→Chapter 2)
❚Transparencies do not feed correctly.
The transparencies are loaded in the cassette.
• Do not load transparencies in the cassette. Load them in the multi-purpose tray.
The transparencies may not be loaded in the multi-purpose tray correctly.
• Make sure they are loaded properly (→ p. 2-5). The transparencies should be loaded one by one in the multi-
purpose tray.
The transparencies for color copiers may be loaded in the multi-purpose tray.
• Do not use any transparencies for color copiers. They will cause a paper jam. Please use transparencies
recommended by Canon.
❚Paper feeds curled.
Unacceptable paper is loaded.
• Load proper paper in the cassette or multi-purpose tray. (→ Chapter 2)
• Select TRANSPARENCYin the PAPER TYPEof the Additional Functions. (→ p. 4-4)
