Clearing Jams
This section describes how to remove jammed paper.
Removing Jammed Paper from Inside the Machine
When print media jams inside the machine, the LCD displays .
CAUTION
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.
NOTE
When removing jammed paper from inside the machine, take care not to allow the toner 
on the jammed 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 front cover. 
2Remove the cartridge.
IMPORTANT
•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 the parts inside the 
machine.
•To avoid possible damage to the machine, do not touch the pins (A) near the left end of 
the transfer roller (B).
•When removing the jammed paper, do not touch the transfer roller as its surface is very 
delicate and susceptible to finger oil and scratches, which may lead to print deterioration.

cartridge in its original protective bag or wrap it with a thick cloth to prevent exposure to 
light.
3Open the face up cover (A) and push down the green paper 
release levers (B) on both sides of the face up paper output.
4Hold both sides of the jammed paper and carefully move it inward, 
then gently pull it out.

6If the leading edge of the paper is visible but has not entered the 
imaging area, pull the paper forwards and roll it inwards.
IMPORTANT
•Do not pull the jammed paper forward from the cassette. It may cause a machine 
malfunction.
•Do not pull the jammed paper upward; the toner on the paper will stain the machine and 
cause a permanent reduction in print quality.

12Push the paper release levers back to their original position and 
close the face up cover.
IMPORTANT
•Be sure to push 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.

IMPORTANT
After you replace the cartridge and close the front 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 pushed back to their original position, and check to see 
that jammed paper is not left in the machine.
14Insert the cassette to the machine.
Removing Jammed Paper from the ADF

LCD Messages
The following messages are displayed in the LCD when the machine performs a 
function or if it encounters an error.
This section describes the general messages and those related to copy and print 
functions. For the messages related to fax functions, see Chapter 7, 
“Troubleshooting,” in the Facsimile Guide.
ADJUSTING 
WAITING TO SCAN
Cause The machine is not ready for copying because you have just connected the 
power cord to the machine.
Remedy Wait for a while. The machine cannot scan documents for copying immediately 
after the power cord is connected.
CHECK DOCUMENT
Cause 1 There is a paper jam in the ADF.
Remedy Remove the document you are trying to copy in the ADF. (See “Removing 
Jammed Paper from the ADF,” on p. 9-7.)
Make sure that the document is not too long or too short. (See “Document 
Requirements,” on p. 3-1.)
Cause 2 The ADF roller rotates without feeding documents.
Remedy Fan the edge that will feed into the machine first, then tap the edge of multiple 
page documents on a flat surface to even the stack.
CHECK PAPER SIZE
Cause The size of the paper in the cassette or multi-purpose feeder is different from 
that of the paper specified in  of the Menu.
Remedy Load the correct paper size or change  in  
of the Menu. (See“Loading Paper,” on p. 2-3, or “Specifying the Paper Size,” on 
p. 2-10.)
Then reset the machine by opening the front cover and then closing it.
