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  
and .
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.

Remove 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.
  
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.
NOTE
 
Do not 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.

Roll the leading end of the paper outwards so that the printed 
surface is on the inside of the roll, then gently pull the rolled up 
paper out of the machine.

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 printer and 
cause a permanent reduction in print quality.

Open the face up cover and push down the green paper release 
levers on both sides of the face up paper output.

Carefully pull the jammed paper straight out through the rollers. 
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 machine. 
13
 
Push 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.

Insert the cartridge back into the machine, then close the front 
cover. 
For details, see Replacing the Cartridge, on p. 8-14.
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.
