Clearing Paper Jams
Occasionally, paper can be jammed during a print job. Some of 
causes include:
• The tray is overfilled.
• The front cover has been opened during a print job.
• Paper that does not meet paper specifications has been used. 
See “Paper Specifications” on page 6.3.
• Paper that is outside of the supported size range has been 
used. See “Paper Specifications” on page 6.3.
If a paper jam occurs, the 
On Line/Error LED on the control 
panel lights red. Find and remove the jammed paper. If it is 
invisible, look inside the printer.
In the Paper Exit Area
Note: Paper jams in this area may result in loose toner on the 
page. If you get any toner on your clothes, wash them in cold 
water as hot water will set the toner into the fabric.
1If the paper jams as it exits to the output tray and a long 
portion of the paper is visible, pull the paper straight out.
When you pull the jammed paper, if there is resistance and 
the paper does not move immediately, stop pulling. 
Continue with the next step.

2 Open the top cover and the inner cover. 
Cautions: 
• When removing the jammed paper, be careful not to touch the 
heat roller (located underneath the inner cover). It is hot and 
could cause burns!
• The top and inner cover themselves may also be hot due to the 
heat roller. Allow the printer to cool before opening the covers.
3Loosen the paper if it is caught in the heat rollers. Then pull 
the paper gently out.
