6.2 Clearing Paper Jams

Occasionally, paper can be jammed during a print job. Some of the causes include:

• The tray is loaded improperly or overfilled.

• The tray has been pulled out during a print job.

• The front cover has been opened during a print job.

• Paper was used that does not meet paper specifications.

• Paper that is outside of the supported size range was used.

If a paper jam occurs an error message appears in the LCD display. Find and remove the jammed paper.
If you don't see the paper, open the covers.
Do not use a tweezers, pincers or other metal tools when clearing a paper jam.
This could damage the internal mechanism causing print quality problems or possibly electrical shock.

Fault Clearance

When a fault occurs, check the Status Map on the Control Panel. A green blanking LED identifies
the problem area:
