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, the On Line/Error LED on the control panel lights red. Find and remove the jammed paper. If you don’t see the paper, open the covers. Do not use a tweezers or a sharp metal tool when removing a jam. The covering of a metal part can be removed which can cause an electric leakage.
