Clearing paper jams
Note
When removing paper that is jammed in the printer, if possible 
always pull the paper in the direction that it normally moves so 
as not to damage internal components. Always pull firmly and 
evenly; do not jerk the paper. If the paper tears, ensure that all 
fragments of paper are removed; otherwise a jam will occur 
again.
When a paper jam occurs, the Status  LED lights red. Open and close the 
front cover. The jammed paper automatically exit the printer. 
If the paper does not exit, check the display on the control panel. The 
message indicating the corresponding location of the paper jam 
appears. Refer to the table below to locate the paper jam and to clear it:

Tips for avoiding paper jams
By selecting the correct media types, most paper jams can be avoided. 
When a paper jam occurs, follow the steps outlined on page 9.1. 
•  Follow the procedures on page 5.5. Ensure that the adjustable guides 
are positioned correctly.
•  Do not overload the tray. Ensure  that the paper level is below the 
paper capacity mark on the inside wall of the tray.
•  Do not remove paper from the tray while your printer is printing.
•  Flex, fan, and straighten paper before loading. 
•  Do not use creased, damp, or highly curled paper.
•  Do not mix paper types in a tray.
•  Use only recommended print media. See 
page 5.1.
•  Ensure that the recommended print side of print media is facing down  in the tray, or facing up in the multi-purpose tray.
•  If paper jams occur frequently when you print on A5-sized paper:
Load the paper into the tray with the  long edge facing the front of the 
tray. 
In the printer properties window, set the page orientation to be rotated 
90 degrees. See the  Software Section.

Troubleshooting checklist
If the printer is not working properly,  consult the following checklist. If the 
printer does not pass a step, follow the corresponding troubleshooting 
suggestions.
ConditionSuggested solutions
