Guides in the selected tray are not set to 
the appropriate position for the size 
paper loaded.

Move the guides in the tray to the correct position.

The paper has absorbed moisture due to 
high humidity.

Load paper from a fresh package.

Store paper in its original wrapper until you load it.

The

message remains 

after you remove the jammed 
paper. 

Clear paper from the entire paper path, and then

The page that jammed does not 
reprint after you clear the jam. 

Set 

Jam Recovery
