Cleaning for media tray jams 

If the printer incorrectly feeds paper or transparencies, or feeds more than one sheet at a 
time from the media tray, refer to Preventing media jams on page 50 before cleaning the 
printer.  If rollers are visibly dirty, perform the following cleaning procedures.     

Cleaning the media-pick roller

Remove the media tray from the printer.

Open the front cover.     

Remove the maintenance drawer (A) from the printer.   

Hot surfaces exist behind the upper paper-feed rollers.  To avoid 
personal injury during cleaning procedures, do not reach in 
behind the paper-feed rollers.
