Cleaning for ink smears or jams: paper-feed rollers

 

Clean the paper-feed rollers if media feeds improperly, or if prints have ink smears. 

 

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

 

Open the front cover.

 

Remove the maintenance drawer (A) from the printer.     

 

The upper paper-feed rollers are located above the slot for the maintenance drawer (A).  To clean 
these rollers:

 

Place a prepackaged alcohol-soaked wipe against each upper rubber roller, pressing to create 
pressure against the roller.

 

Use the thumbwheel to turn the upper rollers.  The upper rubber rollers should rotate 

 

 for each roller segment to ensure proper cleaning.  Scrub each roller 

thoroughly.

 

If the wipe becomes dirty, discard it and use another.  

 

To clean the middle rubber feed roller behind the metal plate:

 

Place a prepackaged alcohol-soaked wipe against the underside of each middle roller.

 

Using your hand, rotate the middle roller.
