To access the pick roller, reach into the media tray slot.  
Scrub the bottom surface of the pick roller thoroughly.  

Replace the upper media tray in the printer.

Cleaning the separator pad

Remove the upper media tray from the printer.

Gently wipe the separator pad using an alcohol-soaked cloth. 

Inspect the separator pad for damage to the metal edge; it should be free of dents and 
lie flat against the rubber surface.  If any damage is seen, the separator pad should be 
replaced (part number:  116-0838-00).
