If black streaks appear with printing, the 
fuser roller in the main unit may be dirty. 
Should this occur, clean the fusing roller 
in the following procedure. The roller 
should also be cleaned each time the 
toner cartridge is replaced. Load a sheet 
of blank LTR paper into the multi-purpose 
tray and start cleaning.

Cleaning the roller takes approximately 130 
seconds.
