Cleaning the Printer
The paper transfer unit should be cleaned each time the toner container
and waste toner box are replaced.
To maintain optimum print quality, it is also recommended that the inside
of the printer be cleaned once a month as well as when the toner
container is replaced.
It should also be cleaned if streaking or lines appear on printed copies, or
if printouts appear faint or blurred.
