4-8 Maintenance
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.
Cleaning the Paper Transfer Unit
Print problems such as soiling of the reverse side of printed pages may
occur if the paper transfer unit becomes dirty. To clean the paper transfer
unit, you must use the cleaning cloth.
