Procedures
Cleaning
Periodically clean the inside and outside of the printer with a soft cloth and toner
vacuum when necessary.
Contacts
Contacts can be cleaned with a standard pencil eraser or a soft brush and toner
vacuum cleaner.
Cleaning the LED Lens
Caution: Do not touch the terminals of the Drum Contacts, the LED
Head lens, or the LED Head connector block. Clean with
an alcohol wipe, if necessary.
The LED lens must be cleaned when the printed paper has white lines or irregular
colors (such as a void or light printing) running in the direction of paper travel or
process direction.
Clean the LED lens with an alcohol wipe. (An alcohol wipe always comes with the
replacement toner cartridge.)
Print the 100% Solid Fill Pattern. If a light or white stripe appears in any primary
color or a secondary color has an irregular color streak, clean the LED lens of the
affected color.
