Cleaning
Periodically clean the inside and outside of the printer with a soft cloth and small
vacuum cleaner when necessary.
Caution Do not touch the terminals of the image drums, the LED bar, and
the LED head connector block. Clean with alcohol wipe, if
necessary.
Cleaning the LED bar
The LED lens array must be cleaned when the printed paper has white lines or
irregular colors (such as a void or light printing) running vertically down of the
paper. Clean the lens with an alcohol wipe to clean the LED bar. (An alcohol
wipe always comes with the toner cartridge.)
Print the 100% Color Stripe 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.
Cleaning the pickup roller
When mispicks occur, clean the pickup roller.
Note The roller should be cleaned with a clean, dry, lint-free cloth if
debris is visible so the surface is not scratched.
