Cleaning the drum unit
We recommend placing the drum unit and toner cartridge assembly
on a cloth or large disposable paper to avoid spilling and scattering
toner.

Clean the primary corona wire inside the drum unit by gently
sliding the blue tab from right to left several times.
2
Return the blue tab and snap it into the Home position (▼).
Caution
If the blue tab is not at Home position (▼), printed pages may have
vertical stripes.

Reinstall the drum unit and toner cartridge assembly into the
DCP.
(See Replacing the drum unit on page 14-30.)
