disposable paper to avoid spilling and scattering toner.

Carefully turn the drum
unit upside down.

Clean the primary corona
wire inside the drum unit
by gently sliding the tab
from right to left several
times.

Return the tab to the home
position ( ▼ ) before
reinstalling the drum unit.

Caution

If you do not position the tab at the home position, printed pages may have
vertical stripes.
