Cleaning The Drum Unit - Brother MFC-9660 Owner's Manual

Cleaning the Drum Unit

We recommend you place the drum unit on a drop cloth or large piece of disposable paper to avoid
spilling and scattering toner.

Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left
several times.
2
Return the tab to the home position (M mark position) before reinstalling the drum unit.
If you do not position the tab at the home position, printed pages may have
vertical stripes.
