Cleaning The Drum Unit - Brother Backup Battery 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.
1
Turn the drum unit upside down carefully.
2
Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left
several times.
3
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.
4
Install the drum unit into the machine. (See Replacing the Drum Unit, page 126.)
