Detack
After the toner image transfers to the surface of the paper, the Detack Saw (a thin
strip of metal that resembles a saw blade) applies a low voltage negative charge to
the back of the paper to neutralize the positive voltage that was applied to it by the
BTR. Once the positive voltage is neutralized, the paper strips releases easily from
the drum surface and continues along the paper path to the Fuser.
Clean
The Cleaning Blade removes any toner that remains on the drum after the transfer
process. The toner that the Cleaning Blade removes is collected inside the sealed
EP Cartridge. Toner that is reclaimed from the drum is not reused by the EP
Cartridge.
