Abstract
A method for removing carrier buildup in a slotted scavenger electrode in a printer comprising magnetically attracting the carrier toward the slot, blocking the slot with a movable flap for preventing toner dust from traveling through the slot, opening the movable flap for allowing the carrier to travel through the slot and return to the developer station, then reclosing the movable flap.
Claims20
A method for removing a buildup of a carrier on an electrode comprising:
- providing a slotted scavenger electrode for collecting the carrier;
- magnetically directing the carrier toward the slot in the scavenger electrode;
- and
- blocking the slot with a flexible flap, including accumulating the buildup to a volume sufficient for flexing open the flap, via the step of magnetically directing, thereby allowing the carrier to travel through the slot.

A method for removing a buildup of a carrier on an electrode comprising:
- providing a slotted scavenger electrode for collecting the carrier;
- magnetically attracting the carrier in a first direction toward the slot in the scavenger electrode;
- blocking the slot with a movable flap for preventing toner dust from traveling through the slot in a second direction and for temporarily preventing the carrier from traveling through the slot in the first direction;
- and
- opening the movable flap including unblocking the slot and including allowing the carrier to travel through the slot via the step of magnetically attracting the carrier.
