Claims
- 1. A toner module for use in an electrophotographic print engine comprising:
- elongated decorator means including a decorator core and a moveable endless outer sleeve mounted for rotation around said decorator core, said decorator core having a magnetic portion and a nonmagnetic portion;
- means for selectively securing said toner module within said print engine for printing and for alternatively removing said toner module from said print engine for loading and unloading;
- means for selectively rotating said decorator core of said decorator means between two positions, a first position where said nonmagnetic portion is at a lowest portion of said decorator roller for unloading and a second position where said magnetic portion is at said lowest position of said decorator roller for printing and loading;
- means for selectively moving said outer sleeve of said decorator means about said decorator core; and
- means for attaching a first container for loading and a second container for unloading, said first container containing new developer and attachable to said toner module adjacent to said lowest portion of said decorator roller, and said second container for receiving developer and attachable to said toner module adjacent to said lowest portion of said decorator roller.
- 2. A toner module for use in an electrophotographic print engine as recited in claim 1 further comprising;
- a mixing roller having a longitudinal axis and including an outer sleeve and a mixer core, said mixer core having a magnetic portion and a nonmagnetic portion, said longitudinal axis of said mixing roller located above and parallel to said longitudinal axis of said decorator roller;
- means for selectively rotating said outer sleeve of said mixing roller so that said developer passes over said non-magnetized portion of said mixer core and falls off said outer sleeve of said mixing roller onto said decorator roller.
- 3. A toner module for use in an electrophotographic print engine as recited in claim 2 wherein:
- said means for rotating said decorator core is manually operable.
- 4. A toner module for use in an electrophotographic print engine as recited in claim 1, further comprising:
- a mixing roller having a longitudinal axis and including an outer sleeve and a core, said core having a magnetic portion and a nonmagnetic portion, said longitudinal axis with said mixing roller located above and parallel to said longitudinal axis of said decorator roller;
- means for selectively rotating said outer sleeve of said mixing roller so that said developer passes over said magnetized portion of said core and is pulled further up into said toner module.
- 5. A toner module for use in an electrophotographic print engine as recited in claim 1 wherein:
- said means for rotating said decorator core is manually operable.
TECHNICAL FIELD
The present invention relates to toner modules for use in electrophotographic print engines, and more particularly, is a toner module which provides for an improved method of removing and replacing developer. The application is a continuation-in-part of U.S. Application Ser. No. 791,218, filed Oct. 25, 1985, entitled "Improved Print Engine For Color Electrophotography".
