Rigid agitator and shaft assembly
A toner cartridge includes a waste bin and hopper designed with a rigid agitator assembly. A non-yieldable agitator is mounted on a shaft whereby the rotation of the shaft results in the synchronous rotation of the agitator. As the shaft rotates, the agitator enters into, through, and out of engagement with the toner within said toner chamber.
1. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a toner chamber;
a shaft mounted for rotation within said toner chamber;
an agitator mounted on said shaft whereby the rotation of said shaft results in the synchronous rotation of said agitator into, through, and out of engagement with the toner within said toner chamber;
a light blocking wheel integral, and in non-yielding engagement, with a distal end of said shaft at a point external of said toner chamber whereby rotation of said shaft results in synchronous rotation of said light blocking wheel; and
a drive gear integral, and in non-yielding engagement, with a distal end of said shaft at a point external of said toner chamber whereby rotation of said drive gear results in synchronous rotation of said shaft.
2. The toner cartridge of claim 1 further comprising a home window disposed within said light blocking wheel.
3. The toner cartridge of claim 1 further comprising angled support members disposed between said agitator and said shaft.
4. The toner cartridge of claim 3 further comprising angled tooth members disposed along a toner engaging surface of said angled support members.
5. The toner cartridge of claim 1 further comprising straight support members disposed between said agitator and said shaft.
6. The toner cartridge of claim 5 further comprising angled tooth members disposed along a toner engaging surface of said straight support members.
7. The toner cartridge of claim 1 further comprising an ancillary agitator disposed at one end of said shaft.
