Drive gear for extended drive shaft
A cartridge drive gear assembly for holding a drum coupling includes a drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes at least two voids disposed on opposing sides of the inner projections, and at least one slot disposed in the inner surface
1. A working end of a drive shaft of an imaging cartridge, the working end adapted to engage a printer drive mechanism, the working end comprising:
a plurality of arms,
wherein the arms are adapted to assume a closed position when the imaging cartridge is installed in a printer;
wherein the arms are adapted to open and slide over the printer drive mechanism as the imaging cartridge is installed in the printer.
2. The working end of claim 1 wherein the arms assume a closed position due to spring tension.
3. The working end of claim 1 wherein the arms assume a closed position due to spring tension applied to each arm.
4. The working end of claim 1 wherein when the arms are in the closed position, the arms engage the printer drive mechanism.
5. The working end of claim 1 wherein the arms comprise a plurality of claw-type arms.
6. The working end of claim 1 wherein the arms comprise a spring mechanism.
7. A working end of a cartridge drive shaft adapted to transmit rotational force from an imaging device to an imaging cartridge comprising:
a plurality of arms extending from an end portion of the cartridge gear shaft, the arms movable from a closed position to an open position as the imaging cartridge is inserted into the imaging device.
8. The working end of claim 7 wherein the arms assume a closed position due to spring tension.
9. The working end of claim 7 wherein the arms assume a closed position due to spring tension applied to each arm.
10. A working end of a cartridge drive shaft adapted to transmit rotational force from an imaging device to an imaging cartridge comprising:
a plurality of arms extending from an end portion of the cartridge gear shaft, the arms movable from a closed position to an open position as a force is applied to the arms.
11. The working end of claim 10 wherein the arms assume a closed position due to spring tension.
12. The working end of claim 10 wherein the arms assume a closed position due to spring tension applied to each arm.
