Abstract: Provided is a printer cartridge having a resilient pliable body. The resilient pliable body of the printer cartridge conforms to obstructions located in different positions inside the printer cartridge receiving cavity of different models and brands of printers. When the resilient pliable front of the printer cartridge contacts an obstruction in the cartridge receiving cavity of a printer, it is displaced in that area so that it is not an obstruction any longer, allowing the printer cartridge to fit and operate in multiple brands and families of printers.

Abstract: Provided is a method of orienting a printer chip to enable interoperation between the printer chip and more than one type of printer. The printer chip has a plurality of sets of contacts, each set of contacts capable of interoperation with a different type of printer, cartridge, or photoconductor unit. The chip is installed on the cartridge with the chosen set of contacts oriented to mate with the electrical contacts in the printer cartridge receiving cavity of the printer. The result is a printer chip that can be installed on a printer cartridge or photoconductor unit in a plurality of orientations in order to allow the printer cartridge or photoconductor unit to interoperate with a plurality of types of printers, or allow a plurality of types of printer cartridges or photoconductor units to interoperate with a printer.

Abstract: A process roller for use with an imagining cartridge, the process roller including sealing surfaces located at its distal ends. As the process roller rotates, the sealing surfaces of the process roller are sufficiently flexible to conform to the inner side walls of the imaging cartridge, thereby sealing the printing agent inside the imaging cartridge at the distal ends of the process roller.

Abstract: An imaging cartridge contains a wastebin and a hopper connected to the wastebin. A flat mounting surface on the wastebin receives a circuit board. A microswitch actuating tab is formed on the body of the imaging cartridge. A hopper is connected to the wastebin in a manner such that the hopper is supported entirely by the wastebin when the imaging cartridge is installed in the imaging cartridge receiving cavity of the imaging machine. The hopper is void of any protrusions adapted to rest on a supporting member in the imaging cartridge receiving cavity of the imaging machine.

Abstract: Provided is a printer cartridge equipped with a magnetic wastebin-hopper coupling. A combination of magnets and magnetically attractive materials are mounted on the wastebin assembly (or photoconductor unit) and hopper assembly of the printer cartridge in order to bias the two assemblies together. This allows an end user to remove the hopper assembly from the wastebin assembly (or photoconductor unit) and replace the expelled hopper assembly without having to latch or unlatch any mechanisms.

Abstract: Provided is an improved drive mechanism for an imaging machine. At least one external ramp is disposed along the outer perimeter of the drive dog whereby a tooth of the imaging machine drive mechanism is centered and directed into the drive dog seat. The leading edge of the drive dog seat contacts the base of the imaging machine drive mechanism thus making full contact between the drive dog seat and the imaging machine drive mechanism tooth.

Abstract: Provided is an improved drive mechanism for an imaging machine. At least one internal ramp radiates from the center of the drive dog whereby a tooth of the imaging machine drive mechanism is centered and directed into the drive dog seat. The leading edge of the drive dog seat contacts the base of the imaging machine drive mechanism thus making full contact between the drive dog seat and the imaging machine drive mechanism tooth.

Abstract: An imaging cartridge, for use in an imaging machine, has a handle that centers a user's hand to the center of the cartridge when inserting or removing the cartridge from the imaging machine. Planar members on the cartridge are guided by slots in the imaging machine for smooth insertion of the cartridge into the imaging machine.

Abstract: Provided is an imaging cartridge with an improved set of electrical contacts to make connection between the imaging components of the cartridge and an imaging machine. At least one electrically conductive contact point is disposed on a wall of the cartridge and a conductive element makes an electrical connection between the electrically conductive contact point and the imaging component.

Abstract: Provided is an improved drive mechanism for an imaging machine. A tapered surface is disposed outboard of the drive dog seat whereby a tooth of the imaging machine drive mechanism is centered and directed into the drive dog seat. The leading edge of the drive dog seat contacts the base of the imaging machine drive mechanism thus making full contact between the drive dog seat and the imaging machine drive mechanism tooth.

Abstract: Provided is an improved drive mechanism for an imaging machine. A tapered outboard tooth guide is disposed along the circumference of the drive dog and at least one tapered radius tooth guide is adjacent the tapered outboard tooth guide whereby a tooth of the imaging machine drive mechanism is centered and directed into the drive dog seat. The leading edge of the drive dog seat contacts the base of the imaging machine drive mechanism thus making full contact between the drive dog seat and the imaging machine drive mechanism tooth.

Abstract: Provided is an imaging cartridge with a universal body sculpted to mate with the imaging cartridge-receiving cavity of a plurality of imaging machine models. The universal body of the imaging cartridge enables the cartridge to be used with imaging machines made by different manufacturers, and different imaging machine models made by a common manufacturer. A plurality of recesses is formed in the leading end of the imaging cartridge body that accepts protuberances in an imaging machine's cartridge-receiving cavity and enables the cartridge to mate with a plurality of printers.
