Abstract:
Electronic systems, such as printing systems, often use components that have integral memory. The integral memory can be used to store information about the component. In some printing systems this memory includes a portion that stores a value indicative of a print yield. Disclosed is a method and system for allowing the memory to have data indicative of an increased print yield.
Abstract:
An interior member of a print cartridge gear including one or more slots in the interior member for receiving a pin, the one or more slots including a first portion extending from a distal end of the interior member towards a base end of the interior member, the one or more slots including a second portion that extends horizontally outward.

Abstract:
A method of operating a cartridge chip installed in an imaging device includes: causing, by the cartridge chip, the imaging device to enter an error condition; monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and operating, based on the timing or sequence of the communication signals received from the imaging device during at least a portion of the error condition, in a first mode of operation compatible with a first type of imaging device not having a list of banned serial numbers or in a second mode of operation compatible with a second type of imaging device having a list of banned serial numbers.
Abstract:
Techniques for modifying a toner cartridge intended to operate with a first type of imaging device to operate in a second type of imaging device. The toner cartridge includes a drum shutter connected to a waste bin, with the drum shutter including first and second shutter arms. A method of modifying the toner cartridge intended for operation in the first type of imaging device to operate in a second type of imaging device includes removing a portion of the first shutter arm. In another aspect, the method includes removing a portion of the waste bin adjacent to the first shutter arm. In another aspect, the method includes removing a second portion of the waste bin to form a hole in the waste bin and attaching a chip mounting patch to the waste bin to fill the hole. A computer chip may be attached to the chip mounting patch.
Abstract:
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.
Abstract:
A drive gear for a generally cylindrical imaging component. The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and lobes extending longitudinally outward from the end surface.
Abstract:
A method of remanufacturing an imaging cartridge comprising a toner hopper having a toner bag and not having a seal port, the method comprising forming a seal port in the toner hopper; disposing a replacement toner container in the toner hopper, the replacement toner container including a removable seal having a seal tail; inserting a portion of the seal tail through the seal port and repairing a broken doctor blade contact
Abstract:
Many devices, such as printers, work with one or more removable unit. Often, the removable units have an electronic circuit that used to communicate with the device. It may be desirable to provide a replacement unit in these devices. The replacement unit must include an electronic circuit that is able to communicate with the original device. Disclosed is a method and apparatus where a replacement unit is provided with a new electronic circuit and a used electronic circuit. The new electronic circuit is electrically connected to the used electronic circuit and uses the used electronic circuit to facilitate communication with the host device.
