Abstract:
Systems and methods of remanufacturing an imaging cartridge including the replacement an organic photo conductor (OPC) drum in the imaging cartridge having end caps which are fixedly secured to the waste bin or other portion of the toner cartridge. In one aspect, the method involves removing the existing OPC drum without detaching the end caps and installing a replacement OPC drum without disturbing the end caps.
Abstract:
Techniques are provided for repairing or remanufacturing a toner cartridge which includes a drum shutter and a toner cartridge body. The drum shutter includes a flexible covering portion attached to both an arm element and the toner cartridge body. The flexible covering portion is removed from the arm element and the toner cartridge. A replacement flexible covering portion is secured to the arm element. The replacement flexible covering portion is attached to the toner cartridge body.
Abstract:
A method of remanufacturing a replaceable consumable unit includes providing the replaceable consumable unit including a first electronic circuit, with the first electronic circuit being at least partially inoperable; providing a second electronic circuit; communicatively connecting the second electronic circuit to the first electronic circuit; and intercepting, by the second electronic circuit, signals sent by an imaging system to the first electronic circuit.
Abstract:
A method for modifying a process cartridge includes providing the process cartridge comprising a waste bin having physical characteristics. The method further includes altering the physical characteristics of the waste bin to form an altered process cartridge.
Abstract:
An electronic module for use in a printer consumable unit includes a first input and output (I/O) port adapted connected to an external contact, and a second I/O port connected to the external contact. Circuitry controls the electronic module and responds to read memory commands and write memory commands received through the external contact on the I/O ports. A memory stores data. A third port is connected to the external contact and adapted to source current. The circuitry is initially configured to send and receive data through the first I/O port. The circuitry tests the functionality of the first I/O port by directing the third port to source current and drive the external contact to a predetermined voltage, and read a voltage received by the first I/O port in response to sourced current. If the circuitry determines the first I/O port is not functioning correctly based on the read voltage, the circuitry will send and receive data through the second I/O port.
Abstract:
A method of remanufacturing an imaging cartridge comprising toner hopper not including a toner hopper access port comprises forming an access hole in a surface of the toner hopper, inserting toner into the toner hopper through the access hole, and adhering a hopper cap over the access hole to seal the access hole, the hopper cap comprising apparatus for facilitating removal of the hopper cap.
Abstract:
A remanufactured toner cartridge comprising a toner hopper, a developer roller housing, end caps holding the waste bin and developer roller in a fixed position with respect to each other, and a seal assembly attaching the toner hopper to the developer roller housing comprising a first gasket having a first side, a second side, and a gasket opening, a removable seal layer having a first side, a second side, a first end and a second end, said first side of the first gasket attached to a toner hopper sealing surface, the first side of the removable seal layer being attached to the second side of the first gasket, the removable seal layer covering the gasket opening, a tail of the removable seal layer attached to the second end of the removable seal layer, an electrical trace attached to the second side of the removable seal layer at the second end of the removable seal layer, a second gasket with a first side and a second side and a first end and a second end, the first side of the second gasket being attached to the second side of the first gasket except at the second end of the second gasket, the second side of the second gasket attached to the developer roller housing.
Abstract:
Techniques for remanufacturing an imaging cartridge include providing the imaging cartridge including a memory element storing cartridge usage data, reading from the memory element the cartridge usage data, analyzing the cartridge usage data to produce results, and determining, based on the results, if a component of the imaging cartridge needs to be replaced. A cartridge memory interface device includes processing circuitry adapted for reading cartridge usage data from a memory element of an imaging cartridge. The processing circuitry is further adapted for analyzing the cartridge usage data to produce results for determining if any components of the imaging cartridge need to be replaced. A user interface displays the results to a user.
Abstract:
A method for converting a process cartridge includes providing the process cartridge comprising a waste bin having physical characteristics. The process cartridge is suitable for use in a first type of printing device and not suitable for use in a second type of printing device. The method further includes altering the physical characteristics of the waste bin to form an altered process cartridge suitable for use in the second type of printing device.
