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:
Techniques for remanufacturing a toner cartridge include providing the toner cartridge comprising an end plate secured to an end of the toner cartridge, removing the end plate from the toner cartridge, attaching an anchoring fixture to the end of the toner cartridge, and securing the end plate to the anchoring fixture of the toner cartridge.
Abstract:
Techniques are provided for modifying a printer cartridge intended to operate in one type of printer to operate in another type of printer. In one aspect, a method of modifying a toner cartridge intended for operation in a first type of printer to operate in a second type of printer includes removing at least a portion of an old laser shutter fin attached to the toner cartridge at a first location, and attaching a new laser shutter fin to the toner cartridge at a second location, with second location differing from the first location. The old laser shutter fin was positioned to engage a laser shutter of the first type of printer, and the new laser shutter is positioned to engage a laser shutter of the second type of printer. In another aspect, the method may include attaching a chip mounting patch to the toner cartridge, and attaching a computer chip to the chip mounting patch, with the computer chip being compatible with the second type of printer. In another aspect, the method includes replacing a first type of transfer gear of the toner cartridge with a second type of transfer gear, with first type of transfer gear for operation with the first type of printer and said second type of transfer gear for operation.
Abstract:
A throttle device comprises a tubular outer sleeve having a plurality of outer sleeve circumferential grooves formed on an outer sleeve inner surface and intersecting a plurality of outer sleeve axial grooves formed on an outer sleeve outer surface to form outer sleeve orifices. Also included is a tubular inner sleeve concentrically disposed within the outer sleeve and having a plurality of inner sleeve circumferential grooves formed on an inner sleeve inner surface. A plurality of inner sleeve axial grooves are formed on the inner sleeve outer surface and intersect the inner sleeve circumferential grooves to form inner sleeve orifices. The offset inner and outer sleeve orifices define tortuous flow paths wherein fluid flows into the outer sleeve axial grooves, through the outer sleeve orifices, through the outer sleeve circumferential grooves, through the inner sleeve axial grooves, through the inner sleeve orifices before exiting the inner sleeve circumferential grooves.
Abstract:
A cartridge chip for use with an imaging cartridge installed in an imaging device, the cartridge chip comprising a memory element storing imaging cartridge data, and a controller for controlling the operation of the cartridge chip and determining if the imaging device is a first type of imaging device or a second type of imaging device, the controller for operating the cartridge chip in a first mode of operation if the imaging device is the first type of imaging device, the controller for operating the cartridge chip in a second mode of operation if the imaging device is the second type of imaging device.
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:
Provided is a servovalve system having a fail safe apparatus adapted for switching the servovalve system between an operating position and a fail safe position. The servovalve system comprises a housing having a housing bore and a housing chamber, a spool moveably disposed within the housing, and a stepper motor connected to the spool and configured to vary the spool position for manipulating the fluid flowing within a fluid circuit when the servovalve system is placed in the operating position. A rotary-linear converter converts rotational motion of the stepper motor into axial motion of the spool. The fail safe apparatus includes a piston slidably sealed within the housing chamber and mechanically coupled to the rotary-linear converter. The piston is operative to move the spool from the operating position to the fail safe position upon a loss of fluid pressure in the housing chamber.
Abstract:
A valve assembly comprising a rotary closure element which defines an axis of rotation and is selectively movable between a fully open position and a fully closed position. Mounted to and movable with the rotary closure element is an impedance assembly. The impedance assembly defines an inflow end and an outflow end, and comprises a plurality of fluid passageways of varying noise attenuating capability which extend from the inflow end to the outflow end. Also partially defined by the impedance assembly is a flow opening which extends from the inflow end to the outflow end. A retainer bracket is disposed within the flow opening and is cooperatively engaged to both the closure element and the impedance assembly.
Abstract:
In the toner cartridge recycling and remanufacturing industry, used xerographic products are reconditioned, repaired, and some are refilled with toner. Part of the refurbishment process is the replacing of used and worn components, including an electronic circuit, which has been spent. The electronic circuit is a critical component of the replaceable consumable unit and is used by the printer to store information used in the operation of the printer. Information stored in this electronic circuit relates to how much toner is remaining, the cartridge type, operating characteristics, and so forth. Some of these circuits have been designed for a one-time use application. For example, once the printer has determined that all of the usable toner has been consumed, the printer will essentially turn off the circuit in a replaceable consumable unit and the replaceable consumable unit will no longer function. In the remanufacturing process, a secondary electronic circuit can be attached to this non-functioning circuit in order to allow the replaceable consumable unit to operate once more. The nature of the present invention is directed at the process of repairing this non-functioning circuit and the resulting repaired unit.
