摘要： Toner (5) is measured in a toner cartridge (1) by compressing the air in the upper part (7) of the toner hopper (3). The result of the compression is observed by a diaphragm (13) or, alternatively, by a pressure transducer (25). The volume of air is inversely proportional to the resonant frequency of diaphragm (13) or the pressure at pressure transducer (25). This is converted by control system (23) using direct equations or table look-up of empirical data. The diaphragm (13) carries a magnet (15), which is driven by coil (19) from the imaging device and then frequency of current induced by magnet (15) is then sensed by coil (19). Uneven toner piling is not a significant factor in the results measured.

摘要： An improved electrophotographic (EP) printer is provided having a detachable process cartridge that contains a non-volatile memory device, which is an EPROM that cannot be erased after a bit is burned. A "toner wheel" mounted to the exterior of the toner reservoir of the process cartridge provides, in conjunction with an optoelectronic sensor, an electrical signal that the printer receives and uses to determine toner usage. A toner "gas-gauge" is created which uses "bucket levels" as discrete steps to indicate how much of the measured physical toner material actually remains within the toner reservoir. After a given amount of toner material has been dispensed through the developer unit, one of the bits of the EPROM memory device is irreversibly burned, thereby providing a permanent record on the process cartridge of a certain amount of toner usage. As with a normal automobile gas gauge, the toner gas-gauge reading should never increase unless the amount of toner material inside the toner reservoir has increased. Once the bucket level transitions begin to occur for the toner gas-gauge, the printer becomes aware that a majority of the toner material has been expended from inside the toner reservoir. If the number of bucket gradation levels then increases by more than the hysteresis amount, then the printer will "lock out" the operation of a non-reusable process cartridge. When the lock-out mode occurs, a particular bit is burned on the EPROM mounted to the cleaner housing of the process cartridge. This ensures that this particular process cartridge cannot be removed, then simply placed back into the same (or a different) printer, and then begin supplying toner to a printer. Certain important "machine data" also can be stored in the EPROM memory device on the process cartridge of the present invention. The present invention is also able to declare the "end-of-life" of a process cartridge when the gas-gauge toner sensor is not functional (such as when it has been tampered with).

摘要： A waste toner removal device for transporting toner from a photoconductive drum within an image-forming apparatus. The invention includes a waste toner reservoir having outer walls forming an interior chamber for housing toner removed from the photoconductive drum. An opening is positioned within the outer walls into the interior chamber forming an upper chamber section extending above the opening and a lower chamber section extending below the opening. An auger extends along the photoconductive drum and unobstructed into the opening of the waste toner reservoir. The auger includes helical blades extending outward for moving the toner from the photoconductive drum into the waste toner reservoir. A pumping cylinder having a generally cylindrical shape extends around the auger adjacent to the waste toner reservoir. The diameter of the pumping cylinder is approximately equal to the helical blades wherein rotation of the auger creates a pumping action for moving toner into the said upper and lower chamber sections.

摘要： A toner cartridge (1) contains a photoconductive drum (49) having a central shaft (47). Gear (145) turns with the drum and has a stud (602). A coil spring (604) is mounted on the stud to form a spring clutch which is unwound by the rotation of the drum during imaging. Alternatively, a flat frictional surface is pressed against the side wall (600b) of the gear. Both contact areas have a light grease. The drag forces provide accurate, smooth operation during imaging.
