摘要： An improved printer is provided that predicts how many pages can be printed before the toner or ink cartridge becomes empty, and also predicts how much time remains before this toner or ink cartridge becomes empty. This prediction is based upon the previous printing history of the printer while using this particular toner cartridge. After measuring the quantity of toner left in the toner cartridge, the printer of the present invention will display the approximate quantity of toner remaining in the cartridge on a screen of a host computer that is connected to the printer, either directly or through a network. The monitor screen of the host computer can also display the predicted number of pages remaining, based on the printer's previous usage history as described above. The toner measuring device provides a "level change" output signal when the remaining toner passes through a predetermined gradation threshold, and depending upon the size of the toner cartridge and upon the time and date at which the level change was detected, the predicted number of pages remaining and the actual amount of toner remaining are more accurately updated upon reaching one of these predetermined gradation thresholds. As each gradation level transition occurs, the printer calculates a new value for the "pages per gradation" variable, and also calculates the number of pages that have been printed since the latest cartridge was installed in the printer, the number of pages printed since the last level or gradation change, and the number of pages or sheets printed between the last two level changes. The printer also can approximate the amount of toner used in printing a particular page of print media to create a Toner Tally for each printed page, which can be used to judge the amount of toner used for one print job and compare that to the amount of toner used for a second print job. The Toner Tally uses a combination hardware/software counter to count the number of "active" pels of each page for a print job.

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 method of reducing EMI when printing an image with a printer having a laser includes determining edge pels located near an edge of the image, determining interior pels located within the image and not edge pels, forming edge pels by operating the laser at a first duty cycle and forming at least a portion of a plurality of interior pels by operating the laser at a second duty cycle longer than the first duty cycle. Another aspect is a method of reducing EMI in a printer when forming a latent image on a photoconductive member by gating a light source ON and OFF, including the steps of identifying a first region near an edge of an image to be formed, the first region being formed by gating the light source at a first frequency; and identifying an interior region of the image to be formed, the interior region being formed by gating the light source at a second frequency lower than the first frequency.

摘要： Toner is conserved in printer (1) under operator control by changing the final modulation for each bit in a bit map depending on whether the bit is an edge bit or an internal bit in the character being printed. Since only the final modulation is affected, processing speed and efficiency are not degraded. The operator can select various degrees of internal gray and internal white. Some levels of gray may be satisfactory for some final correspondence.

摘要： A facsimile printer (1) in which sets of one or two pels contiguous to longer lines of such pels are reduced or eliminated. When reduced the smaller pels are positioned continuous to the longer line and are extended one pel on each side where the longer line exists. This reduces scanner errors and significantly improves images. Gray effects from dithering are not significantly effected when the pels are reduced and spread. When the image is graphic or otherwise more random than text scanned in the line and column direction, the correction may be deactivated.

摘要： A cartridge lockout system and method for an image forming apparatus, which includes a cartridge and a wheel rotatably mounted on the cartridge. The wheel has a plurality of digital indicators, each digital indicator being in a first condition or a second condition. A sensor is secured to the image forming apparatus adjacent the digital indicators for sensing the digital indicators and the first and second conditions of the digital indicators and producing a sensor signal during rotation of the wheel. Further included is an engine that has a machine class code and a cartridge support registry data table stored therein. The engine is in electrical communication with the sensor, receives the sensor signal, generates a cartridge class code based on the sensor signal, compares the cartridge class code to the machine class code, and disables operation of the engine if the cartridge class code does not match the machine class code in the cartridge support registry data table.

摘要： One aspect of the invention is directed to a toner cartridge including a sump for carrying a supply of toner. An agitator is rotatably mounted in the sump, and the agitator has a first end and a second end. An encoded wheel is coupled to the first end of the agitator. The encoded wheel is structured and adapted to include a first preselected cartridge characteristic indicia having a first extent, a stop indicia having a second extent larger than the first extent and a start indicia having a third extent larger than the second extent. Each indicia may be in the form of a slot. Preferably, the start indicia is positioned between about a 5:00 o'clock position and a 6:00 o'clock position. The stop indicia is positioned at about a 9:00 o'clock position. At least one preselected cartridge characteristic indicia is positioned between the start indicia and the stop indicia. At least one measurement indicia is located between about 200 degrees and about 230 degrees in a clockwise direction from the 6:00 o'clock position.
