摘要： A media sensor for an image forming apparatus is operative to sense and distinguish opaque, transparent or no media in a media path. In one embodiment, an optical source and detector are positioned on opposite sides of the media path, at an acute, non-zero angle with respect to a direction normal to the media path. In other embodiments, an optical source and detector are co-located on the same side of the media path with an optical barrier between them, and one or more reflective surfaces positioned on the opposite side. With no media in the media path, the detector receives a readily detectable amount of optical energy emitted by the source. For opaque media, the detector receives very little, if any, optical energy emitted by the source. For transparent media, the detector receives a level of optical energy between that in the cases of opaque media and no media.

摘要： A method and device for monitoring toner transfer within an image forming device is described herein. A reflectivity sensor senses movement of a toner transfer gear operatively connected to a toner transfer system. A threshold unit generates a dynamic threshold based on the output of the reflectivity sensor. In one embodiment, the threshold unit generates the dynamic threshold based on a time delayed average of the sensor output. An instantaneous sensor output is compared to the dynamic threshold. Based on the comparison, the device determines the how much the toner transfer gear has rotated, and therefore, how much toner has been transferred from the toner cartridge.

摘要： A method of aligning print images of an electrophotographic machine on a print medium includes providing a plurality of rotating photoconductive drums in the electrophotographic machine. Each of a plurality of laser beams is reflected off of a respective one of a plurality of reflectors. Each reflector rotates relative to the respective laser beam to thereby scan the laser beam across a respective one of the photoconductive drums to produce a scan line in a scan direction. The relative rotation between the laser beams and the respective reflectors is cyclically repeated to thereby produce a plurality of substantially parallel scan lines on each photoconductive drum. Each scan line is displaced from an adjacent scan line by a scan line separation distance in a process direction perpendicular to the scan direction. Toner is applied to each scan line on the photoconductive drums. A moving toner transfer medium contacts each photoconductive drum at a respective toner transfer nip. A first toner transfer nip is associated with a first reflector. A second toner transfer nip is associated with a second reflector. A length of the toner transfer medium between at least the first toner transfer nip and the second toner transfer nip is a non-integer multiple of the scan line separation distance. The length of the toner transfer medium has an integer portion and a fractional portion when expressed in units of the scan line separation distance. A speed of the rotation of the second reflector is temporarily increased or decreased dependent upon the fractional portion of the length. The toner is transferred from the photoconductive drums to the toner transfer medium. The toner is transferred from the toner transfer medium to the print medium. The machine controller provides raster image data to the respective laser printheads after accounting for the relative phase relationships between the respective reflectors. Raster scan data is synchronized in both scan and process directions to produce scans on the transfer medium that overlay those deposited at an earlier photoconductive drum.

摘要： An ASIC (5) has four driver circuits (19a-19d), each with different output power. One of those driver circuits is selected from the content of register (13) on the ASIC. The register content being decoded by a decoder (15) on the ASIC to a signal which activates a single one of the drivers. The register is loaded from an external microprocessor during each initialization of a printer (1) in which the ASIC is a component. The ASIC is designed with the range of the powers of the drivers bracketing the estimated needs of the load to be attached to the ASIC. This permits the ASIC to be completed only once, while the most suitable driver for the final load is determined subsequently and selected by the entry of data to activate that driver into the register with each initialization of the printer. The ASIC need not have nonvolatile memory and only a single set of ASIC masks and other design aspects need be completed.

摘要： A motion control system for controlling the motion of an intermediate transfer member in an image forming apparatus is provided in which a measuring member directly contacts the intermediate transfer member and generates signals proportional to the surface motion of the member. The measured surface motion is provided as a feedback signal to a motor controller, which compares the feedback signal with a reference signal. The difference between the signals is used to adjust the control of the drive motor for the intermediate transfer member drive roller in order to maintain a constant velocity for the intermediate transfer member.

摘要： An electrophotographic image forming apparatus transfers image information relating to an image to be formed on a medium, while maintaining desired low levels of electromagnetic emissions. The apparatus includes an image processor that generates low-frequency image information signals containing the image information. A low-frequency interface is connected to the image processor for transferring the low-frequency image information signals. A control circuit, connected to the low-frequency interface, receives the low-frequency image information signals generated by the image processor. The control circuit operates on the low-frequency image information signals to form a high-frequency image information signal therefrom, where the high-frequency image information signal contains the image information. The apparatus also includes a high-frequency interface connected to the printhead control circuit for transferring the high-frequency image information signal. An image formation device, connected to the high-frequency interface, forms an image on the medium. The image formation device forms the image based on the image information contained within the high-frequency image information signal.
