摘要： A sensor detects the presence of opaque and transparent copy substrates in a substrate transporting path and includes an LED disposed near the transporting path for projecting light toward a reflector on the opposite side of the media transport path and a phototransistor located relative to the LED and reflector to receive light reflected from the reflector which is periodically interrupted by substrates within the transporting path to provide an output proportional to the light received from the LED via the reflector. The operating range of the phototransistor has a linear portion and a saturated portion. A control, electrically connected to the sensor, adjusts the phototransistor to maintain the output signal in the linear portion of the operating range. The sensor is tilted at an angle with respect to the horizontal of a copy substrate to be able to detect transparencies.

摘要： A maintenance system for an ink jet printer of the type having a full width array printhead has a movable carriage with a droplet sensor and a nozzle recovery device. As the carriage moves along the length of the printhead, each nozzle checked, one at a time, by the droplet sensor for the presence or absence of an ejected droplet and if the droplet has the correct directionality. Any problem nozzle is identified during a single traversal of the carriage across the printhead, and during a second traversal, the identified problem nozzles have a recovery operation performed on them such as being cleaned to remove any dried ink or other contaminating particles or being primed in the case of a clogged nozzle. The problem nozzles which have had a recovery operation performed on them and checked again by the droplet sensor is required for the entire array of nozzles, and ink is conserved since only predetermined nozzles are printed.

摘要： An infrared densitometer which measures the reflectivity of a selected region on a moving photoconductive belt covered at least partially with marking particles. Collimated light rays are projected onto the selected region of the moving photoconductive member with or without marking particles thereon. The light rays reflected from the selected region of the moving photoconductive member are collected and directed onto a photodiode array. A photodiode array generates electrical signals proportional to the diffuse component of the total reflectivity of the selected region of the photoconductive member with and without marking particles thereon. Circuitry determines a control signal as a function of the difference in electrical signals.

摘要： A flash exposure photocopier provides a mechanism for automatically controlling photoreceptor exposure levels to compensate for the effects of documents having backgrounds of different densities. A photosensor and lens assembly is located within a flash housing in a position whereby a large portion of the document is imaged by the lens onto the surface of a chip having a plurality of individual photosensors contained thereon. The outputs of each photosensor are integrated and applied to a comparator set at a particular reference level. The comparator output controls the duration of the flash source so as to quench lamp operation when an input level is reached corresponding to the particular reference level set. The integrated photosensor outputs are also summed and a signal representing their average value is compared to the signal which triggers the comparator. The ratio of these signals is used to identify documents with high area coverage and hence high toner usage. The toner dispensing rate is then regulated accordingly.
摘要翻译：闪光曝光复印机提供了一种自动控制感光体曝光水平的机制，以补偿具有不同密度背景的文档的影响。光电传感器和透镜组件位于闪光灯壳体内的位置，由此将大部分原稿通过透镜成像到具有多个单独光电传感器的芯片的表面上。每个光电传感器的输出被积分并应用于在特定参考电平上设置的比较器。比较器输出控制闪光源的持续时间，以便在达到与特定参考电平设置对应的输入电平时熄灭灯泡操作。积分的光电传感器输出也相加，并将表示其平均值的信号与触发比较器的信号进行比较。这些信号的比例用于识别具有高面积覆盖率的文档，因此识别高碳粉用量。然后相应地调节调色剂分配速率。

摘要： The present invention is concerned with a self-adjusting document sensor compensating for degradation of the sensor system. A suitable light source and a detector are provided, the output of the detector being fed into an amplifier whose gain depends upon a feedback signal. Periodically, the output of the amplifier is compared to a reference. If the output of the amplifier falls below the reference, a pulse is sent to a ripple counter whose digital output is fed back to the amplifier to change the gain of the amplifier. If the detector is an unbiased photodiode operating in the transconductance mode, the leakage currents and their subsequent effect on output with amplifier gain changes will be minimized.

摘要： An integral, compact infrared reflectance densitometer including a substrate supporting an LED, a control photodiode to compensate for component degradation, a background photodiode to compensate for background radiation, and a large area photodiode to provide an electrical signal representative of the amount of toner particles on the photosensitive surface. Also carried on the substrate is a field lens to focus light rays reflected from the photosensitive surface onto the signal photodiode. The substrate is precisely secured to a molded housing having integral collector and collimating lenses. Four extending pins on the housing engage four apertures on the substrate to locate the substrate with respect to the housing and align the LED and field lens carried on the substrate with the collector and collimating lenses of the housing. Also carried on the substrate is an aperture box to permit a portion of the LED light to project through the collimating lens to the photosensitive surface and a portion of the light to be reflected onto the control photodiode to control light output. The light rays reflected from the photosensitive surface are gathered in a collector lens and projected through the field lens to be focused onto the signal photodiode. An L-shaped clip and an appendage with an elongated aperture extend from opposite ends of the housing to position and align the infrared reflectance densitometer in the reproduction machine with respect to the photosensitive surface.

摘要： A corona generating device having a corona electrode supported between a pair of endblock assemblies, each endblock assembly defining a space for the passage of the electrode, and non-conductive inserts seated in the spaces in the endblock assemblies and surrounding the electrode. The non-conductive inserts are made of a material with high dielectric strength and resistent to corrosive atmosphere. The inserts can be easily and inexpensively replaced and they protect the endblock assemblies from effects of applying high voltages to the corona electrode.

摘要： A corona generating device including a coronode in the form of a wire supported between insulating end block assemblies. Each assembly is constructed of mating half-sections which jointly define a substantially closed and insulated cavity lined with a conductive insert. The insert on the high voltage side of the coronode serves to couple electrically the high voltage terminal to the coronode via a first conductive bead carried by the coronode. The coronode is held taut by means of a loaded compression spring carried within the insert on the half-section removed from the high voltage supply, the spring bearing against the conductive insert on one end and against a second conductive bean carried by the other end of the coronode.

摘要： To determine the spectra of objects that have different degrees of fluorescence, a plurality of reference databases are provided, each reference database being suited to a different degree of fluorescence. A most appropriate one of the reference databases is selected based on a predicted degree of fluorescence of an object for which a reflectance spectrum is to be determined. The prediction of the degree of fluorescence may be based on user input, or may be predicted by using a priori information, such as a priori knowledge of media types.
