摘要： A color image forming apparatus includes a first density detecting unit for detecting a density of a first detection toner image formed on an image bearing member or a transferring material carrying member, and a second density detecting unit for detecting a density of a second detection toner image fixed onto a transferring material, and executes image density control based on a detection result of the first density detecting unit and a detection result of the second density detecting unit. A detecting light application position of the first density detecting unit and a detection light application position of the second density detecting unit are almost equal relative to a perpendicular direction to a transferring material conveying direction. It is thereby possible to shorten time required for density control and to prevent deterioration of density control accuracy caused by a temporal change and a positional change in the density of a detection toner patch.

摘要： During the operation of a document processing system machine and job data are collected from a document processing system. Optionally, machine information, both for the specific machine and population based data are acquired from a database or server. Having accumulated the job data and machine data, the diagnostic inference engine performs an analysis to determine the initial diagnosis of the document processing system. After obtaining the initial diagnosis, the system determines the test patterns to be printed and the image quality tests to be performed. The system then prints test patterns, and scans the patterns to determine image quality parameters and/or to automatically identify image defects. Optionally, image defect information may also be provided by the customer or the service engineer via a user interface. Next, a diagnostic inference engine uses the results of the image quality analysis to refine the initial diagnosis. Then, the diagnostic results are output, stored, and optionally displayed to, for example a customer or a customer service engineer. Based on the diagnostic results, and if problems are found, the machine enters a repair sequence. In particular, the machine can request either a customer or a customer service engineer repair action, or, alternatively, enter an auto-correction or an auto-calibration mode to repair itself. Upon completion of one or more, or any combination, of these repair actions, the machine verifies its operation and again checks to ensure the repairs have been completed successfully.

摘要： An improved and lower cost color spectrophotometer, especially suitable for on-line color printer color control systems, incorporating a low cost commercial imaging chip, which normally only forms part of a three row, three color, document imaging bar used for imaging documents in scanners, digital copiers, or multifunction products, having multiple photo-sites with at least three different color filters in three rows. This multiple photo-sites chip may be modified to also provide unfiltered photo-sites. This spectrophotometer may have a substantially reduced number of different LED or other spectral illumination sources, one of which may be for white light, yet provide multiple spectral data outputs from the differently filtered photo-sites being simultaneous illuminated by the light reflected from a color test target area which is being sequentially illuminated by the respective limited number of LEDs, enabling broad spectrum information and color control.

摘要： High precision image density characteristics are stable maintained over extended periods of time. For this purpose, a first calibration operation is preformed in which a predetermined grayscale pattern is formed on a recording paper and this pattern is read by a reading device to produce a LUT for controlling the laser output in accordance with the image signal (gamma correction). A second calibration operation is performed after the first calibration operation wherein a patch is formed on an image carrier by the laser output controlled by the above LUT, its density is detected by a detector and a correction LUT is generated in accordance with the detected density.

摘要： An unfixed toner image of a reference pattern is formed on a photosensitive member, the unfixed toner image is measured by a development density sensor 13, and the amount of toner to be supplied to a developing device 4 is controlled by a toner supply control unit 60 on the basis of a measurement output, thereby maintaining the image quality constant. If it is judged from a result of a detection of a state amount such as the temperature and the humidity by a state amount sensor 19 that there is a fear that the image quality exceeds an allowable range, a fixed image of a reference pattern is formed on a record medium such as a banner sheet, and the fixed image is measured by an optical sensor 10. Operation amounts such as the charge amount and the exposure value of an image output unit 100 are controlled by an image density control unit 20, thereby maintaining the image quality to be within the allowable range.
