摘要： A method and system for controlling an image printing system in the presence of reload defects are provided. The method comprises placing toner images on an image bearing surface moving in a process direction, determining the density of the toner image or a portion thereof being printed on the image bearing surface, and printing a scheduled control patch at a location in the cross-process direction on the image bearing surface, wherein the location where each control patch is printed is dynamically changed based on the density of the toner image adjacent the control patch or a portion thereof.

摘要： A printing device includes at least one printing engine that has many sensors (first sensors and second sensors) and at least one engine controller operatively connected to the printing engine. The engine controller uses software to control operations of the printing engine. Also, at least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. At least one adapter card is operatively connected to the non-volatile memory and to the first sensors and second sensors. The first sensors correspond to the design of the controller and are items designed as original equipment of the printing device. To the contrary, the second sensors correspond to the design of the adapter card and are items designed to be installed in the printing device after the printing device is in post production, customer service. The adapter card receives feedback from the first sensors and the second sensors and the adapter card reads and modifies incoming print jobs before the print jobs are delivered to the controller.

摘要： A printing device has a printing engine that is at least partially made up of a customer replaceable unit or units. An engine controller is operatively connected to the printing engine. The engine controller uses software to control the operations of the printing engine. A non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. An adapter card is operatively connected to the non-volatile memory and to the customer replaceable units. The customer replaceable unit has a memory unit and the adapter card reads data from the memory unit. The adapter card uses the data to directly alter values within the non-volatile memory by bypassing the engine controller when communicating with the non-volatile memory. Further, the adapter card alters the non-volatile memory without altering the software used by the engine controller.

摘要： A method creates a printing image charge on a photoreceptor printing region of a photoreceptor within a printing apparatus and, simultaneously with the creating of the printing image charge, charges source patches on the photoreceptor outside the photoreceptor printing region. The method then transfers developer material from a donor roll to the photoreceptor. The source patches cause developer material to be removed from areas of the donor roll outside a donor roll printing region to create developer material-depleted regions. The method then reloads the donor roll with developer material using a magnetic brush and evaluates a reload function of the donor roll by characteristics of developer material on target patches with developer material in areas of the non-printing region of the photoreceptor adjacent the target patches. The method then alters the printing image charge to maintain the reload function within a predetermined range.

摘要： A control system for use with a development process including at least one magnetic roll with a settable speed is provided. The controller is directly or indirectly responsive to a reload feedback signal, which signal is generated in response to changes in output reload performance of the development process. In the case of direct responsiveness, the controller uses one or more reload feedback signals to facilitate magnetic roll speed setting. In the case of indirect responsiveness, the controller uses a reload sensitivity signal, which reload sensitivity signal varies as a function of input digital image content and output reload performance feedback, to facilitate magnetic roll speed setting.

摘要： Systems and methods of marking control achieve improved image quality in a multipass marking process by taking into account positioning errors that have already occurred in prior marking passes while building the image, and compensates for them in real-time by modifying the remaining interlace locations of the marking subsystem in order to minimize predicted image quality defect perception in the resultant image. The adjustment are preferably based on minimizing a defect perceivability metric. One such suitable metric is a frequency metric, preferably the power spectral density of the resultant image evaluated at the fundamental frequency (1/D), where D represents the spacing of marking devices, such as the spacing of print head nozzles.

摘要： Spectrophotometer color measurement with a target illumination system and a reflected illumination sensing system where the target surface is variably spaced from said spectrophotometer. Color correction calibration information corresponding to color measurements for known different spacings of a test target surface from the spectrophotometer are obtained and stored. In use, the spacing of the actual target surface from the spectrophotometer is measured to provide a target spacing information signal. That signal is automatically combined with the stored color correction calibration information for the corresponding distances to provide at least partial correction of color measurement errors of the spectrophotometer for variable spacing of the target surface relative to the spectrophotometer even with low cost fixed focus optics. The spectrophotometer output can be so corrected by changing the target illumination, such as by LED pulse width changes, and/or by corrective adjustment of the measured reflectances.

摘要： Systems and method provide compensation for temperature induced peak wavelength shift of LEDs is color parameter measuring systems that use a model to reconstruct target color parameter values from the reflectance values measured when the target is illuminated by LEDs. Several models may be constructed, with each model being trained at a unique temperature, resulting in a set of models that span the temperature range of interest. In real-time, the LED based color parameter measuring system measures the temperature and interpolates between the models to estimate the appropriate model to use at the temperature of interest. The estimated model is then used to perform the color parameter value estimation.
