摘要： An image reproduction device for document processing has a nominal processing speed at which it can process sheets continuously at a nominal document quality. However, the image reproduction device is arranged to process sheets at a continuously variable processing speed including the nominal processing speed. The actual processing speed is selected in dependence on operational conditions. In particular, the device is arranged to gradually adjust the processing speed from one processing speed to another processing speed. A control structure is given to select the variable processing speed in dependence on operational conditions, and to operate the image reproduction device at the selected processing speed. In a particular application of the variable speed, a print job may be started at an increased processing speed and then gradually fall back to the nominal speed, giving a fast start and a shorter processing time for short print jobs.

摘要： An image reproduction device includes a print processing system and a print sheet conveying system that conveys sheets with a continuously variable and dynamically adjustable processing speed. The device lowers the processing speed when the mains connection cannot deliver sufficient power to run at a nominal processing speed and is provided with a current monitor unit for monitoring total electrical current drawn by the device from the mains connection and a control unit connected to the current monitor unit and arranged for dynamically adjusting the processing speed to a lower value when the total electrical current is above a preset maximum value. The control unit regulates the lower processing speed value to make sure that the total electrical current drawn by the device from the mains connection is kept substantially equal to the preset maximum current value until the mains power is again sufficient for running at nominal processing speed.

摘要： A method of and apparatus for printing color images by the superimposition of a number of separations, using a first half-tone technique optimized for surface reproduction, such as dithering, and a second half-tone technique, differing from the first and optimized for edge reproduction, such as thresholding with error diffusion, is disclosed. The second half-tone technique is used in edge transitions for pixels of a separation which substantially influences the edge transition, and the first half-tone technique is used outside the edge transition. And the first half-tone technique is used throughout in the case of pixels of a separation which provide no or minimal contribution to the edge transition.

The image printing apparatus also includes at least one image forming unit provided with electronic image line correction devices for feeding image line correction signals to the electrode track activating devices in order to shift in time for each electrode track a printing period in which a printing voltage is applied to the electrode track in accordance with an image information signal.
