    Abstract: A method for correcting cross-track position errors in a digital printing system having a linear printhead includes printing a test target including a plurality of alignment marks. A data processing system is used to automatically analyze a captured image of the printed test target to determine a measured position for each of the alignment marks. The measured positions for the alignment marks is compared to reference positions to determine measured cross-track position errors. A cross-track position correction function is determined responsive to the measured position errors, wherein the cross-track position correction function specifies cross-track position corrections to be applied as a function of cross-track position. A corrected digital image is determined by resampling the image lines of a digital image responsive to the cross-track position correction function.

  • Patent number: 10029490
    Abstract: Paper has a detection pattern having a length in a main scanning direction, the length becoming shorter from upstream to downstream along a paper feeding direction. An image sensor detects the detection pattern and outputs a detection signal including data in the main scanning direction (length y). A control unit calculates a position of a vertex of the detection pattern, by using the detection signal, a feeding speed, an angle being half of the vertex angle of the pattern, and an imaging time, so as to correct an image forming position on the back side to coincide with an image on the front side. The detection signal from the sensor with a low operation speed is processed according to a method utilizing a shape feature and the like of the detection pattern, thereby precisely detecting the position of the paper in the feeding direction.

  • Patent number: 10003714
    Abstract: An image forming apparatus includes an acquiring unit configured to acquire atmosphere pressure in the installation place of the image forming apparatus, photoconductors, light sources configured to radiate laser light, and a polygon mirror configured to be rotatable. The polygon mirror exposes the photoconductors by reflecting the laser light toward the photoconductors while rotating. The image forming apparatus further includes a control device configured to control rotation of the polygon mirror. The control device outputs an enable signal for allowing the image forming apparatus to perform printing, if rotation of the polygon mirror is stabilized after start of the rotation, and advances the timing of outputting the enable signal as the atmosphere pressure increases.

    Abstract: A system and method for adding a print medium digitally to a print system are disclosed. The print system has a control unit for controlling a print job queue and print system parameters, a print engine, an input section, and a receiving section. The method includes receiving the print medium in the input section, loading a test job having prescribed print system parameters in the receiving section, printing a large number of prints of the test job to establish an unwanted deposit of marking material on the side of the stack, and establishing whether or not an unwanted marking material is deposited on a stack height side of the stack. If unwanted deposit is established, then printing a number of blank sheets of the same print medium, adjusting the print system parameters, and returning to printing. If no unwanted deposit is established, approving the use of the print medium.
