  • Patent number: 11104165
    Abstract: Previously, a customer may not have known which information was acquired and may have felt anxiety. In addition, only internal data of the apparatus was previously acquired. However, in order to determine a trouble in the inkjet printer with high precision, visual information such as a state of a printer mechanism or a conveyance line and a print result is also necessary to determine the apparatus state. Therefore, it is necessary to establish a maintenance system capable of acquiring such information.

  • Patent number: 11104162
    Abstract: Methods, Apparatus, Devices and Systems herein load a firing distance into a distance counter of a printing device. The firing distance is the distance from the current position of a printhead of the printing device to a marking location on a substrate and the distance is calculated based on an angular encoder operatively associated with a roller used to transport a marking media to the printhead for marking. These devices and methods count the firing distance in angular distance increments as a function of the encoder angular position to correct for encoder roller runout using the distance counter, based on relative movement of the substrate and printhead. When the distance counter reaches the last discrete distance increment corrected for encoder roller runout of the firing distance, these devices and methods load the fractional remaining distance of the firing distance into a time counter of the printing device.
