  • Patent number: 10967633
    Abstract: In a printer configured to perform two-sided recording, a control unit generates a first correspondence relationship that associates a reference pattern with raster data of a first image in a medium transport direction, and a second correspondence relationship that associates the reference pattern with raster data of a second image in the medium transport direction, and, when the second image is recorded on a second surface, performs determination processing for determining whether the reference pattern detected by a detection unit and the raster data of the second image, which a recording unit records when the reference pattern is detected, match the second correspondence relationship.

  • Patent number: 10960693
    Abstract: After an ejector passes an ejection end position, a controller controls a second conveyor to convey a sheet in a sub-scanning direction. The ejection end position is a position at which ink ejection by the ejector ends before reaching a turn position. An ejection start position is a position at which ink ejection by the ejector starts after turning at the turn position. Based on positional relationship between the ejection end position and a standard position, the controller adjusts timing of conveyance of the sheet or shift the turn position from the standard position in a direction of reducing an overlap between a sheet conveyance period after the ejector passes the ejection end position and an ejector deceleration period before the ejector reaches the turn position. The standard position is a standard turn position of the ejector and is determined from the ejection end position and the ejection start position.

  • Patent number: 10752034
    Abstract: In a method for detecting an ejection abnormality of a nozzle according to the present disclosure, a plurality of nozzles of a liquid ejection head are caused to execute an operation of ejecting liquids so that a nozzle check pattern including check areas each drawn solely by each of the plurality of nozzles and a solid pattern including a solid printed area are formed on part of a sheet. A first density value indicating a density value of a ground color of the sheet and a second density value indicating a density value of the solid pattern are acquired. A threshold value for detecting an ejection abnormality of each of the plurality of nozzles is derived from the first density value and the second density value. It is determined, using the threshold value, whether or not each of the check areas of the nozzle check pattern is drawn.

  • Patent number: 10717305
    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.

  • Patent number: 10688808
    Abstract: A system and method for treatment of thread includes a thread printer that applies colored coatings to thread. A camera is positioned to capture images of the treated thread after it passes through an outlet of the thread printer. The system processes the images to determine whether the location of a selected segment of the treated thread corresponds to an expected location. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of one or more segment to automatically account for the misalignment.
