  • Patent number: 11958306
    Abstract: In an example of the disclosure, a priming lane and a non-priming lane are identified within an image frame to be printed by a printer. A line of molten wax is applied to the roller. The molten wax when cooled is to form a wax ridge upon the roller. The roller having the formed wax ridge is wetted with the primer. The wetted roller is rotated against the substrate to apply the primer. A first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate. A second width of the roller that includes the wax ridge causes the primer to not transfer and thereby forms the non-priming lane upon the substrate.

  • Patent number: 11919300
    Abstract: An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

  • Patent number: 11912037
    Abstract: An ink is circulated in a circulation path including a supply sub-tank, a discharge head and a collection sub-tank in a head unit. If the amount of the ink in the head unit decreases, the ink stored in the buffer tank is replenished to the head unit. On the other hand, in a first non-replenishment time during which the ink is not replenished, the ink is circulated through the buffer tank, the collection sub-tank and the supply sub-tank in this order. Thus, a temperature fluctuation of the replenishment ink stored in the buffer tank is suppressed. As a result, even if the ink is replenished to the head unit from the buffer tank, physical properties, particularly a viscosity, of the ink do not largely vary.

  • Patent number: 11912045
    Abstract: A method of operating a printer evaluates the effect of printing a print job with two different orientations of the image content data for the print job. The orientation that produces the least increase in the cross-process direction displacement error for the inkjets in the printer is selected for printing the print job. By attenuating the increase in cross-process direction displacement error, the interval between printhead maintenance operations is increased.
