  • Patent number: 9919529
    Abstract: Provided is a cap unit that can prevent or suppress collision between the drive gear and intermittent gear when the drive gear and intermittent gear begin to mesh. A cap unit 25 has a moving mechanism 28 that moves a cap 26. The moving mechanism 28 has an intermittent cam gear 36 with a cam channel 43; a drive gear 35; and a cap holder 45. The cap holder 45 includes a holding member 48 that holds the cap 26; a cam follower pin 49; a pin support mechanism 50 that supports the cam follower pin 49; and a coil spring 51 that urges the cam follower pin 49 toward the bottom 43a of the cam channel 43. A slope 57 is disposed to the bottom 43a of the cam channel 43. The cam follower pin 49 is on the slope 57 when meshing of the intermittent cam gear 36 and drive gear 35 is disengaged, and the intermittent cam gear 36 turns in conjunction with the cam follower pin 49 moving on the slope 57 due to the urging force of the coil spring 51.

  • Patent number: 9895915
    Abstract: Example implementations relate to swath height error compensation. Some examples may determine a density of an image to be printed in an overlap area of a printing material. The overlap area may include target pixels capable of being printed by a first set of drop ejection elements and a second set of drop ejection elements that are redundant to the first set of drop ejection elements. Some implementations may also determine a mask to apply to the first and second set of drop ejection elements based on the determined density, and the mask may designate at least one additional drop to apply to at least one target pixel in the overlap area by at least one of the first and second set of drop ejection elements. Some implementations may also apply the mask to the first set of drop ejection elements and the second set of drop ejection elements.

  • Patent number: 9889677
    Abstract: An ion writing unit including an ion generator and an array of electrode nozzles aligned to receive and guide generated ions. The ion writing unit convertibly operates between at least a first mode and a second mode. In the first mode, ions flow from the ion generator through selected nozzles at a first flow rate to cause image formation on an electrically biased passive e-paper spaced apart from the electrode holes. In the second mode, ions flow from the ion generator through at least some electrode nozzles at a second flow rate that does not cause image formation on the electrically biased passive e-paper.

  • Patent number: 9862217
    Abstract: A printing apparatus that is capable of executing, based on printing data, printing onto a first side of a printing medium and printing onto a second side, which is the back side of the first side, after the printing onto the first side is provided. A print density of a predetermined region at a rear end of the printing medium in a transporting direction at a time of printing of the first side is identified based on the printing data. Conversion data, which is a conversion coefficient to make the identified print density equal to or lower than a predetermined density, is acquired. The printing data is converted by means of the conversion data. Printing onto the first side is executed based on the converted printing data.
