    Abstract: A media sheet drive has a continuous belt of a dielectric material for transporting sheet media supported on the belt in a transport direction. A launch mechanism is used to launch a sheet medium onto a top surface of the belt. A charging circuit including a charging roller is used to charge a top surface of the sheet medium and the belt as the sheet medium is launched. Charging acts to generate an electrostatic tacking force to tack the sheet medium to the belt. The charging roller has a second function to smooth out curled edges of paper as it is acted on by the charging circuit so that the full extent of a launched sheet medium may be subject to the electrostatic tacking force.

  • Patent number: 10414158
    Abstract: In ejecting ink from unused ink ejection ports or ink ejection ports not used frequently onto a can body to suppress ink clogging, the ink clogging is suppressed while degradation in the quality of an image to be formed on the can body is suppressed. On the surface of a can main body 110, a main image MG, which is a main image, and a strip-shaped image OG, which is a sub-image, are formed. The strip-shaped image OG is formed using ink ejection ports not used at forming the main image MG or low-frequency ink ejection ports not ejecting ink frequently. Thus, ink clogging hardly occurs in an ink jet head.

  • Patent number: 9878542
    Abstract: A print device includes a processor, and a memory. The processor performs processes. The processes include a covering control processing controlling the cap into a covering state in which the cap covers the nozzle. The processes include supply processing supplying, after the covering control processing, the cleaning liquid to the cap from the supply flow path. The processes include hold processing holding, after the supply processing and in a state in which the cleaning liquid has soaked the nozzle face, the cleaning liquid in the cap. The processes include first determination processing determining, after the hold processing, whether a print request has been received. The processes include discharge processing discharging, in a case where a power on signal has been detected or in a case where the first determination processing has determined that the print request has been received, the cleaning liquid that has been held in the cap.

  • Patent number: 9827763
    Abstract: A liquid ejecting head includes an ejection surface which extends in a first direction (X-direction) and on which a plurality of nozzles ejecting a liquid are distributed; and protrusion sections that are formed on the ejection surface and protrude on a liquid ejection side in which the liquid is ejected. The ejection surface has abutting regions on which a sealing body that seals the plurality of nozzles by surrounding the plurality of nozzles abuts. When projecting the abutting regions and the protrusion sections along a first direction (X-direction) on a virtual line along a second direction (Y-direction) intersecting the first direction, the protrusion sections are disposed on the ejection surface such that projection of the protrusion sections crosses a boundary of projection of the abutting regions.
