  • Publication number: 20170259591
    Abstract: A printing apparatus includes a print section to perform printing on a medium, a supply path to supply the medium to the print section, a correction roller pair to enable the medium transported on the supply path to strike the correction roller pair to correct skewing of the medium, an adjusting mechanism for adjusting a nip load applied to the correction roller pair, and a controller to control the adjusting mechanism based on print job information.

  • Publication number: 20170120632
    Abstract: A printing apparatus includes a printing unit that prints an image on a sheet by using ink, a feed path along which the sheet is transported toward the printing unit, a switchback mechanism that, when two sides of the sheet are to be printed, switches back the sheet of which one of the two sides has been printed and sends the sheet to the feed path, and a correction roller pair capable of correcting skew of the sheet by having firm contact with the sheet transported along the feed path.

  • Patent number: 9527293
    Abstract: A recording apparatus includes a recording head with liquid ejecting nozzles which eject a liquid onto a recording medium provided in a nozzle surface, a wiper which wipes the nozzle surface, and a cover which is positioned between the recording medium and a rim of the nozzle surface and covers the rim of the nozzle surface.

  • Patent number: 8870336
    Abstract: To detect an edge part of a medium with accuracy although the medium includes a false detection element, more than one change point, which changes from a condition that an output of an optical sensor indicates existence of a print medium to a condition that the output indicates non-existence of the print medium, is detected while the optical sensor moved on the print medium along a main scanning direction. A right edge part candidate detection process and a left edge part candidate process are performed to detect at points immediately before output changes as the right and left edge part candidates of the medium when the output of the optical sensor continuously indicates a condition of non-existence of the medium while the optical sensor and the print medium are moved further along the main scanning direction for a predetermined distance from the detected change points.

  • Patent number: 8528894
    Abstract: A transport device includes a set section, a sheet sensor, and a feeding member. When a detection member does not retract, the sheet sensor outputs an OFF-detection signal. The feeding member is displaced between a feed position and a non-feed position on the basis of the detection signal. At the feed position, the feeding member comes in contact with the sheet set in the set section from above and feeds the sheet toward the downstream side on a transport path. At the non-feed position, the feeding member is separated upward from the feed position. A method, which detects a sheet in the transport device, includes displacing the feeding member from the non-feed position to the feed position, and detecting that the sheet does not exist in the set section when an OFF-detection signal is output from the sheet sensor while the feeding member is positioned at the feed position.

  • Patent number: 8356810
    Abstract: A transport device includes a stopper which comes into contact with a target ahead of a guide surface of a guide member and regulates movement of the target and a slider which slides by contact of the target with the stopper. The stopper has a first regulation surface with which the target comes into contact ahead of the guide surface of the guide member, and a second regulation surface which regulates the movement of the target which moves along the first regulation surface. A damper mechanism is connected to the slider and has a damper force that weakens kinetic energy by the target that the stopper receives.

  • Patent number: 8292289
    Abstract: A transport device, which transports a sheet set in a set section toward the downstream side on a transport path, includes a restricting member. The restricting member is provided at a set position of the sheet in the set section, and is displaced to restrict the sheet moving toward the downstream side on the transport path. The restricting member includes a restricting section that comes in contact with a front end of the sheet from the downstream side on the transport path, and is rotatable about a shaft extending along the transport path so as to be displaced between a first position where the restricting section protrudes on the transport path and a second position where the restricting section retracts from the transport path.
