  • Publication number: 20190302673
    Abstract: A printing apparatus for printing an image on paper includes first and second units, and a registration unit. The first unit detects a first length, along a predetermined conveyance direction, of paper conveyed from a feed port. The second unit detects a second length, along a direction intersecting with the predetermined conveyance direction, of the paper set in the feed port. The registration unit registers a size corresponding to the first and the second lengths of the paper set in the feed port, based on second unit detection. The first unit detects the first length of first paper conveyed to print a predetermined test pattern before second paper is set in the feed port. The registration unit registers a regular size based on a result of first unit detection on the first paper from among regular sizes corresponding to a result of second unit detection on the second paper.

  • Patent number: 9428357
    Abstract: A conveying device and a conveying control method that can control a phase of a main conveying roller and a position of a print medium with an inexpensive configuration and a fast throughput are provided. For that purpose, an LF roller phase is obtained, phase matching control is performed so that the print medium comes to a desired position when the LF roller is at a desired phase, and skewing of the print medium is corrected by the same control method as the phase matching control.

  • Patent number: 9004488
    Abstract: A conveying apparatus includes a first pair of rollers having a drive roller and a pinch roller driven by the drive roller, a second pair of rollers provided downstream of the first pair of rollers, and an arm member supporting the drive roller and adapted to be swingable such that a force for pressing the drive roller against the pinch roller increases as a conveyance resistance of the sheet increases. The force for pressing the drive roller against the pinch roller decreases if driven by the moving sheet. The conveying speed of the second pair of rollers is set to be higher than the conveying speed of the drive roller so as to cause the drive roller to be driven by the sheet in the case where a skew of the sheet has been corrected and the sheet having the skew corrected is conveyed by the second pair of rollers.

  • Patent number: 8366253
    Abstract: A printer includes a set cover pivotally movably provided on a carriage. The cover can be set in a closed state in which the cover presses a head of the cartridge housed in the housing portion and an open state in which the cover opens the housing portion when the cartridge is replaced. A release lever is subjected to a bias force so as to protrude from an inner wall surface of the housing portion. The release lever is movable against the bias force. The release lever comes into contact with an end of the cartridge which faces the bottom surface when the cartridge is inserted into the housing portion. The release lever contacts the rear surface of the cartridge housed in the housing portion. The bias force is stronger when the cover is in the open state than when the cover is in the closed state.

  • Patent number: 8091976
    Abstract: There are provided an inkjet printing apparatus and a method of predicting which can perform an accurate ink remaining amount detection. An inkjet printing apparatus is for performing printing onto a print medium by using a print head including an energy generating element generating energy used for ejecting ink from an ejection opening. The apparatus has a print head temperature detecting unit, an atmosphere temperature detecting unit and a predicting unit. The predicting unit drives the energy generating element at the time a difference between the temperature of the print head before driving the energy generating element and the atmosphere temperature detected by the atmosphere temperature detecting unit is less than a predetermined temperature.

  • Patent number: 7641184
    Abstract: In the image reading and recording apparatus, a separating and feeding unit, a paper end detecting unit, a reading unit, a conveying unit, and a recording unit are arranged in this order from the upstream of the conveying direction. The separating and feeding unit has a switching unit for selectively switching between a separating function of separating the uppermost one of stacked sheets and a feeding function of feeding each separated sheet at a predetermined speed. After a sheet is separated, switching from the separating function to the feeding function is carried out before the paper end detecting unit detects the top end of the sheet.
