  • Publication number: 20110211030
    Abstract: An apparatus for performing duplex printing having a sheet feeding unit, a printing unit, a cutter unit, a drying unit, and a reverse unit. In the duplex printing, the printing unit prints a plurality of images on a first surface of a sheet fed from the sheet feeding unit. The sheet is a continuous sheet. The sheet printed on the first surface passes through the drying unit and is led to the reverse unit. The reverse unit feeds the reversed sheet to the printing unit and the printing unit prints a plurality of images on a second surface that is a back of the first surface of the sheet fed from the reverse unit. The cutter unit cuts the sheet printed on the second surface into a plurality of cut sheets each having the image printed thereon. The cut sheets pass through the drying unit and are ejected.

  • Publication number: 20110012972
    Abstract: An apparatus includes a guide unit configured to guide surfaces of a sheet, which is conveyed after passing through a recording unit, with respect to a vertical direction, the guide unit having an interval variable in the vertical direction, and a correction mechanism for correcting skew of the sheet, which is inserted into the guide unit, by pushing the sheet from both sides thereof in a sheet width direction. The interval of the guide unit in the vertical direction widens when the sheet is cut compared with that when correction is executed by the correction mechanism, and when the sheet is cut, conveyance of the sheet is temporarily stopped in a position of the cutter. In cutting, a loop of the sheet is formed on the guide unit the interval of which in the vertical direction has widened.
