  • Publication number: 20170090379
    Abstract: A paper conveyance roller pair on the lower flow side of an auto cutter which cuts a target recording medium (long paper) at predetermined timing during a printing operation includes a powder brake mechanism which brakes the paper conveyance roller pair by changing the degree of agglomeration of magnetic powder with a magnetic force generated by a coil based on an excitation current value so as to continuously vary a transmission torque. When the target recording medium is cut, a control section varies an excitation current of the power brake mechanism to increase a load torque to be applied to the paper conveyance roller pair, and applies tension larger than usual to the target recording medium pinched by the paper conveyance roller pair.

  • Publication number: 20160216672
    Abstract: A printing device includes an image former performing an image formation on a recording medium in a rolled shape, and including a first roller pair that rotates to convey the recording medium in the rolled shape, and, a supplier including a second roller pair that rotates to convey the wound-off recording medium in the rolled shape to the image former, and a controller that actively rotates the second roller pair. The image former includes a determiner that determines whether or not the first roller pair that conveys the recording medium in the rolled shape conveyed from the second roller pair has held the recording medium in the rolled shape. When the determiner determines that the recording medium in the rolled shape has been held, the controller stops the active rotation of the second roller pair.
