  • Patent number: 9375955
    Abstract: A printing apparatus includes a printing unit, a first and second conveying units conveying a printing medium, a driving unit driving the conveying units and a control unit controlling the driving unit. A load mutually acting on the conveying units through the medium in a conveyance state by the conveying units is recursively calculated for each predetermined conveyance unit while setting the initial value to 0. The driving unit is controlled based on the calculation result at the time of the transition to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state of the medium from the conveyance state by the conveying units to a conveyance state only by the second conveying unit.

  • Patent number: 9327527
    Abstract: A printing apparatus includes a printing unit, first and second conveying units conveying a printing medium, a driving unit driving the first and second conveying units, and a control unit controlling the driving unit. The conveyance state of the printing medium makes transition from a first conveyance state in which the printing medium is conveyed only by the first conveying unit to a second conveyance state in which the printing medium is conveyed by both the first and second conveying units. The control unit controls the driving unit based on a fluctuation in a load that mutually acts between the first and second conveying units through the printing medium to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state from the first conveyance state to the second conveyance state.
