Abstract
A printing apparatus includes a printing unit, a conveyance unit, a motor, and a control unit. The printing unit performs printing on a sheet. The conveyance unit conveys the sheet to a printing position for the printing unit. The motor drives the conveyance unit. The control unit executes control. The control unit stops the motor which is rotating at a target position, executes holding control to hold the motor at a stop position, and updates, during execution of the holding control, the target position to a position different than the target position based on a rotational speed of the motor.
Claims13
A printing apparatus comprising:
- a printing unit configured to perform printing on a sheet;
- a conveyance unit configured to convey the sheet to a printing position for the printing unit;
- a motor configured to drive the conveyance unit;
- and
- a control unit configured to stop the motor in rotation at a target position, and configured to execute holding control to hold the motor at a stop position,
- wherein during execution of the holding control, the control unit is configured to:
- determine that the motor is stopped when a rotational speed of the motor has continued to be equal to or less than a first threshold for a predetermined period;
- and
- update the target position to a rotation position of the motor at which the motor is determined to be stopped.
A method for controlling a printing apparatus, wherein the printing apparatus includes a printing unit configured to perform printing on a sheet, a conveyance unit configured to convey the sheet to a printing position for the printing unit, and a motor configured to drive the conveyance unit, the method comprising:
- stopping the motor in rotation at a target position;
- and
- executing holding control to hold the motor at a stop position,
- wherein the executing holding control includes:
- determining that the motor is stopped when a rotational speed of the motor has continued to be equal to or less than a first threshold for a predetermined period;
- and
- updating the target position to a rotation position of the motor at which the motor is determined to be stopped.
A conveyance apparatus comprising:
- a conveyance unit configured to convey a sheet;
- a motor configured to drive the conveyance unit;
- and
- a control unit configured to stop the motor in rotation at a target position, and configured to execute holding control to hold the motor at a stop position,
- wherein during execution of the holding control, the control unit is configured to:
- determine that the motor is stopped when a rotational speed of the motor has continued to be equal to or less than a first threshold for a predetermined period;
- and
- update the target position to a rotation position of the motor at which the motor is determined to be stopped.
