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.
Claims12
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;
- a recovery mechanism for performing recovery processing of the printing unit;
- a switching unit configured to switch a transmission destination of a driving force of the motor between the conveyance unit and the recovery mechanism;
- and
- a control unit configured to execute control,
- wherein the control unit is configured to stop the motor which is rotating at a target position, is configured to execute holding control to hold the motor at a stop position, and is configured to update, 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, and
- wherein the control unit is configured to execute the holding control in a case where the transmission destination of the driving force of the motor switched to by the switching unit is the conveyance unit and is configured not to execute the holding control in a case where the transmission destination is the recovery mechanism.
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, a motor configured to drive the conveyance unit, a recovery mechanism for performing recovery processing of the printing unit, and a switching unit configured to switch a transmission destination of a driving force of the motor between the conveyance unit and the recovery mechanism, the method comprising:
- stopping the motor which is rotating at a target position;
- executing holding control to hold the motor at a stop position;
- and
- updating, 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
- wherein the holding control is executed in a case where the transmission destination of the driving force of the motor switched to by the switching unit is the conveyance unit and is not executed in a case where the transmission destination is the recovery mechanism.
A conveyance apparatus comprising:
- a conveyance unit configured to convey a sheet;
- a motor configured to drive the conveyance unit;
- a switching unit configured to switch a transmission destination of a driving force of the motor between the conveyance unit and a mechanism different than the conveyance unit;
- and
- a control unit configured to execute control,
- wherein the control unit is configured to stop the motor which is rotating at a target position, is configured to execute holding control to hold the motor at a stop position, and is configured to update, 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, and
- wherein the control unit is configured to execute the holding control in a case where the transmission destination of the driving force of the motor switched to by the switching unit is the conveyance unit and is configured not to execute the holding control in a case where the transmission destination is the mechanism.
