Abstract
A printer takes up slack in media while suppressing excessive rewinding, and can check the movement of a movable member that moves following change in tension on the media. The printer drives the supply motor in a first operating mode in a slack removal operation that rewinds the recording paper (media) onto a paper roll 2, and stops driving the supply motor when the tension lever (movable member) moves from a slack-side first position toward a second position. In the movement checking operation, the supply motor is driven in a second operating mode with greater output than the first operating mode, rewinds the recording paper on the paper roll, and sets the tension lever to the second position.

A media conveyance device configured to convey a media delivered from a paper roll through a conveyance path comprising:
- a drive motor configured to rotate the paper roll;
- a pinch roller configured to be in contact with the media;
- a movable member configured to move between a first position and second position different from the first position based on a tension on the media, and disposed on the conveyance path between the paper roll and the pinch roller;
- a position detector configured to detect a current position of the movable member;
- and
- a control unit, wherein
- the control unit drives the drive motor in a first operating mode and rewinds the media onto the paper roll until the movable member moves from the first position to a specific position toward the second position, and
- the control unit drives the drive motor in a second operating mode with greater output than in the first operating mode, rewinds the media onto the paper roll based on the current position of the media member, and moves the movable member from the specific position to the second position.
A printer configured to print a media delivered from a paper roll through a conveyance path comprising:
- a printhead;
- a drive motor configured to rotate the paper roll;
- a pinch roller configured to be in contact with the media;
- a movable member configured to move between a first position and second position different from the first position based on a tension on the media, and disposed on the conveyance path between the paper roll and the pinch roller;
- a position detector configured to detect a current position of the movable member;
- and
- a control unit, wherein
- the control unit drives the drive motor in a first operating mode and rewinds the media onto the paper roll until the movable member moves from the first position to a specific position toward the second position, and
- the control unit drives the drive motor in a second operating mode with greater output than in the first operating mode, rewinds the media onto the paper roll based on a current position of the media, and moves the movable member from the specific position to the second position.
A control method of a printer configured to print a media delivered from a paper roll through a conveyance path including a printhead, a pinch roller configured to be in contact with the media, a drive motor configured to rotate the paper roll, and a movable member configured to move between a first position and second position different from the first position based on a tension on the media, and disposed to the conveyance path between the paper roll and the pinch roller, comprising;
- driving the drive motor in a first operating mode and rewinds the media onto the paper roll until the movable member moves from the first position to a specific position toward the second position, and
- driving the drive motor in a second operating mode with greater output than in the first operating mode, rewinds the media onto the paper roll based on a current position of the media, and moves the movable member from the specific position to the second position.
