Abstract
A print apparatus has a supporting section for supporting a roll of a continuous sheet, a driving mechanism having a motor for rotating the roll supported by the supporting section, a detection unit configured to detect a rotation state of the roll supported by the supporting section, a conveyance roller for conveying the continuous sheet drawn out from the roll and a print unit configured to form an image on the continuous sheet conveyed by the conveyance roller. A control unit is configured to obtain information indicating a moment of inertia of the roll supported by the supporting section based on detected values of the detection unit and to adjust a driving torque of the motor based on the obtained information, intermittently during printing.
