摘要:
There is provided a printing method using a first motor that applies a driving force for rotating a roll body around which a printing medium is wound, a second motor that applies a driving force for intermittently driving a transport driving roller that transports the printing medium, and a print head that intermittently ejects ink onto the printing medium alternately with the driving of the second motor. The printing method includes driving the first motor such that tension applied to the printing medium is constant during at least a part of a period in which the second motor is driven and stopping the driving of the first motor during at least a part of a period in which the driving of the second motor is stopped.

A liquid ejecting apparatus includes a record head having nozzles that discharge liquid; a transporting path along which a medium is transported; a transporting mechanism that transports the medium along the transporting path; a sensor including a light-emitting element and a light-receiving element and disposed at a first position on the transporting path, the first position being located upstream relative to the record head in a transporting direction of the medium, the sensor outputting a signal in accordance with presence or absence of the medium at the first position; and a control unit that controls supply of power to the sensor and detects the presence or absence of the medium through the sensor. The control unit stops the supply of power to the sensor when the control unit detects a downstream end of the medium in the transporting direction, and resumes the supply of power to the sensor when the control unit detects an upstream end of the medium in the transporting direction.

A printer includes a motor, a position calculation unit, a speed calculation unit, a position control unit, a speed control unit, and a switching unit. The motor generates a driving force by which a transported object is transported. The position calculation unit calculates a current position of the transported object through driving the motor. The speed calculation unit calculates a current speed of the transported object through driving the motor. The position control unit controls the motor using at least PI control on the basis of the current position calculated by the position calculation unit and a target position. The speed control unit controls the motor using at least PI control on the basis of the current speed calculated by the speed calculation unit and a target speed. The switching unit switches from control of the motor using the speed control unit to control of the motor using the position control unit at a position that is a predetermined distance before a target stop position to which the motor is driven.

A printing device includes: a driving motor that applies a power rotating a roll body in which a medium is rolled; a driving roller that transfers the power of the driving motor to the roll body; a transport motor that applies a power transporting the medium; a transport roller that is provided further to the downstream side than the roll body in the transport direction of the medium; and a looseness acquiring unit that acquires an looseness between the driving roller and the transport roller. When the looseness is equal to or more than a predetermined looseness, the driving motor is controlled on the basis of the looseness acquired by the looseness acquiring unit. When the looseness is less than the predetermined looseness, the driving motor is controlled on the basis of tension between the driving roller and the transport roller.
