Abstract: A printing apparatus includes a carriage, a carriage mover including a motor to move the carriage, a motor controller configured to control the motor, a power supply configured to selectively apply a first voltage or a second voltage to the motor controller, the second voltage being higher than the first voltage, and a transmitter to transmit a control signal for movement of the carriage when a predetermined control condition is satisfied. The first voltage is a voltage enabling the motor controller to move the carriage at a first speed by the motor. The second voltage is a voltage enabling the motor controller to move the carriage at a second speed by the motor, the second speed being higher than the first speed. The power supply applies the first voltage to the motor controller in a state where the transmitter transmits the control signal.

Abstract: A printer includes a carriage, a carriage moving mechanism including a motor, a motor driver that controls the motor, a stop instruction device, and an interlock device. The stop instruction device transmits a stop signal for the carriage or stops a driving permission signal for the carriage when a predetermined stop condition is satisfied. The interlock device is interposed between the motor and the motor driver and shuts off the motor from the motor driver after a lapse of a predetermined delay time of transmitting the stop signal or stopping the driving permission signal. The motor driver controls the motor to decelerate the carriage in at least a portion of a period before the delay time has elapsed.

Abstract: Job types include a first job type in which a second process is performed after a first process and a second job type in which the first process is performed and the second process is not performed. In a printer, a recording medium is allowed to be sandwiched by a center pinching roller and driving rollers. A controller of the printer includes a first primary elevation controller that controls the center pinching roller such that the center pinching roller stays down on the driving rollers to hold the recording medium in performing the first process in the first job type and a first secondary elevation controller that controls the center pinching roller to move upward and stay away from the driving rollers in performing the first process in the second job type.

Abstract: A printer includes a motor power supply line connecting a carriage motor with a power source, a sensor power supply line connecting a rotary encoder with the power source, a circuit breaker provided on the motor power supply line and interrupting electrical power if a cover sensor detects that a front cover is open and permit connection if the cover sensor detects that the front cover is closed, and a controller controlling the carriage motor and a recording head based on a position of a carriage detected by the rotary encoder.
