An image forming apparatus includes a communication interface, an image forming unit, a plurality of sheet feeders, and a motor configured to selectively apply a drive force any of the sheet feeders. A transmission assembly switches transmission to any one of the sheet feeders. A controller receives preceding data from the communication interface, and, in response, controls the transmission assembly to initiate a switch of the transmission of the drive force to a standard sheet feeder among the plurality of the sheet feeders. In response to receipt control data received after the preceding data, the controller controls the image forming unit, motor, and transmission assembly to form an image on the sheet based on an image forming condition included in the control data.

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.

A printer has a carriage being movable between a first end and a second end of a reciprocating path; and a driving force transmitting path selecting mechanism provided at the second end of the reciprocating path. The selecting mechanism has: a common driving force outputting member; a plurality of force receiving members; a selecting member; and a position retainer for keeping the position of the selecting member. The selecting member connects the force outputting member to one of the plurality of force receiving members, and moves in association with the carriage when the carriage moves in a vicinity of the second end in a first direction extending from the first end to the second end. The position retainer keeps the position of the selecting member when the carriage moves in a second direction extending from the second end to the first end. The force receiving member connected to the force outputting member via the selecting member is selected in accordance with a movement of the carriage along the reciprocating path.
