A recording apparatus includes a carriage, a tank, a flow passage, and a valve. The carriage includes a recording head that ejects liquid contained in the tank and supplied from the flow passage. The flow passage includes (i) a fixed flow passage connected to the tank without following a movement of the carriage, (ii) a first flow passage that follows the movement of the carriage and is branched off from the fixed flow passage and connected to the recording head, and (iii) a second flow passage that follows the movement of the carriage and is branched off from the fixed flow passage and connected to the recording head. The valve is provided in one of the first and second flow passages and limits a flow of liquid from the tank to the recording head and allows liquid to flow from the recording head to the tank.

Recording apparatus

The carriage apparatus includes a carriage configured to reciprocally move in a first direction, a first motor arranged on a side of one end of a range of movement of the carriage and configured to drive the carriage, a second motor arranged on a side of the other end of the range of movement of the carriage and configured to drive the carriage, a carriage belt suspended between the first motor and the second motor, attached with the carriage, and configured to move the carriage in the first direction, and a support portion configured to mount the second motor so that the second motor is displaceable in the first direction with respect to the first motor.

Carriage apparatus and printing apparatus

A recording apparatus includes a carriage, a tank, and a flow passage. The carriage includes a liquid ejecting recording head and reciprocates in first and second directions. The flow passage supplies liquid from the tank to the recording head, and includes a fixed flow passage, a first flow passage, and a second flow passage. The fixed flow passage is connected to the tank and does not to follow a movement of the carriage. The first flow passage is branched off from the fixed flow passage, is connected to the recording head in the first direction, and follows the carriage movement. The second flow passage is branched off from the fixed flow passage, is connected to the recording head in the second direction, and follows the carriage movement. After the carriage moves in the first direction, stops, and moves in the second direction, liquid is sucked from the recording head.

Recording apparatus and control method therefor

A printing apparatus includes a carriage mounted with a printing unit configured to perform printing on a print medium, a first motor used to move the carriage, a second motor used together with the first motor to move the carriage, and a control unit configured to control the first motor and the second motor. When moving the carriage, the control unit controls the first motor with a first control amount and controls the second motor with a second control amount. The first control amount and the second control amount are different from each other, and a ratio therebetween is a predetermined ratio.

Printing apparatus, carriage apparatus, and control method

A printing apparatus includes a carriage mounted with a printing unit, a belt, a first motor configured to drive the belt at one end in a widthwise direction, a second motor configured to drive the belt at the other end in the widthwise direction, and a control unit configured to control the first motor and the second motor. The control unit performs first control by driving the first motor in which the carriage moves from a state in which the carriage is stopped. In the control, the second motor is controlled from a first state in which its torque is lower than that of the first motor to a second state in which its torque is higher than that in the first state.

Printing apparatus and carriage apparatus

A printing apparatus includes a carriage mounted with a printing unit; a first motor configured to move the carriage in a predetermined direction; a second motor configured to move the carriage in the predetermined direction; and a control unit. The control unit executes a first mode in which, when causing the printing unit to perform printing under a first printing condition, the first motor is driven in a first direction and the second motor is driven in the first direction, and a second mode in which, when causing the printing unit to perform printing under a second printing condition different from the first printing condition, the first motor is driven in the first direction and the second motor is driven in the first direction while changing an output ratio between the first motor and the second motor.
