A carriage is configured to move by receiving driving force from a carriage motor. A recording head is mounted on the carriage. A controller is configured to: control a power supply to supply a first driving current to a drive target, the first driving current being variable; when a second driving current for driving the carriage motor does not exceed a limiting current, control the power supply to supply the second driving current to the carriage motor, the second driving current being variable, the limiting current being obtained by subtracting the first driving current from an allowable current of the power supply; and when the second driving current exceeds the limiting current, control the power supply to supply a limited second driving current to the carriage motor, the limited second driving current being obtained by cutting a part of the second driving current, the part exceeding the limiting current.

A printing apparatus includes an ejection unit including a nozzle surface configured to eject a liquid droplet, the nozzle surface facing a printing surface of a medium, a transport unit configured to transport the medium in a transport direction, a steam application unit configured to apply steam to the printing surface, the steam application unit being provided upstream of the ejection unit in the transport direction, and a medium compression unit configured to compress the medium, the medium compression unit being provided upstream of the ejection unit in the transport direction and downstream of the steam application unit in the transport direction.

A printing apparatus includes a head to discharge liquid, a carriage to support the head and reciprocate in a forward direction and a backward direction, and a controller. The controller executes a printing process to print one image in a plurality of copies by discharging the liquid from the head while moving the carriage in the forward direction and the backward direction, based on a print job for printing the one image in the plurality of copies, and a first determining process to determine a moving direction of the carriage for second and following copies, based on a moving result of the carriage in printing for the first copy in the printing process.

There is provided control system including: movement mechanism configured so that the movement mechanism is driven by motor; detector configured to detect position and speed of the movable member; and controller. The controller is configured to: control the motor so that the movement mechanism reciprocatively moves the movable member; and in a course to move the movable member to a returning point, control the movement of the movable member by controlling the motor based on the speed of the movable member so that the movable member is moved at a constant speed until a deceleration start point of time, and control the movement of the movable member by controlling the motor based on the position of the movable member so that the movable member is decelerated from the deceleration start point of time and stops at the returning point in accordance with a target position locus.

A control unit configured to perform multi-pass printing provided that a region of a printing medium including a first region, a region downstream of the first region is a second region, and a region downstream of the second region is a third region, in a first period in which the first region is a target of printing, causes a velocity of paper feed to be slower than in a third period in which the third region is a target of printing; in the first period, causes a standby time of the printing head to be longer than in the third period; and in a second period in which the second region is a target of printing, changes the standby time so that the standby time approaches the standby time in the first period from the standby time in the third period as the first region approaches the printing head.

There is provided control system including: movement mechanism configured so that the movement mechanism is driven by motor; detector configured to detect position and speed of the movable member; and controller. The controller is configured to: control the motor so that the movement mechanism reciprocatively moves the movable member; and in a course to move the movable member to a returning point, control the movement of the movable member by controlling the motor based on the speed of the movable member so that the movable member is moved at a constant speed until a deceleration start point of time, and control the movement of the movable member by controlling the motor based on the position of the movable member so that the movable member is decelerated from the deceleration start point of time and stops at the returning point in accordance with a target position locus.

In one example, a printing device may include a first motor to transition a carriage between a first position and a second position, the carriage to exert a force on a gate shifter as the carriage transitions between the first position and the second position, the gate shifter to transition between an open position and a closed position in response to the exerted force of the carriage, and a feed swingarm to transition between a first side and a second side of the gate shifter when the gate shifter is in the open position.

A movement mechanism for a movable body including a motor including a rotation shaft, a supporting member that supports the motor, an attachment member fixed to a base body portion and to which the supporting member is attached, a driving pulley coupled to the rotation shaft, a driven pulley attached to the base body portion, an endless belt stretched between the driving pulley and the driven pulley, and the movable body attached to the endless belt, in which the supporting member is configured to be pivotally movable about a position serving as a pivotal axis such that a distance between the driving pulley and the driven pulley shortens, the position being at a side of the driven pulley from the driving pulley in a stretching direction in which the endless belt is stretched between the driving pulley and the driven pulley.

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.

Provided is a printing device that includes a Y-axis encoder outputting a pulse signal corresponding to a position of a head part in a predetermined direction, a Y-axis counter counting a count value based on the pulse signal from the Y-axis encoder, a control part that performs a first and a second controls, and a determination part determining that the Y-axis encoder is normal when a count value equal to or greater than a predetermined number is counted and determines that the Y-axis encoder is abnormal when a count value less than the predetermined number is counted in the first control. The control part shifts from the first control to the second control when the Y-axis encoder is determined to be normal, and the control part does not shift from the first control to the second control when the Y-axis encoder is determined to be abnormal.
