A liquid discharge apparatus includes a conveyance roller, a liquid discharge head, and a control device. The control device controls the head to discharge liquid onto a medium X times in the main scanning direction and Y times in the sub-scanning direction and controls the roller such that a position of a droplet on the medium discharged by an m-th discharge and a position of another droplet on the medium discharged by an (m+Y)-th discharge are same in the sub-scanning direction, where m is an integer not smaller than one and not greater than ((X−1)×Y). Where P is a circumferential length of the roller and L is a difference in a conveyance distance in the sub-scanning direction when the m-th discharge is compared with the (m+Y)-th discharge, the following relation is satisfied:

L=(n+(Δθ/2π))×P,

where |π−Δθ|<60° and n is an integer.

A printing apparatus includes: a head portion that discharges droplets toward a printing medium while reciprocating on the printing medium; and a controller that controls movement of the head portion during a printing operation such that a movement stop time of the head portion when a movement direction of the head portion is reversed at an endmost portion of a range in which the head portion moves is longer than the movement stop time of the head portion when the movement direction of the head portion is reversed on the printing medium.

A printing apparatus includes a head configured to discharge liquid to a printing medium, a carriage configured to move the head back and forth to one side and another side in a scanning direction with respect to the printing medium, and a control unit configured to perform printing of a printing image with the liquid by controlling driving of the head and the carriage. When performing printing of an end portion of the printing image on the one side, the control unit performs the printing by a first scan in which the head is moved from the one side to the other side, and when performing printing of an end portion of the printing image on the other side, the control unit performs the printing by a second scan in which the head is moved from the other side to the one side.

A controller determines: based on image data, whether both a code image and a non-code image are included in an image to be recorded in a passing region of a recording medium; and in response to determining that both images are included, during a first relative movement of a head, performs first separate recording processing of controlling the head and a motor to record at least part of a portion of the code image included in the passing region without recording a portion of the non-code image included in the passing region; and during a second relative movement which is performed after the first relative movement, performs second separate recording processing of controlling the head and the motor to record at least part of the portion of the non-code image included in the passing region without recording the portion of the code image included in the passing region.

A liquid discharging apparatus, having a liquid discharging head, a relatively-movable device, and a controller, is provided. The controller controls the liquid discharging head and the relatively-movable device to record a plurality of relative movement adjuster patterns, arranged at different positions in an arrayed direction, and a different pattern, arranged side by side with the plurality of relative movement adjuster patterns along a direction orthogonal to an arrayed direction on a same liquid-discharge objective medium. The controller controls the relatively-movable device, after recording at least one of the plurality of relative movement adjuster patterns, and before recording a next one of the plurality of relative movement adjuster patterns next to the at least one of the plurality of relative movement adjuster patterns, to perform a relative moving action by a moving amount different from a predetermined relative moving amount for recording the different pattern at least once.

It is disclosed a carriage, e.g., for a printing system comprising a housing being the carriage to move along a carriage guide, the carriage comprising a drive mechanism attached to the carriage. The drive mechanism comprises a motor having a rotating axis and an intermediate element attached to the rotating axis, being the intermediate element to contact the carriage guide as to move the carriage along the carriage guide.

An image recording apparatus includes: a casing having an internal space; a conveying passage formed inside the casing; a first roller pair positioned in the conveying passage, having a driving roller and a driven roller, and configured to pinch a sheet and to convey the sheet in a conveying orientation; a platen positioned on a downstream side in the conveying orientation of the first roller pair, and having a supporting surface supporting the sheet; a recording part positioned above the platen and configured to record an image on the sheet supported by the platen; a second roller pair which is located on the downstream side in the conveying orientation of the supporting surface of the platen, and which is configured to pinch the sheet and to convey the sheet; and a moving mechanism configured to move the platen to a printing position and to a release position.

There is provided a liquid discharge apparatus which includes a tank including a liquid storage chamber, an inlet, a liquid lead-out channel, and an atmosphere communication channel, a conveyance mechanism, a carriage, and a head. A lower end of the inlet is positioned at a lower side of the nozzles, and the liquid storage chamber is arranged at a position shifted from the nozzles, in a first-direction side of the front-rear direction, and shifted from the conveyance route, to a second-direction side of the left-right direction. The liquid storage chamber is connected to the liquid outflow channel at a position on a lower side of a center in a up-down direction of the liquid storage chamber, and in the first direction from a center in the front-rear direction of the liquid storage chamber, and on the second-direction side of a center in the left-right direction of the liquid storage chamber.

A liquid discharge apparatus includes: a discharge head including nozzles; a head scanning mechanism that reciprocatingly moves the discharge head in a main scanning direction; a conveyor that conveys a recording medium in a sub-scanning direction; and a controller. In one pass, the controller executes: recording processing in which an image is formed on the recording medium by moving the discharge head in the main scanning direction and discharging liquid from the discharge head; setting processing in which the discharge head moves to a starting position of the recording processing for a subsequent pass following the one pass by changing a moving direction of the discharge head at a standstill position; and conveyance processing in which the recording medium is conveyed in the sub-scanning direction.

A printing apparatus includes a discharge head configured to discharge a liquid toward a medium, a head control board configured to control the discharge head, a circuit case having a box-like shape configured to house the head control board, and a carriage configured to reciprocate in a scanning direction while supporting the discharge head and the circuit case. The circuit case includes an air intake port in one surface of the circuit case, with the one surface intersecting with the scanning direction, and an exhaust port in another surface of the circuit case, with the other surface intersecting with the scanning direction. At the exhaust port, an exhaust fan configured to exhaust, to outside of the circuit case, heat that is inside the circuit case is installed, the heat being generated by the head control board.
