An inkjet recording device has a head base, a head unit, and an adjustment mechanism. The adjustment mechanism has a guide screw, a moving member, the operation member for rotating the moving member, and an adjusting member. The moving member has a shaft hole screwed into the guide screw, and moves in an axial direction of the guide screw by rotating with respect to the guide screw. The adjusting member has a first contact portion in contact with the moving member and a second contact portion in contact with the head unit. The second contact portion moves in a direction toward the head unit and a direction away from the head unit, by moving the moving member in contact with the first contact portion in the axial direction of the guide screw.

Embodiments of the disclosure provide for improved print position compensation, for example to improve accuracy of print job(s) performed by a printer. The print position compensation enables an offset of the time until printing occurs on a print media to account for changes and/or erroneous movement in a print media, such as due to slippage and/or other results of a force applied to the print media. Particular embodiments determine data values derived both for an output phase and a retraction phase of the printer's operation. Various embodiments generate a print position compensation based on sensor-based edge position distances determined during each of a media output phase and a media retraction phase. Alternatively or additionally various embodiments generate a print position compensation based on sensor-based media movement phase timestamp differentials determined during each of a media output phase and a media retraction phase.

A printing apparatus includes a carrying platform on which a substrate is placed, a cartridge configured to store and supply ink, and a print head configured to atomize the ink into ink droplets and deposit the ink droplets on a printing region of the substrate.

There is provided a printing apparatus which includes the following: A printhead including a plurality of nozzles that discharge ink to a print medium. A first detection unit that detects a distance between the printhead and a platen. An adjustment unit that adjusts the distance between the printhead and the platen. An acquisition unit that acquires difference information concerning a difference of a distance between the platen and each of the nozzle on an upstream side and the nozzle on a downstream side in a conveyance direction of the print medium. The adjustment unit adjusts the distance based on a detection result of the first detection unit and the difference information acquired by the acquisition unit.

An example printing apparatus is illustrated. The printing apparatus includes a print engine assembly. The print engine assembly further includes a bottom chassis portion. The print engine assembly also includes a top chassis portion. The print engine assembly also includes a print head positioned within the top chassis portion. The print engine assembly also includes a plurality of offset pins coupled to the print head, where the plurality of offset pins abuts the bottom chassis portion, and where the plurality of offset pins enables the print head to be positioned at a predetermined distance from the bottom chassis portion.

A liquid discharge apparatus includes a recording device and a recording controller. The recording controller alternately performs a main scanning control and a sub-scanning control. The main scanning control controls discharging liquid while moving the recording device and a recording medium relative to each other in a main scanning direction. The sub-scanning control controls the recording device to discharge the liquid from at least two recording elements of the recording device, in accordance with at least two times of the main scanning control performed at positions on the recording medium in a sub-scanning direction. The recording device discharges the liquid, within a range in the sub-scanning direction corresponding to a position of the recording head. The recording controller performs the main scanning control for discharging the liquid based on discharge order mask patterns different from each other in a plurality of regions in the main scanning direction.
