The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The suction unit causes the conveyance belt to suck the sheet. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A ratio of the recessed portions per unit area in a facing region of the conveyance plate facing the head end portion is smaller than a ratio of the recessed portions per unit area in a region other than the facing region.

A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device comprises a movable support surface to transport a print medium along a process direction through the deposition region, the media transport device holding the print medium against the movable support surface by vacuum suction. The air flow control system is arranged to selectively flow air through the opening of the carrier plate between the carrier plate and the printhead based on a location of a print medium transported by the media transport device relative to the printhead.

A liquid discharge apparatus includes a stage on which a recording medium is placed, a head configured to discharge a liquid onto the recording medium on the stage, an inclined wall adjacent to the recording medium, the inclined wall configured to cover a part of the stage, and a height adjuster configured to adjust a height of one end of the inclined wall to be equal to or lower than a thickness of the recording medium.

A sheet suction device includes a drum having multiple suction ports in a circumferential surface of the drum, the drum configured to bear a sheet on the circumferential surface and rotate in a circumferential direction of the drum, and a suction device configured to suck the sheet through the multiple suction ports to attract the sheet on the circumferential surface. The drum includes multiple suction regions aligned in the circumferential direction on the circumferential surface, each of the multiple suction regions includes the multiple suction ports aligned in the circumferential direction and in an axial direction of the drum on the circumferential surface, the multiple suction regions include an upstream region, a middle region, and a downstream region in the circumferential direction, and the middle region has the multiple suction ports at both outer sides in the axial direction of the drum.

A drop-on-demand plastic card printer includes a tray disposed underneath the plastic card during drop-on-demand printing to catch any overspray that may occur during printing on the plastic card. The tray may be disposable so that the tray is intended to be removed and disposed of. An ink absorbent pad can be disposed in the tray to absorb the oversprayed ink. The ink absorbent pad can be disposed of along with the tray or disposed of separately from the tray.

The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.

A suction apparatus includes a support portion, a plurality of suction holes formed in the support portion, a suction mechanism configured to perform suction from an outer side of the support portion toward an inner side through the plurality of suction holes, a lighting unit provided on the inner side of the support portion for each region of the support portion, a light transmitting portion configured to transmit light emitted by the lighting unit to the outer side of the support portion, and a control unit configured to control the lighting unit, in which the control unit makes a lighting state of the lighting unit corresponding to a suction region in which suction at the support portion is enabled different from a lighting state of the lighting unit corresponding to a non-suction region in which the suction at the support portion is disabled.

A printer includes: a conveyor conveying a sheet in a conveying direction; a first supporting part positioned on an upstream side in the conveying direction with respect to the conveyor, and having a first supporting surface; a side guide making contact with at least one of both ends, in a width direction of the sheet, in the first supporting surface, the width direction being orthogonal to the conveying direction and parallel to the first supporting surface; a suction-attraction force generator generating a suction-attraction force in an area, in the first supporting surface, which is adjacent to the side guide and in which the sheet passes; a second supporting part positioned on a downstream side in the conveying direction with respect to the conveyor, and having a second supporting surface; and a recording part recording an image on the sheet supported by the second supporting surface.

In one example, a system to support print media through a print zone in a printer includes an endless support belt, a driver to circulate the support belt through the print zone, and an encoder unit under the print zone to measure movement of the support belt in the print zone.

In one example, a system to convey print media through a print zone in a printer includes an endless conveyor belt in a loop, a pair of drivers to circulate the conveyor belt through the print zone from opposite ends of the loop, an encoder to measure movement of the conveyor belt, and a controller programmed to control both drivers driving the conveyor belt based on measurements from the encoder.
