An inkjet printer is provided that is configured to store a plurality of pieces of gap information respectively corresponding to a plurality of examined sections discretely arranged along a head moving direction on a recording sheet, each of the plurality of examined sections including a corresponding one portion of top portions and bottom portions on the recording sheet, and calculate interpolation gap information to be interpolated over a whole width in the head moving direction of at least one of a plurality of segments, each of which has a width in the head moving direction defined by two adjacent sections of the plurality of examined sections, based on the stored gap information.

A printer includes a printing unit which performs printing on a sheet and which discharges a printed sheet from a discharging opening, and a pair of body-side feet disposed on both sides in a width direction of a sheet to be discharged from the discharging opening. A sheet housing apparatus includes a housing unit which houses a sheet to be discharged from the discharging opening, and a pair of housing-side feet disposed on the both sides in the width direction. The sheet housing apparatus can be mounted from a predetermined mounting direction to the printer. The body-side feet and the housing-side feet are arranged to be disposed, in a state in which the sheet housing apparatus is mounted to the printer, so as to overlap with each other in the mounting direction and not to overlap with each other in the width direction.

An ink jet printing device for customized printing of images on a face of a sheet material includes a frame with a top surface defining a running plane for a face of the sheet material, with guides transverse to the running direction of the material, a printing unit that can move along the guides and has a printing head therein, a supply source supplying the printing head with printing ink, and a movement system driving the printing unit along the guides. The printing head faces the running plane for depositing the ink on the sheet material, and the supply source includes a secondary reservoir, mounted in the printing unit and in fluid connection with the head, and a main reservoir in fluid connection with the secondary reservoir for refilling the secondary reservoir and maintaining the level of ink above a predetermined threshold value, ensuring supply to the printing head.

A printer having a printhead configured to print to a print medium; a camera configured to photograph the print medium; a carriage configured to support and move the printhead and the camera; and a processor configured to print, by the printhead, on the print medium a first test pattern that is larger than an imaging area of the camera, photograph the first test pattern by the camera, and detect a printing defect based on a result of the photograph.

A liquid discharging apparatus includes a print head that discharges a liquid, a carriage that is mounted on the print head, a control signal generation circuit, a drive signal generation circuit, a first cable through which a drive signal generation control signal is transmitted to the drive signal generation circuit, a second cable through which a drive signal is transmitted to the print head, a control circuit substrate on which the control signal generation circuit is provided, and a drive circuit substrate on which the drive signal generation circuit is provided. The shortest distance between the control circuit substrate and the carriage is longer than the shortest distance between the drive circuit substrate and the carriage. The drive circuit substrate is provided at a position where a region in which the carriage moves and at least a part of the drive circuit substrate overlap each other.

A printing apparatus including a transport guiding portion with high manufacturing yield, is provided. A printing apparatus includes a printing portion which is able to print on a medium, a transport portion which transports the medium, and a transport guiding portion on which a transport surface on which the medium is transported is formed and which has a plurality of bent portions, in which the transport guiding portion is provided with a first guiding member which has a bent portion and forms the transport surface on a transport direction upstream side of the medium and a second guiding member which has a bent portion and forms the transport surface on a transport direction downstream side of the medium.

An inkjet printing method with an inkjet printing device includes a vacuum belt having a set of air-channels connecting a top-surface and a bottom-surface of the vacuum belt. The set of air-channels couples an inkjet receiver to the vacuum belt by air suction in the set of air-channels, wherein the vacuum belt includes a dimple at the top-surface. The dimple has a closed bottom end, and wherein the dimple is connected with an air-channel of the set of air-channels to form an air cup and to couple the inkjet receiver to the vacuum belt at the dimple by air suction.

A printer comprising: a fixed printhead assembly defining a print zone; an input transport assembly for feeding print media along a media path and into the print zone, the input transport assembly being positioned upstream of the print zone; and an exit transport assembly positioned downstream of the print zone for receiving the print media from the print zone. The input transport assembly exerts a higher gripping force on the print media than the exit transport assembly and the exit transport assembly is configured to provide a higher transport speed than the input transport assembly, such that the print media has a degree of slippage relative to the exit transport assembly.

Examples described herein include devices and methods for adjusting a suction force for a media holddown, comprising detecting an advancement of a media (114) relative to a media holddown surface along a media advancement direction (X), wherein the holddown surface has a plurality of suction zones arranged along the media advancement direction, and adjusting a suction force in the respective suction zones in accordance with the advancement of the media relative to the media holddown surface.

An inkjet printing device includes a vacuum flatbed table configured to support large and flat substrates with applied vacuum power and while printing, in a hold down area, against the vacuum flatbed table; a removable flat substrate support device configured to support large and flat substrates while printing; and a vacuum belt connected to a plurality of pulleys and wrapped around the vacuum flatbed table; wherein the vacuum flatbed table is configured for coupling the removable flat substrate support device stationary to the vacuum flatbed table by applied vacuum power; and the vacuum belt is sandwiched between the removable flat substrate support device and the vacuum flatbed table.
