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.

An inkjet printer is described. The inkjet printer has a gas cushion substrate support having a metal support surface; a print assembly with a dispenser having ejection nozzles facing the support surface; a gas source fluidly coupled to the gas cushion substrate support by a gas conduit; and a thermal control system coupled to the gas conduit.

Disclosed herein is an adhesive belt for use in a printing device, a printing device, and a method of operating a printing device. The adhesive belt is to be placed around a conveyer belt of a printing device. The adhesive belt comprises a contact surface that is to come in contact with a print medium, wherein the contact surface comprises a dry adhesive material. The adhesive belt further comprises a fastener that is to open and close the adhesive belt by reversibly joining opposing end portions of the adhesive belt.

Disclosed are printer vacuum tables, and corresponding systems and methods for their use, in which the printer vacuum tables include multiple zones to apply vacuum, to hold a variety of media types and thicknesses within a given flatness range, to allow high definition printing. The vacuum zones run in the print direction, and each can be controlled for vacuum on and off. In an illustrative embodiment, the vacuum zones include one or more vacuum zones that are fixed with respect to a printer vacuum table surface, and one or more variable vacuum zones that are movable with respect to the printer vacuum table surface. One or more of the vacuum zones can be turned off if the print media does not cover the zone, such as to prevent leakage, and to provide more consistent vacuum hold down, regardless of media size or width.

A holder assembly includes a base, a drive assembly coupled to the base, a motive source connected to the drive assembly, a vertical force applicator connected to the drive assembly along a connection edge thereof, and a gripping member coupled to the base, the gripping member having a contact surface coupled to a vacuum source, wherein the drive assembly has a first position with the flattening member engaged with the contact surface and a second position with the flattening member positioned away from the contact surface.

A liquid ejecting apparatus includes a liquid ejecting unit which can eject liquid; a connection unit to which a liquid container is connected along with a movement of the liquid container which can accommodate the liquid in a connecting direction; and a position adjusting unit which can change a position of the liquid container which is connected to the connection unit in a direction which intersects the connecting direction.

Embodiments of the invention take advantage of the change in gloss caused by overprinting a printed image with clear ink. Embodiments of the invention thus implement gloss control functionality in a printer without the requirements of a pin and cure or other known systems.

A medium feeding apparatus includes a feeding roller which feeds a printing medium, a roll holding portion which holds a roll body around which the printing medium is wound, an intermediate roller which pulls out the printing medium from the roll body and feeds the printing medium to the feeding roller, and a controller which synchronizes and controls driving of the feeding roller and the intermediate roller, in which the controller sets a target value in a driving control of the intermediate roller to be greater than a target value in a driving control of the feeding roller, so that tension is not applied to the printing medium between the feeding roller and the intermediate roller, when the feeding roller and the intermediate roller feed the printing medium.

The invention relates to a printing assembly which has print heads, each of which specifies application positions for printing fluid. A transport path is provided for the printing substrate through the printing assembly and is defined by at least two guide elements of the printing assembly. A printing section of the transport path begins at a first application position and ends at a last application position. At least one of the guide elements is in contact with a total of at least two lateral support elements and with at least one inner support element at three points that are spaced from one another in a transverse direction, the position of that guide element being thereby defined. The inner support element is arranged such that it is or can be rigidly connected to at least one of the lateral support elements. The lateral support elements can be embodied as part of a support frame, which support frame has at least one cross-member that is different from the guide elements, that at least one cross-member extending in the transverse direction and ensuring a constant relative positioning of the lateral support elements.

The disclosed embodiments relate to a wide format single pass printing apparatus. The printing apparatus can include multiple print housings configured to receive print beams with print heads configured to print onto a substrate. The print housings can be horizontally adjacent to one another relative to a horizontal plane. The print housings can also be oriented opposite to one another. The print beams can be inserted and/or removed from each print housing from opposing ends, allowing for greater ease of access to the print beams.
