Jetted material printer with pressure-assisted fluid extraction

A three-dimensional (3D) inkjet printer is configured to build up an object by printing a series of layers and stacking them to form the object. In order to speed printing, drying of each layer is accelerated by using a pressure differential to extract liquid vehicle from the ink, and by moving the printed layer away from the inkjet print heads before drying so that the inkjet print heads may print the next layer. The dried printed layer may also be conditioned and/or cured. Dried printed layers are stacked at a build station to assemble the finished object.

20230173829 · 2023-06-08 · ·

A printing device comprises a housing, a print head provided in the housing, a mount to which a roll body is detachably mounted, a conveyor configured to convey a printing medium unwounded from the roll body along a conveying path including an upstream path extending from the mount to the print head, and a cutter configured to cut the printing medium at a particular position in the upstream path. The roll body is a sheet type printing medium wounded into a rolled-up state. The conveyor comprises a holder arranged, in the upstream path, at a position between the cutter and the print head. The holder is configured to hold the printing medium in a state where the printing medium is deformed to be corrugated along a direction perpendicular to the conveying direction.

An inkjet recording device includes: an inkjet head that includes a nozzle for discharging ink on a recording material, and forms an image by discharging the ink from the nozzle on the recording material based on image data; and a hardware processor that performs image processing of the image data, wherein the hardware processor calculates a difference in ink adhesion amount between a target region and an adjacent target region adjacent to the target region in the image data, determines whether the difference in the ink adhesion amount exceeds a threshold based on a calculation result of the hardware processor, and performs a responding process for occurrence of a wrinkle on the recording material based on a determination result of the hardware processor.

Drying apparatus, printing system and drying method that inject hot wind from nozzles to surface of recording medium

In the air-blow dryers 7a, 7b, the back surface M2 of the printing medium M is supported by the rollers 74 while the hot wind is injected from the nozzles 76u to the front surface M1 of the printing medium M. By extending the printing medium M along the rollers 74, the evaporation of the moisture can be promoted by the hot wind while the formation of creases of the printing medium M is suppressed against the influence of the temperature distribution caused by the latent heat of the moisture on the printing medium M. After a certain amount of the moisture is evaporated, the temperature of the printing medium M becomes relatively uniform. In the air-blow dryers 7c, 7d, the printing medium M is dried by injecting the hot wind to the printing medium M from the nozzles 76l and 76u from both sides.

09772594 · 2017-09-26 · ·

A curl correcting device includes a pair of fixed guides and a change-over guide. The pair of fixed guides composes a curved part of a conveyance path. The change-over guide is provided to be contactable with a sheet from a radial outer side of the curved part. An outer guide includes a pair of side pressing parts and a bulge part. The pair of side pressing parts is formed at both ends in a width direction. The bulge part is formed between the pair of side pressing parts so as to bulge toward the radial outer side of the curved part. The change-over guide is configured to move to a first correcting position when the sheet curled along the conveyance direction is conveyed through the conveyance path and to move to a second correcting position when the sheet curled along the width direction is conveyed through the conveyance path.

The present disclosure relates to a printer for pulling out a paper wound in the form of a wound roll, and more particularly, to a printer which includes a cartridge configured to accommodate the paper, a housing in which the cartridge is mounted, and a printing part configured to pull out the paper. The cartridge or the housing has a decurling part formed thereon, and the decurling part comes into surface-contact with the paper on the upper side of the paper in the process of pulling out the paper.

Image forming apparatus

A first light emitter emits light toward a sheet. A first light receiver receives first reflected light from the sheet. A second light emitter is arranged downstream of the first light emitter in a conveyance direction of the sheet and emits light toward the sheet. A second light receiver receives second reflected light from the sheet. A measuring section measures first and second received light quantities of the first reflected light and the second reflected light. A moisture content calculator calculates a change in a moisture content of the ink in the sheet based on a difference between first and second moisture contents. The first moisture content is based on the first received light quantity and the second moisture content is based on the second received light quantity. A curling amount calculator calculates a curling amount of the sheet based on the change in the moisture content.

Decurling device and image forming apparatus

A decurling device includes: a first transport unit including a transport roller, the first transport unit that sandwiches a transported sheet and transports the transported sheet further downstream; and a second transport unit including an endless belt that is in contact with the transport roller. The transport roller has an elasticity that, when the belt is pressed against the transport roller, allows the belt to bite into the transport roller by a bite amount corresponding to a pressing force, the second transport unit includes an abutting member disposed inside the belt, the abutting member pressing the belt from an inside of the belt and causing the belt to abut against the transport roller, and a guide member, the abutting member includes an upstream protrusion, an downstream protrusion, the upstream protrusion and the downstream protrusion being provided at positions away from each other at an upstream portion and a downstream portion in a sheet transport direction, each of the upstream protrusion and the downstream protrusion protruding toward an inner surface of the belt, and a recess provided in an intermediate portion between the upstream protrusion and the downstream protrusion in the sheet transport direction, the recess being recessed away from a straight line connecting a top portion of the upstream protrusion and a top portion of the downstream protrusion, the guide member includes a contact surface that is in contact with the inner surface of the belt, the contact surface defining a part of a circulation track of the belt, and the upstream protrusion protrudes beyond a virtual circle that is tangent to the contact surface.
