An air fan assembly includes a suction box including a wall having an open area distributed across the wall. The suction box is configured to contain an underpressure on an inner side of the wall, so as to cause a cut sheet to adhere to a perforated transport belt. An impingement unit is configured to expel air supplied thereto towards the perforated transport belt. An air fan is arranged to create and maintain the underpressure in the suction box and to supply the air to be expelled by the impingement unit via an air outlet of the suction box. A first valve is arranged upstream of the air fan for conditionally admitting an additional air flow into the suction box. An inkjet printer and a method of operating the air fan assembly include the air fan assembly.

An arrangement in communication with a printer. The printer includes at least a print-head configured to deposit liquid ink on an area on a surface of a substrate. The liquid ink comprises a solvent portion and a dry content. The arrangement comprises at least one nozzle configured to generate a stream of gas over said area with a gas stream velocity and/or gas stream shape, such that an evaporation rate of the solvent portion of the liquid ink is increased and a rate of change of velocity of the gas stream propagation increases with a distance normal to a direction of a gas flow and is maximized over the surface of the substrate and the deposited ink.

A printing apparatus, such as a large-scale ink jet printer, includes two removable, interchangeable dryer modules, which may be operated separately or in series. Each dryer module permits a sheet or web to pass therethrough in a process direction. Each dryer module includes a lamp mount, suitable for holding one or more heating or curing lamps, the lamp mount being slidably disposed within the module for easy access to the lamps. Each dryer module defines a top portion suitable for maintaining an airflow above the lamp mount, and a bottom portion suitable for maintaining an airflow below the lamp mount. A plate having a pattern of openings therein enables an airflow through the lamps.

The invention relates to an apparatus (1) for irradiating a substrate (2), which apparatus comprises a platform (4), which is straight or curved in relation to the longitudinal axis (3) of the platform (4), wherein one, two, three, four, five, six, seven, eight, nine, ten or more irradiation modules (6) and/or substrate supply air modules (36) and/or substrate exhaust air modules (37) are reversibly attachable directly or indirectly to the bottom side (8) of the platform (4) by sliding or inserting or mounting in one or more fixed or telescoping module attachment devices (10) provided on the bottom side (8) of the platform (4) - each extending from the front side (5) of the apparatus (1) and in the direction of the back side (9) of the apparatus (1).

A conveying device includes a blower, a wind-permeable sheet material supporter, and a conveyor. The blower blows air toward a sheet material. The sheet material supporter supports a center region of the sheet material from a back side of a blown surface of the sheet material. The conveyor conveys the sheet material through a blowing region blown by the blower, while sandwiching an end region of the sheet material in a sheet-material width direction perpendicular to a sheet-material conveyance direction in which the sheet material is conveyed by the conveyor.

A recording method is a method including an adhesion step of adhering an ink composition to a recording medium, in which the recording medium is a low-absorbing recording medium or a non-absorbing recording medium, the adhesion step is performed by scanning that is carried out by jetting the ink composition from an ink jet head to make the ink composition adhere to the recording medium while moving relative positions of the ink jet head and the recording medium, the scanning is performed seven times or less on an identical region of the recording medium, the ink composition is an aqueous ink containing a coloring material and a silicone-based surfactant A, and a maximum peak of the silicone-based surfactant A in a molecular weight range of 300 or greater is present in a range of 3000 to 20000 in a molecular weight distribution obtained by gel permeation chromatography.

A liquid discharge apparatus is provided that includes a transport unit configured to transport a medium, a discharge unit configured to discharge a liquid onto the medium, a housing including therein the discharge unit, a humidifying unit configured to humidify an interior of the housing, and a humidity detection unit configured to detect a humidity. When the humidity detection unit detected a humidity less than a lower limit value (one example of a first predetermined value) (positive determination in step S12), the interior of the housing is humidified by the humidifying unit during transport by the transport unit or during discharge by the discharge unit (step S16).

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.

Provided is a liquid ejecting device. An alternating current electric field generation unit includes a first electrode and a second electrode disposed adjacent to each other, a high-frequency voltage generation unit configured to generate a high-frequency voltage to the first electrode and the second electrode, and a conductor configured to electrically couple the first electrode and the second electrode to the high-frequency voltage generation unit. The first electrode and the second electrode are disposed upstream of a liquid ejecting head in a transport direction of a medium.

A recording device includes a transport unit configured to alternately repeat transport and stop of a recording medium, a recording head configured to discharge ink onto the recording medium to form an image while the recording medium is stopped in an image forming region, a drying unit including a plate in which a plurality of openings for blowing an air flow are formed in a position facing the recording medium transported by the transport unit, and being configured to dry the recording medium on which an image is formed by the recording head, and a relative movement unit configured to move the recording medium and the plate relatively in an intersecting direction that intersects a facing direction in which the recording medium and the plate face each other, while the recording medium is stopped in the image forming region.
