A drying assembly is disclosed. An example apparatus includes fans; a temperature sensor; a print engine to access instructions to cause a printer to perform a printing operation on media; and a processor responsive to an output of the temperature sensor to control the fans to force air onto the media to cause a substantially uniform temperature to be maintained across a width of the media during the printing operation and to cause a sum of air flow output by the fans to be maintained at a substantially constant value.

A recording system includes a transportation unit that transports a paper sheet, an ejection unit that ejects an ink, a heating unit that heats the paper sheet, a discharge unit to which the paper sheet is discharged, and a control unit. The control unit specifies an amount of ejection of the ink from the ejection unit. The control unit also controls an operation of the heating unit such that an undried region where the ink on the paper sheet is not dried and a dried region where the ink on the paper sheet is dried are formed on the paper sheet. Then, the control unit controls a transporting operation by the transportation unit such that the paper sheet on which the dried region and the undried region are formed is discharged to the discharge unit.

A method is provided for printing a surface of a non-absorbent substrate with an ink to be applied by an inkjet printing device. An ink that contains water as a solvent is used for printing the substrate. An ink having a water content of at least 70% is used. The substrate to be printed is supported by a workpiece support and is moved relative to the inkjet printing device. During this relative movement, ink is applied by the inkjet printing device to the surface of the substrate to be printed. The ink that is applied to the surface of the substrate is heated to a temperature that is above the temperature of the air surrounding the substrate and that is below the boiling point of the solvent contained in the ink. Above a liquid phase of the ink, a vapor layer, consisting of the solvent that is contained in the ink, is formed. The vapor layer that is formed above the liquid phase of the ink is transported away by an air flow emitted by at least one blower nozzle unit. The air output by the respective blower nozzle unit is heated or is dehumidified beforehand. A digital printing press is provided for carrying out this method.

A transport device includes a transporting belt, which includes a support face that adhesively supports a medium, and which transports the adhered medium, a heating unit that heats the transporting belt before the medium is supported at the support face, a pressing unit that is provided downstream of the heating unit in a movement direction of the transporting belt and that presses the medium against the support face, a temperature detection unit that detects a temperature of at least a part of the support face, from the heating unit to the pressing unit in the movement direction, and a control unit that controls the heating unit based on a detection result of the temperature detection unit.

An image formation apparatus includes: a sheet feeder that conveys a paper fed from a sheet feed tray; a conveyance cylinder that includes a gripper that grips the paper, and receives the paper conveyed on the sheet feeder and conveys the paper to a position of a printing part in a state where the paper is gripped by the gripper; and a heater that is provided on an upstream side of the conveyance cylinder in a conveyance direction and heats the paper so as to satisfy a temperature condition of following Expression (1):

|T1−T2|/T1<0.15   Expression (1)

where T1 is a temperature [° C.] of a paper end of the paper at the position of the printing part, and T2 is a temperature [° C.] of the paper end of the paper when the paper is transferred from the sheet feeder to the conveyance cylinder.

A liquid ejecting system includes an environmental information acquiring unit that acquires, as environmental information at least one of a temperature and a humidity, an ejecting unit that ejects a liquid onto a medium, a drying unit that dries the medium onto which the liquid is ejected by the ejecting unit, a control unit that controls the ejecting unit and the drying unit, and a storage unit that stores setting information. The control unit acquires drying information corresponding to medium type information and ejection amount information acquired as a liquid ejection condition and the environmental information acquired by the environmental information acquiring unit, based on the setting information stored in the storage unit, and performs drying control that controls the drying unit, based on the acquired drying information.

The anti-drop members 7l and 7r are provided to each of the air turn bars 6u and 6l, and the respective anti-drop peripheral surfaces 711 of the anti-drop members 7l and 7r adjoin the support peripheral surface 611 of each of the air turn bars 6u and 6l. In this configuration, on the occurrence of oblique traveling of the printing medium M, the printing medium M is deviated from the support peripheral surface 611 of each of the air turn bars 6u and 6l to the anti-drop peripheral surface 711 of the anti-drop member 7l or 7r. Specifically, the anti-drop peripheral surface 711 of each of the anti-drop members 7l and 7r allows the printing medium M to be supported while providing the clearance Δ from the front surface M1 of the printing medium M deviated by the oblique traveling.

A holding portion is held by a main body portion. The holding portion includes at least one recording head, a carriage, a cover portion, and a blowing unit. The recording head is capable of discharging ink. The carriage has a bottom wall portion to which at least one recording head is attached, and accommodates the at least one recording head. A cover portion has a facing surface facing the bottom wall portion. The blowing unit blows an air toward the facing surface so that the air reaches the recording head.

A drying device includes a support unit, a heating unit, and a control unit. The heating unit includes a duct, which has a blowing outlet, a suction inlet, and an air port and includes an air flow path, a heating section, a blower, and a first adjustment unit capable of adjusting an amount of air flowing into the air flow path from an outside of the duct through the air port. The control unit is capable of executing a first mode in which the first adjustment unit is controlled to adjust the amount of air in a state in which the heating section performs heating and a second mode in which the first adjustment unit is controlled to cause the amount of air to be more than the amount of air in the first mode in a state in which heating by the heating section is stopped.

A printing apparatus includes a conveyance unit configured to convey a print medium, a printhead for printing an image by discharging ink to the conveyed print medium, a heating unit provided on a downstream side of the printhead with respect to a conveyance direction of the print medium and configured to heat the print medium, and a ventilation unit provided on a downstream side of the heating unit with respect to the conveyance direction and configured to ventilate air in a peripheral space of a conveyance path of the print medium. The printing apparatus controls to delay a start of printing by the printhead so that the print medium dried by the heating unit passes through the conveyance path in a state in which a humidity in the space becomes lower than a predetermined value due to the ventilation.
