A printing apparatus includes a conveyance unit configured to convey a sheet, a printing unit configured to print an image by discharging ink to the sheet conveyed by the conveyance unit, a heating unit configured to heat the sheet conveyed by the conveyance unit and to which the image has been printed by the printing unit, and a control unit configured to, in a case of double-side printing in which after printing an image on a first side of the sheet, an image is printed on a second side of the sheet, based on an amount of ink discharged for the first side and an amount of ink discharged for the second side, control heating by the heating unit with respect to the second side.

Printing apparatus and method for controlling the same

A printing apparatus includes a conveyance unit configured to convey a sheet along a conveyance path, a printing unit configured to print an image by discharging ink to the sheet conveyed by the conveyance unit, a heating unit configured to, in a heating section on the conveyance path, heat the sheet on which the image has been printed by the printing unit, and a control unit configured to control the heating unit so that the heating section is changed in accordance with a print condition.

Printing apparatus and control method controlling heating of medium

A liquid discharge apparatus includes a conveying part configured to convey a medium in a conveying direction. A discharge head is configured to discharge a droplet onto a medium carried by the conveying part. A heating part is arranged at the downstream of the discharge head and configured to heat a medium while contacting with the medium attached with a droplet discharged by the discharge head. The heating part is arranged at a position contacting with at least part of the droplet present on the surface of the medium.

Liquid discharge apparatus

A printing apparatus includes a conveyance unit, a printing unit, and a heating unit provided on a downstream side with respect to the printing unit in the conveyance direction, and a control unit. The conveyance unit conveys a printing medium along a conveyance direction. The printing unit ejects ink onto the printing medium conveyed by the conveyance unit. The heating unit heats the printing medium on which ink has been ejected by the printing unit while being in contact therewith. The control unit controls the printing apparatus such that a first surface of the printing medium passes through the same heating unit a plurality of times, wherein the first surface includes ink having been ejected by the printing unit onto the first surface.

Printing apparatus and control method

Printing apparatus and method for controlling heating of sheet based on discharged ink amount

A printing apparatus includes a conveyance unit configured to convey a print medium, a printhead configured to print an image by discharging ink to the print medium conveyed by the conveyance unit, a heating unit provided downstream of the printhead with respect to a conveyance direction of the print medium and configured to heat the print medium on which the image is printed by the printhead, and a correction unit provided downstream of the heating unit with respect to the conveyance direction and configured to correct curl occurring in the print medium. The apparatus controls to delay, between the heating unit and the correction unit, the conveyance of the print medium heated by the heating unit.

Printing apparatus and control method therefor

An inkjet printing apparatus according to the present invention includes a first printing head that performs a first printing operation by discharging ink onto the printing medium, a second printing head positioned downstream from the first printing head in a transport direction and performing a second printing operation by discharging ink onto the printing medium, and a preliminary discharge controller that causes the second printing head to perform a preliminary discharging operation that does not contribute to the second printing operation, wherein the preliminary discharge controller causes an ink discharge amount of the preliminary discharging operation of the second printing head to be smaller when an ink discharge amount of the first printing operation is greater than or equal to a predetermined value than when the ink discharge amount of the first printing operation is less than the predetermined value.
