Abstract
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.
Claims24
A printing apparatus comprising:
- 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;
- 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;
- and
- a control unit configured to control a conveyance speed of the conveyance unit so as to convey the print medium at a first speed between the printhead and the heating unit and to convey the print medium at a second speed slower than the first speed between the heating unit and the correction unit.
A control method for a printing apparatus including 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 method comprising:
- controlling a conveyance speed of the conveyance unit so as to convey the print medium at a first speed between the printhead and the heating unit and to convey the print medium at a second speed slower than the first speed between the heating unit and the correction unit.
A printing apparatus comprising:
- 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;
- 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;
- and
- a control unit configured to control to stop temporarily the conveyance of the print medium, which has been heated by the heating unit and is conveyed between the heating unit and the correction unit, so as to delay a timing at which the print medium enters the correction unit.
