Abstract
There is provided with a printing apparatus. A printing unit prints an image on a print medium. A heating unit heats the print medium with the image printed thereon. A detection unit detects a temperature of the heating unit. A housing accommodates the printing unit and the heating unit. An openable/closable cover member is provided on the housing and covers the heating unit. A restricting unit is capable of restricting an opening operation of the cover member. A control unit controls the restricting unit so as to execute the restriction if the temperature of the heating unit exceeds a first threshold value, and release the restriction if the temperature of the heating unit is not more than a second threshold value lower than the first threshold value.
Claims19
A printing apparatus comprising:
- a printing unit configured to print an image on a print medium;
- a heating unit configured to heat the print medium with the image printed thereon;
- a detection unit configured to detect a temperature of the heating unit;
- a housing configured to accommodate the heating unit;
- a cover member provided on the housing and configured to be capable of being opened and closed, with the cover member covering the heating unit in a closed state;
- a restricting unit capable of restricting an opening operation of the cover member;
- and
- a control unit configured to control the restricting unit so as to execute the restriction if the temperature of the heating unit rises to a temperature that exceeds a first threshold value, with the control unit not releasing the restriction until the temperature of the heating unit falls from the first threshold value to a second threshold value that is lower than the first threshold value, and with the control unit releasing the restriction if the temperature of the heating unit is not more than the second threshold value.
A control method of a printing apparatus including:
- a printing unit configured to print an image on a print medium;
- a heating unit configured to heat the print medium with the image printed thereon;
- a housing configured to accommodate the heating unit;
- a cover member provided on the housing and configured to be capable of being opened and closed, with the cover member covering the heating unit in a closed state;
- and
- a restricting unit capable of restricting an opening operation of the cover member,
- the method comprising:
- detecting a temperature of the heating unit;
- and
- controlling the restricting unit so as to execute the restriction if the temperature of the heating unit rises to a temperature that exceeds a first threshold value, with the restriction not being released until the temperature of the heating unit falls from the first threshold value to a second threshold value that is lower than the first threshold value, and with the restriction being released if the temperature of the heating unit is not more than a second threshold value.
A printing apparatus comprising:
- a printing unit configured to print an image on a print medium by discharging liquid to the print medium through a nozzle;
- a conveyance unit to convey the print medium in a direction;
- a heating unit configured to heat the print medium with the image printed thereon, the heating unit being arranged downstream of the printing unit in the direction;
- a detection unit configured to detect a temperature of the heating unit;
- a housing configured to accommodate the printing unit and the heating unit;
- a cover member provided on the housing and configured to be capable of being opened and closed, with the cover member covering the heating unit in a closed state;
- a restricting unit capable of restricting an opening operation of the cover member;
- and
- a control unit configured to control the restricting unit so as to execute the restriction if the temperature of the heating unit exceeds a first threshold value, and release the restriction if the temperature of the heating unit is not more than a second threshold value that is lower than the first threshold value.
