Abstract
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).
Claims8
A liquid discharge apparatus comprising:
- 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, wherein
- when the humidity detection unit detects a humidity less than a first predetermined value, the interior of the housing is humidified by the humidifying unit during transport by the transport unit or during discharge by the discharge unit, wherein
- when a transport amount of the medium transported by the transport unit is not less than a second predetermined value until a job executed by the discharge unit and the transport unit is completed after the humidity detection unit detects a humidity less than the first predetermined value, the interior of the housing is humidified by the humidifying unit, and
- when the transport amount is less than the second predetermined value, humidification is not performed.
A liquid discharge apparatus comprising:
- a transport unit configured to transport a medium;
- a discharge unit configured to discharge a liquid onto the medium;
- a support portion configured to support a portion of the medium, the liquid being discharged from the discharge unit onto the portion of the medium;
- a housing including therein the discharge unit;
- a heating unit configured to heat the medium onto which the liquid is discharged from the discharge unit;
- and
- a humidity detection unit configured to detect a humidity, wherein
- when the humidity detection unit detects a humidity exceeding a first predetermined value and when a liquid amount per unit area of the liquid discharged from the discharge unit is less than a second predetermined value, the temperature of the heating unit is lowered during transport by the transport unit or during discharge by the discharge unit, wherein
- when a transport amount of the medium transported by the transport unit is not less than a second predetermined value until a job executed by the discharge unit and the transport unit is completed after the humidity detection unit detects a humidity less than the first predetermined value, the interior of the housing is humidified by the humidifying unit, and
- when the transport amount is less than the second predetermined value, humidification is not performed.
A method for controlling a liquid discharge apparatus including 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,
- the method comprising:
- a humidity detection step for detecting a humidity;
- and
- a humidification step for humidifying the interior of the housing by the humidifying unit:
- when the humidity detection unit detects a humidity less than a first predetermined value during transport by the transport unit or during discharge by the discharge unit, and
- when a transport amount of the medium transported by the transport unit is not less than a second predetermined value until a job executed by the discharge unit and the transport unit is completed after the humidity detection unit detects a humidity less than the first predetermined value, and
- when the transport amount is less than the second predetermined value, humidification is not performed.
A method for controlling a liquid discharge apparatus including 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 heating unit configured to heat the medium onto which the liquid is discharged from the discharge unit, and a humidity detection unit configured to detect a humidity,
- the method comprising:
- a first determination step for determining whether the humidity detection unit detects a humidity exceeding a first predetermined value;
- a second determination step for determining whether a liquid amount per unit area of the liquid discharged from the discharge unit is less than a second predetermined value;
- a heating control step for, when the humidity detection unit detects a humidity exceeding the first predetermined value and when the liquid amount per unit area of the liquid discharged from the discharge unit is less than the fifth predetermined value, lowering a temperature of the heating unit during transport by the transport unit or during discharge by the discharge unit;
- and
- a humidification step for humidifying the interior of the housing by the humidifying unit
- when the humidity detection unit detects the humidity less than a first predetermined value during transport by the transport unit or during discharge by the discharge unit, and
- when a transport amount of the medium transported by the transport unit is not less than a second predetermined value until a job executed by the discharge unit and the transport unit is completed after the humidity detection unit detects a humidity less than the first predetermined value, and
- when the transport amount is less than the second predetermined value, humidification is not performed.
