Abstract
A printing apparatus includes: a control unit configured to control a first heating process and a second heating process and configured to control the first heating process and the second heating process to be performed before a printing head starts printing an image on printing medium that is a printing target, wherein the second heating process is performed after the first heating process and before the printing head prints the image, and wherein a first target temperature in the first heating process is higher than a second target temperature in the second heating process.
Claims17
A printing apparatus comprising:
- a printing head configured to print an image by ejecting ink to a printing medium that has been conveyed;
- a heating unit configured to heat the printing head;
- and
- a control unit configured to control performance of a selected one of (1) a first heating process and (2) the first heating process and a second heating process, each of the first heating process and the second heating process being a process, performed before the printing head starts printing the image on the printing medium that is a printing target, in which the heating unit is made to perform heating so that a temperature of the printing head becomes a target temperature,
- wherein a first target temperature, which is the target temperature in the first heating process, is higher than a second target temperature, which is the target temperature in the second heating process,
- wherein in a case where the temperature of the printing head is lower than the second target temperature at a predetermined timing after the first heating process, the control unit performs the second heating process and then the printing head prints the image, and
- wherein in a case where the temperature of the printing head is not lower than the second target temperature at the predetermined timing after the first heating process, the control unit does not perform the second heating process and then the printing head prints the image.
A control method of a printing apparatus, the printing apparatus including (1) a printing head configured to print an image by ejecting ink to a printing medium that has been conveyed and (2) a heating unit configured to heat the printing head, the control method comprising:
- performing a selected one of (1) a first heating process and (2) the first heating process and a second heating process, each of the first heating process and the second heating process being a process in which the heating unit is made to perform heating so that a temperature of the printing head becomes a target temperature,
- wherein a first target temperature, which is the target temperature in the first heating process, is higher than a second target temperature, which is the target temperature in the second heating process,
- wherein in a case where the temperature of the printing head is lower than the second target temperature at a predetermined timing after the first heating process, the second heating process is performed in the performing and then the printing head prints the image, and
- wherein in a case where the temperature of the printing head is not lower than the second target temperature at the predetermined timing after the first heating process, the second heating process is not performed in the performing and then the printing head prints the image.
A non-transitory computer-readable storage medium storing a program which causes a computer to perform a control method of a printing apparatus, the printing apparatus comprising (1) a printing head configured to print an image by ejecting ink to a printing medium that has been conveyed and (2) a heating unit configured to heat the printing head, the control method comprising:
- performing a selected one of (1) a first heating process and (2) the first heating process and a second heating process, each of the first heating process and the second heating process being a process in which the heating unit is made to perform heating so that a temperature of the printing head becomes a target temperature,
- wherein a first target temperature, which is the target temperature in the first heating process, is higher than a second target temperature, which is the target temperature in the second heating process,
- wherein in a case where the temperature of the printing head is lower than the second target temperature at a predetermined timing after the first heating process, the second heating process is performed in the performing and then the printing head prints the image, and
- wherein in a case where the temperature of the printing head is not lower than the second target temperature at the predetermined timing after the first heating process, the second heating process is not performed in the performing and then the printing head prints the image.
