Printing apparatus
A printing apparatus includes: a tank configured to contain ink; a print head configured to eject ink supplied from the tank; a supply flow path through which liquid is supplied from the tank to the print head; a collection flow path through which liquid is collected from the print head to the tank; a circulation unit configured to circulate ink inside a circulation flow path including the tank, the supply flow path, the print head, and the collection flow path; and a cooling unit configured to cool the tank by blowing.
1. A printing apparatus comprising:
a tank configured to contain liquid to be supplied to a print head which ejects liquid;
a supply flow path through which liquid is suppled from the tank to the print head;
a collection flow path through which liquid is collected from the print head to the tank;
a circulation unit configured to circulate liquid inside a circulation flow path including the tank, the supply flow path, the print head, and the collection flow path;
a first cover configured to cover the tank, the first cover being formed with a first opening;
a fan configured to suck air from the first opening, wherein the tank faces the first opening; and
a maintenance unit configured to perform maintenance operation for the print head, wherein the fan is included in the maintenance unit.
2. The printing apparatus according to claim 1 , wherein the maintenance unit is arranged below the tank in a gravitational direction.
3. The printing apparatus according to claim 1 , wherein
the print head is located at one side of the tank opposite from the first opening.
4. The printing apparatus according to claim 1 , wherein
in a state where the fan is driven, air supplied from the first opening flows through the tank, the print head, and the maintenance unit, in sequence.
5. The printing apparatus according to claim 1 , wherein
the print head includes
a control board configured to control ejection from the print head.
6. The printing apparatus according to claim 1 , wherein
the print head includes an ejection opening surface on which ejection openings are arranged, and
wherein the print head is capable of moving to a first position where the ejection opening surface is facing downward in the gravitational direction and a second position where the ejection opening surface is inclined with respect to a horizontal direction.
7. The printing apparatus according to claim 1 , further comprising a power supply unit above the tank.
8. The printing apparatus according to claim 1 , wherein, in a state where the fan is driven, air supplied from the first opening flows through the tank and the print head.
9. The printing apparatus according to claim 1 , wherein, in a state where the fan is driven, air supplied from the first opening flows through the circulation flow path.
10. The printing apparatus according to claim 1 , further comprising
a second cover configured to cover the maintenance unit, the second cover being formed with a second opening, and
wherein in a state where the fan is driven, air is supplied from the first opening toward the second opening.
