Abstract
The maintenance device includes a cap and a suppression member. The cap, including an air supply port and an air discharge port, is to be fitted to a nozzle surface of an inkjet head. The suppression member is opposed to the air supply port, provided between the air supply port and the nozzle surface, and separate from the air supply port and also separate from the nozzle surface.
Claims17
A maintenance device comprising:
- a cap which includes an air supply port and an air discharge port, and which is to be fitted to a nozzle surface of an inkjet head;
- and
- a suppression member which is opposed to the air supply port, and which is provided between the air supply port and the nozzle surface, and moreover which is separate from the air supply port and also separate from the nozzle surface,
- wherein
- wetted air flows through the air supply port into the cap,
- the suppression member is provided above the air supply port so as to cover the whole air supply port, as viewed in a plan view and suppresses generation of condensations on the nozzle surface,
- the suppression member includes a plurality of through holes which are placed so as not to be opposed to the air supply port, and which are bored through from the air supply port side to the nozzle surface side, and
- the through holes become larger in diameter with increasing nearness to the air discharge port.
