ABSTRACT:
An inkjet head may include a main-body block, which may include a reservoir configured to store ink, an ink supply port configured to supply the ink to the reservoir, and a plurality of nozzles in fluid communication with the reservoir via an ink flow path. The inkjet head may include a supply valve mechanism attached to the main-body block and configured to selectively set the ink supply port in one of a sealed state and an open state. The inkjet head may further include an attachment unit configured to be removably attached to the main-body block. The attachment unit may include a supply channel configured to supply the ink to the ink supply port. The supply valve mechanism may set the ink supply port in the sealed state when the attachment unit is detached from the main-body block, and set the ink supply port in the open state when the attachment unit is attached to the main-body block.
