ABSTRACT:
An inkjet head has a flow path unit having a first surface and a second surface opposite the first surface. The flow path unit ejects ink in an ink ejection direction. The flow path unit has wall plates positioned on the second surface, extending away from the flow path unit. The inkjet head has a cover contacting at least one of the wall plates. The cover covers a portion of the second surface, and the cover has sidewalls. A first portion of at least one of the sidewalls contacts a first portion of corresponding wall plates, and a second portion of at least one of the sidewalls and a second portion of the corresponding wall plates defines a gap between them. The inkjet head has a seal positioned in the gap, and the seal prevents fluid from entering the gap.
