Abstract
A maintenance apparatus of a recording head is appressed against a head main body of a recording head during cleaning processing, and an air current which performs suction and removal flows in a direction crossing an ink discharge direction and travels along a nozzle surface to suck foreign particles or a residual ink.
Claims19
A maintenance apparatus of a recording head which is applied to an inkjet recording head having a nozzle plate on which many nozzles which discharge an ink are linearly arranged, comprising:
- a sucking portion which is provided to face the nozzle plate and exerts a suction force with respect to at least one of the nozzles and the nozzle plate,
- wherein the sucking portion exerts the suction force with respect to at least one of the nozzles and the nozzle plate in a direction crossing a discharge direction of the ink discharged from the nozzles.
A maintenance apparatus of a recording head which is applied to an inkjet recording head having a nozzle plate on which many nozzles which discharge an ink are linearly arranged, comprising:
- a sucking portion which is provided to face the nozzle plate and exerts a suction force with respect to at least one of the nozzles and the nozzle plate,
- wherein the sucking portion is provided in such a manner that an air intake portion and sucking openings which exert a suction force with respect to at least one of the nozzles and the nozzle plate face each other with the linearly arranged nozzles therebetween.
A maintenance apparatus of a recording head, having:
- a recording head which has a plurality of linearly arranged nozzles and a nozzle plate on which the nozzles are formed;
- a sucking portion which covers some of the plurality of nozzles of the recording head and generates an air current which sucks an ink;
- and
- a scanning mechanism which moves the sucking portion along an arrangement direction of the nozzles,
- wherein the sucking portion generates the air current in such a manner that the air current flows in a direction orthogonal to an ink discharge direction and a direction crossing the nozzle arrangement direction at a position facing the nozzles.
