Inkjet recording apparatus
An inkjet recording apparatus includes a head unit, a wipe unit, and a control part. The head unit is provided with a nozzle surface on which a plurality of ink ejection ports is opened downward. The wipe unit performs a wiping operation in which a blade is moved along the nozzle surface while applying a cleaning liquid to the nozzle surface to wipe the nozzle surface. The control part controls the head unit and the wipe unit to perform a first maintenance operation to perform the wiping operation and a second maintenance operation to perform the wiping operation after the ink is pushed out from the nozzle surface. In the second maintenance operation, the cleaning liquid applied to the nozzle surface is suppled firstly, then the ink is pushed out from the nozzle surface, and then wiping operation is performed.
1 . An inkjet recording apparatus comprising:
a head unit provided with a nozzle surface on which a plurality of ink ejection ports is opened downward and movable to a retracted position and a cleaning position;
a wipe unit which includes a blade movable from a moving start position to a moving end position and a cleaning liquid supply member which supplies a cleaning liquid to be applied to the nozzle surface to the blade at the moving start position, and is movable to a standby position and a wiping position; and
a control part which controls the head unit and the wipe unit to perform a first maintenance operation to move the wipe unit to the wiping position, then to move the recording head to the cleaning position, and then to perform a wiping operation in which the blade is moved from the moving start position to the moving end position along the nozzle surface while applying the cleaning liquid supplied from the cleaning liquid supply member to the nozzle surface to wipe the nozzle surface, and a second maintenance operation to perform the wiping operation after the ink is pushed out from the nozzle surface, wherein
the control part performs the second maintenance operation such that the cleaning liquid applied to the nozzle surface is suppled from the cleaning liquid supply member, then the wipe unit is moved to the wiping position, then the recording head is moved to the cleaning position, then the ink is pushed out from the nozzle surface, and then the wiping operation is performed.
2 . The inkjet recording apparatus according to claim 1 , wherein
when the wipe unit is moved to the wiping position, the cleaning liquid supply member is moved to a cleaning liquid supply position, and when the wipe unit is moved to the standby position, the cleaning liquid supply member is separated from the cleaning liquid supply position and the cleaning liquid can be supplied to the cleaning liquid supply member.
3 . The inkjet recording apparatus according to claim 1 , wherein
the wipe unit includes a waste liquid tray in which the ink wiped off by the wiping operation falls.
4 . The inkjet recording apparatus according to claim 1 , wherein
a first moving speed of the blade at the first maintenance operation is slower than a second moving speed of the blade at the second maintenance operation.
