Recording head recovery mechanism, inkjet recording apparatus, and recording head recovery method

摘要

A recovery mechanism for a recording head includes a wiper and a drive mechanism. The recovery mechanism performs a residual ink attachment operation of attaching residual ink from a tip of the wiper at a first position. After the residual ink attachment operation, the recovery mechanism performs an ink wiping operation of wiping away the residual ink and purged ink by moving the wiper along an ink discharge surface toward the first position from a second position at an opposite side of a nozzle region relative to the first position.

主权项

1. A recovery mechanism for a recording head having a nozzle region in which an opening of a discharge nozzle for discharging ink onto a recording medium is present, the recovery mechanism comprising:
a wiper configured to wipe away ink purged from the discharge nozzle; a drive mechanism configured to cause raising and lowering movement of the wiper and to cause forward and backward movement of the wiper along an ink discharge surface that includes the nozzle region; and a control section configured to perform
a residual ink attachment operation of attaching residual ink from a tip of the wiper onto the ink discharge surface at a first position outside of the nozzle region by controlling the drive mechanism to press the wiper against the ink discharge surface at the first position and subsequently controlling the drive mechanism to move the wiper along the ink discharge surface,an ink purging operation of purging ink from the discharge nozzle such that purged ink is attached to the nozzle region, andan ink wiping operation of after the residual ink attachment operation, wiping away the purged ink and the residual ink by controlling the drive mechanism to move the wiper along the ink discharge surface toward the first position from a second position at an opposite side of the nozzle region relative to the first position.
