ABSTRACT:
A recovery device for an ink jet printer is disclosed that is used to perform discharge recovery on an ink jet recording head when the discharge port of the recording head is blocked. The recovery device of the present invention includes a pressing member that is used during the discharge recovery procedure to press on an ink chamber contained within the recording head. The pressure being applied to the ink chamber causes the ink within the chamber to be discharged from the discharge port of the recording head. The pressing member can be moved between (i) a recovery position wherein it extends from a receiving surface of the recovery device in an orientation such that it can be used to press against the ink chamber during a discharge recovery operation and (ii) a retracted position wherein it is received by the receiving surface when not performing the discharge recovery operation.
