Abstract
The present invention relates to a discharge recovery processing of an ink jet recording apparatus which forms an image on the recording medium by discharging the ink. The invention aims to prevent the increase in the running costs and the shortened life of a waste ink tank by preventing the wasteful ink consumption which may be caused by the dual use of an automatic recovery processing and a manual recovery processing after the replacement of an ink tank. Also, the invention further aims to provide an ink jet recording apparatus with high safety and reliability as well as effecting an appropriate recovery by controlling the movement of head in involving the recovery.
