Ink jet recording apparatus provided with means for calculating waste ink amount, and information processing system provided with such an ink jet recording apparatus

摘要

In an ink jet recovery apparatus, a recovery operation of the recording head is performed by exhausting ink from the recording head. The recording apparatus has a waste ink storage tank to store the ink exhausted in the recovery operation. The amount of waste ink currently stored in the waste ink storage tank is calculated in accordance with the amount of ink exhausted up to the present, the elapsed time since the last recovery operation, and the amount of ink exhausted in the current recovery operation. The amount of ink stored in the waste ink storage tank can thus be accurately monitored, so that waste ink is not allowed to flow out of the storage tank. Users can be informed of overflow of the waste ink and thereby prompted to exchange the tank; space required for the tank can thus be reduced.
