Abstract
An inkjet recording apparatus predicts the volume of air bubbles generated in a storage section of a recording head based on an input recording job. When the volume of the amount of ink in the storage section of the recording head is less than the predicted volume of air bubbles, a recovery operation is performed.
Claims6
