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.
Claims17
An inkjet recording apparatus comprising:
- a recording head including a row of discharge ports including a plurality of discharge ports configured to discharge ink, and a storage section configured to store ink to be discharged from the row of discharge ports;
- an obtaining unit configured to obtain an amount of ink in the storage section;
- a recovery unit configured to recover the recording head;
- a prediction unit configured to predict, based on an input recording job, a volume of air bubbles generated in the storage section;
- and
- a controller configured to perform control to cause the recovery unit to perform a recovery operation when the volume of the amount of ink is less than the volume of air bubbles.

An inkjet recording apparatus comprising:
- a recording head including a first row of discharge ports, a second row of discharge ports, a first storage section, and a second storage section, the first and second rows of discharge ports including a plurality of discharge ports configured to discharge ink, the first storage section configured to store ink to be discharged from the first row of discharge ports, and the second storage section configured to store ink to be discharged from the second row of discharge ports;
- an obtaining unit configured to obtain an amount of ink in each of the first and second storage sections;
- a recovery unit configured to recover the recording head;
- a prediction unit configured to predict, based on an input recording job, a volume of air bubbles generated in each of the first and second storage sections;
- and
- a controller configured to perform control to cause the recovery unit to perform a recovery operation when the volume of the amount of ink, which is a smaller one of the amounts of ink obtained by the obtaining unit, is less than the volume of air bubbles.
