Claims9
An inkjet printing apparatus comprising:
- a print head configured to perform printing by ejecting an ink from an ejection port;
- an ink receiving unit configured to receive an ink ejected from the print head;
- a control unit configured to cause the print head to perform ejection operation to the ink receiving unit;
- and
- an obtaining unit configured to obtain information relating to a condensation degree of ink, wherein
- the control unit causes the print head to perform the ejection operation based on the information relating to a condensation degree of ink obtained by the obtaining unit.
A recovery processing method of an inkjet printing apparatus including a print head configured to perform printing by ejecting an ink from an ejection port and an ink receiving unit configured to receive an ink ejected from the print head, the method comprising:
- an ejecting step of ejecting an ink from the ejection port;
- an obtaining step of obtaining information relating to a condensation degree of ink;
- and
- a recovering step of causing the print head to perform ejection operation to the ink receiving unit based on the information relating to a condensation degree of ink obtained in the obtaining step.
