Inkjet recording apparatus

摘要

An inkjet recording apparatus comprises an inkjet recording head (2), an ink-testing unit (3a) having an ink-test chamber (52), a pressure-vibration generating unit (45a) that generates a pressure vibration in the ink-test chamber, a pressure-vibration detecting unit (45b) that detects the pressure vibration, an ink inlet (41) that introduces ink into the ink-test chamber (52) and an ink outlet (42) through which ink is discharged from the ink-test chamber (52). Failures of ink ejection can be prevented by detecting cavitation cores by the ink-test chamber and removing ink containing the cavitation cores from ink supplied to the inkjet recording head.
