Abstract
In accordance with an embodiment, an inkjet head comprises a head section, a clock signal generator, a drive controller and a current measurement section. The head section applies a drive voltage to a wall surface of an ink chamber and ejects ink from the ink chamber. The clock signal generatorsends a clock signal to the head section. The drive controller stops the clock signal sent to the head section, and applies a predetermined drive voltage to the head section. The current measurement section measures a current flowing to the head section while the drive controller stops the clock signal sent to the head section.
Claims20
An inkjet head, comprising:
- a head section configured to apply a drive voltage to a wall surface of an ink chamber and eject ink from the ink chamber;
- a clock signal generator configured to send a clock signal to the head section;
- a drive controller configured to stop the clock signal sent to the head section, and apply a predetermined drive voltage to the head section;
- and
- a current measurement section configured to measure a current flowing to the head section while the drive controller stops the clock signal sent to the head section.
