摘要： The present inventions allow the detection of ink in the printing head by significantly simplified their configurations and on which various printing systems can be widely applied. There are a heater (101) for supplying an energy to ejecting ink, a driver (102) for driving heater (101), and a detection electrode (118) capable of detecting a voltage variation between the heater (101) and the driver (102) to be occurred depending on the driving of the heater (101). Furthermore, an insulating film (410) that covers the surface of the detection electrode (118) prevents a chemical or physical change from the detection electrode (118). Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element (101) and another signal source (101) improve the accuracy of ink-detection. A drive pulse which is insufficient to ejecting ink may be supplied to the heater (101) to improve the accuracy of ink-detection.
