Abstract:
A connection cable electrically connects a head unit and a head unit control circuit. The head unit includes: an ejector, a determination circuit, and an ejection limit circuit. The ejector includes a displaceable piezoelectric element for controlling the liquid ejection. The piezoelectric element is displaced by changing a drive signal potential. The determination circuit determines whether the piezoelectric element has a predetermined electrical storage capability. The ejection limit circuit stops the drive signal to limit the ejection of the liquid based on the determination. The connection cable includes: a first connection supplying a determination instruction signal from the head unit control circuit to the head unit; a second connection supplying the drive signal from the head unit control circuit to the head unit; and a third connection between the first and second connections with a smaller potential change width than the second connection when the ejector ejects the liquid.

Claim (Index 7):
The connection cable as defined in  claim 5 ,\n the head unit control circuit generating a first designation signal, a second designation signal, and a third designation signal, the first designation signal designating whether or not to cause the ejecting section to eject the liquid when the result of the diagnosis differs from the predetermined result and the liquid can be ejected from the ejecting section, the second designation signal defining a period in which the liquid is ejected from the ejecting section when the result of the diagnosis differs from the predetermined result and the liquid can be ejected from the ejecting section, the third designation signal being set to a low level so that a switch provided between the second connection line and the piezoelectric element is turned ON when the result of the diagnosis differs from the predetermined result and the liquid can be ejected from the ejecting section, and the diagnosis circuit executing the diagnosis during a diagnosis period in which the first designation signal is set to a high level, the second designation signal is set to a high level, and the third designation signal is set to the low level, and the diagnosis circuit stopping the supply of the drive signal to the piezoelectric element and limiting the ejection of the liquid from the ejecting section when the result of the diagnosis is the predetermined result and the diagnosis period ends.
