Abstract:
An inkjet print head includes a droplet ejection unit having a pressure chamber; a first actuator configured for changing a volume of the pressure chamber; a second actuator configured for changing the volume of the pressure chamber; and a nozzle orifice. The inkjet print head further includes a control circuitry operatively connected to the first actuator and the second actuator. The control circuitry includes a drive circuitry for supplying a drive signal to at least one of the first and the second actuator; a sensing circuitry for receiving a sense signal from the first actuator; and a switch circuitry for switching a connection of the first actuator between a connection to the drive circuitry and a connection to the sensing circuitry.

Claim (Index 3):
The method according to  claim 1 , further comprising, prior to selecting the drive mode:\n applying a predetermined analysis drive signal to at least one of the first actuator and the second actuator; receiving the sense signal from the first actuator; and analyzing the sense signal for determining at least one acoustic property of a group of properties of the pressure chamber and a liquid present in the pressure chamber, the group of acoustic properties comprising the liquid viscosity, the liquid density, an actuator efficiency, and a presence of acoustic disturbances.
