Abstract

A method of maintaining an inkjet print head device (10) includes applying a first set of maintenance signals by a control unit (15) to a first set of actuators (11a) of an inkjet print head device. The first set of maintenance signals applied by the control unit causes movement of the first set of actuators to move meniscuses of a first set of fluid channels (12a) in fluid communication with the first set of actuators, respectively, between an expansion state and a retraction state without fluid droplets ejecting from the first set of fluid channels. The method also includes applying a second set of maintenance signals by the control unit to the first set of actuators of the inkjet print head device. The second set of maintenance signals applied by the control unit cause movement thereof to circulate fluid in the first set of fluid channels without the fluid droplets ejecting from the first set of fluid channels.
