Fluid jetting device comprising: a nozzle plate, a fluid chamber terminating in an orifice in the nozzle plate, an actuator for generating a pressure wave in a fluid in the fluid chamber to jet fluid through the orifice from the chamber, a jetting waveform generating device connected to the actuator for generating an excitation waveform comprising two separated pulses, called a jetting pulse and a quenching pulse, for respectively generating a pressure wave in the fluid in the fluid chamber leading to a fluid droplet and for substantially cancelling a pressure wave in the fluid in the fluid chamber, wherein the jetting waveform generating device is adapted to make, when jetting two consecutive fluid droplets, a first and a second droplet, the jetting pulse of the second droplet at least partially overlap the quenching pulse directly following the jetting pulse of the first droplet.

Fluid jetting device, printing apparatus, and method therefor

An image transfer system comprising an endless belt serving as an image carrier and passing through a first processing station where it is maintained at a low temperature and through a second processing station where it is maintained at a higher temperature, and a heat exchanger formed by two portions of said belt moving in opposite directions and held in sliding contact with each other by a pressing member, the pressing member being a deflecting roller that co-rotates with the belt portion that is directly in contact therewith.
