Abstract: A flexible flat cable connects a drive circuit and a liquid jetting head to supply a drive signal to pressure generating elements. The flat cable includes a plurality of laminated layers, each provided with a plurality of first conductive patterns each connecting a positive pole of the drive circuit and a positive pole of one of the pressure generating elements, and a plurality of second conductive patterns each connecting a negative pole of the drive circuit and a negative pole of one of the pressure generating elements. Each of at least one of the first conductive patterns provided in one of the laminated layers faces one of the first conductive patterns provided in adjacent one of the laminated layers. Each of at least one of the second conductive patterns provided in one of the laminated layers faces one of the second conductive patterns provided in adjacent one of the laminated layers.

Abstract: A recording head provided with a plurality of nozzles, a plurality of pressure chambers, each communicated with one nozzle, and a plurality of pressure generating elements, each associated with one pressure chamber and actuated to eject ink from one associated nozzle. An ejection controller specifies a nozzle from which an ink droplet having the least weight is ejected as a reference nozzle. A driving signal generator generates a driving signal applied to the respective pressure generating elements. The drive signal has a driving voltage determined such that an ink droplet ejected from the reference nozzle has a predetermined flight velocity or more.
