Abstract: In a printer configured to perform two-sided recording, a control unit generates a first correspondence relationship that associates a reference pattern with raster data of a first image in a medium transport direction, and a second correspondence relationship that associates the reference pattern with raster data of a second image in the medium transport direction, and, when the second image is recorded on a second surface, performs determination processing for determining whether the reference pattern detected by a detection unit and the raster data of the second image, which a recording unit records when the reference pattern is detected, match the second correspondence relationship.
Abstract: A flow channel substrate has pressure chambers, and the pressure chambers communicate with nozzle openings for ejecting liquid. Each of piezoelectric elements on the flow channel substrate has a piezoelectric layer, a pair of electrodes, and a wiring layer coupled to the electrodes. The wiring layer has an adhesion layer and a conductive layer on the adhesion layer. The adhesion layer contains at least one selected from nickel, chromium, titanium, and tungsten. The piezoelectric element has an insulating film at least between the wiring layer and the electrodes. The wiring layer and the electrodes of the piezoelectric element are coupled via contact holes created through the insulating film.
Abstract: A printer comprising a cover, and a stacker that is attached to the cover, the stacker being supported pivotably about a pivot axis on the cover between a protruding position where the stacker receives paper discharged from the printer, and a retracted position rotated a predetermined angle from the protruding position.
