Abstract: A method of operating an ink jet printer including printing a first image having substantially solid fill regions on a transfer surface disposed on a print drum, printing a second image on the first image, wherein the second image comprises solid or dithered fill regions that correspond to portions of some of the solid fill regions of the interlaced image, and wherein the second image has a dot density that is less than a dot density of the first image.

Abstract: A drop emitting device including a first linear array of columnar arrays of first nozzle pairs and a second linear array of columnar arrays of second nozzle pairs, wherein the first linear array and the second linear array extend along an X-axis, and wherein the second linear array is adjacent the first linear array such that each first nozzle pair has an associated second nozzle pair displaced therefrom along a Y-axis that is orthogonal to the X-axis. The columnar arrays of first nozzle pairs and the columnar arrays of second nozzle pairs extend obliquely to the X-axis.

Abstract: A drop emitting device including a linear array of first finger manifolds interleaved with a linear array of second finger manifolds to form a composite linear array of finger manifolds. The composite linear array of finger manifold extends along an X-axis, and the finger manifolds extend obliquely to the X-axis. A plurality of drop generators are fluidically coupled to the finger manifolds.

Abstract: Acoustic filters for use in an ink jet print head are disclosed. The ink jet print head defines a plurality of operating plates held together in a superimposed relationship forming an ink jet print head defining a plurality of ink manifolds, ink inlets, ink drop-forming orifices and a plurality of acoustic filters. The acoustic filters are a plurality of compliant areas connected by an acoustic filter constriction aperture and a plurality of separate compliant areas all connected to ink manifolds for suppressing unwanted frequencies during print modes.

Abstract: A piezoelectric transducer for use in an ink jet print head is disclosed. The ink jet print head defines an ink pressure chamber that further defines a chamber aperture having an overlaying flexible diaphragm. The piezoelectric transducer has a top side, an under side secured to the flexible diaphragm and an outer perimeter sized and positioned to overlap the chamber aperture wherein the overlap improves process capability and reduces voltage sensitivity.
