Abstract: Printer apparatus and method. The apparatus includes a substrate having a plurality of spaced-apart pairs of selectively actuatable side walls defining respective channels therebetween of different depths. Each channel receives an associated one of a plurality of ink bodies therein and the substrate is formed of piezoelectric material responsive to electric stimuli. The pairs of side walls are preferably separated one from another by means of an intervening cut-out for reducing mechanical coupling between the ink channels. A cover plate is connected to the substrate and has a plurality of orifices therethrough in registration with respective ones of the channels such that the orifices are off-set one from another. Accordingly, in one embodiment of the invention, the channels have different depths and, therefore, the orifices, which are in registration with the channels, are off-set one from another to accommodate the different depths of the channels. A selected ink channel, which belongs to a first group of channels having a first predetermined depth, pressurize as its pairs of side walls are actuated. Also, a non-selected ink channel, which belongs to a second group of channels having a second predetermined depth, remains unpressurized as the selected channel is actuated. Moreover, the two groups of channels are interleaved. The channels of the first group are actuated at a later time that the channels of the second group as the printhead traverses a receiver medium. This feature of the invention reduces mechanical and hydraulic coupling between channels because actuation of selected channels belonging the two groups are spaced-apart in time.

Abstract: A mandrel for forming a nozzle plate having orifices of precise size and location, and method of making the mandrel. The nozzle plate is formed by overcoating a substrate with a metal film. The film is covered with a photoresist material. Portions of the photoresist are exposed to light passing through a photomask having an annular light-transparent regions, of precise diameters and pitch. The photoresist is subjected to a developer bath which dissolves the photoresist exposed to the light, thereby revealing selected portion of the film. Next, an etchant is brought into contact with the film for etching-away the film so as to an annular opening in the film defining a column of precise diameter at the center of each opening. A new photoresist layer is then applied to the film. Portions of the new photoresist layer is exposed to light passing through a second photomask. The new photoresist material is then subjected to the developer which dissolves the new photoresist material to reveal the film beneath the photoresist and selected areas of the substrate. A second etchant is applied to create an annular recess extending into the substrate. The column resides at the center of the recess. This forms the nozzle plate mandrel. Next, a metal layer that will form the nozzle plate is deposited onto the film and grows into the recess to substantially fill the recess, except for the space occupied by the column. The finished nozzle plate is separated from the film/substrate structure to obtain orifices with precise diameters and pitch.

Abstract: A platen-driven thermal dye printer mechanism (1), and more particularly to a cone-shaped scuff roller (7) which aligns a dye print receiver media sheet (2) with the receiver guide wall (8) during printing in a reciprocating direction (5). Using at least one conical shaped scuff roller (7) at one end of a platen roller (4) to transport the precut dye receiver media (2). The conical scuff roller (7) presses the back surface of the dye receiver media (2) against the non-imaging margin of the thermal dye printer mechanism (1). The invention uses a smooth guiding plate (28) and platen (4) thus, preventing scratches on the front surface of the receiver media (2). The invention is not subject to costly breakdowns, in that it uses the clockwise and counter-clockwise rotation of the platen (4) to provide perfect alignment of the receiver media (2) and printer head (9).
