摘要： Printer and print head capable of printing in a plurality of dynamic ranges of ink droplet volumes, and method of assembling same. A plurality of first nozzles are connected to a print head body, each first nozzle having a first orifice of a first size for ejecting an ink droplet having a first volume. The ink droplet volume is selected from a first dynamic range of volumes uniquely associated with each first nozzle. A plurality of second nozzles are also connected to the print head body, each second nozzle having a second orifice of a second size larger than the first size of the first nozzles for ejecting an ink droplet therethrough having a second volume larger than the first volume. The second volume is selected from a second dynamic range of volumes, which second dynamic range of volumes may be greater than the first dynamic range of volumes. In this manner, the printer and associated print head body are capable of printing in a plurality of dynamic ranges of volumes, so that a single printer can print either at low density levels or at high density levels with a minimum number of nozzles.

摘要： Imaging apparatus and method adapted to control ink droplet volume and void formation. The apparatus includes an ink jet print head having a nozzle for ejecting an ink droplet therefrom. A heater element is in heat transfer communication with the ink droplet for variably supplying heat energy to the ink droplet, so that the volume of the ink droplet is controlled as the heat energy is variably supplied to the ink droplet. A controller is connected to the heater element for variably controlling the heat energy supplied to the ink droplet. The controller variably controls the heat energy by variably controlling a plurality of voltage pulses sequentially supplied to the heater element. Moreover, in order to reduce the potential for void formation in the ink droplet, the pulses are spaced-apart by a predetermined delay interval. Suitable control of ink droplet volume and delay interval between pulses results in uniform print density and "gray-scaling" of each dot or pixel in the output image and also precludes void formation.

摘要： 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.

摘要： 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.
