  • Patent number: 6276774
    Abstract: An imaging apparatus capable of inhibiting inadvertent ejection of a satellite ink droplet and method of assembling same. The imaging apparatus comprises a print head transducer including a pair of sidewalls defining a chamber therebetween, the channel having the ink body disposed therein. The transducer is in fluid communication with the ink body for inducing a first pressure wave in the ink body in order to eject an ink droplet. A waveform generator is connected to the transducer for supplying voltage waveforms to the transducer, so that the transducer induces pressure waves in the ink body. However, the first pressure wave has a reflected portion formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to otherwise inadvertently eject unintended satellite ink droplets. Thus, a sensor is in fluid communication with the ink body for sensing the reflected portion and is connected to the transducer for inducing a second pressure wave in the ink body.

  • Patent number: 6089696
    Abstract: An ink jet printer capable of increasing spatial resolution of a plurality of marks to be printed thereby and method of assembling the printer. The printer comprises a print head body having a nozzle block including a plurality of adjacent ink channels of predetermined pitch "P" for printing an image on a receiver. The nozzle block is slidably disposed in the print head body and thus is movable relative to the print head body. A displacement mechanism is connected to the nozzle block for slidably moving the nozzle block a predetermined distance "P.sub.1 " less than pitch P. Before the nozzle block is moved, the channels are enabled in order to eject ink droplets which have pitch P for defining a first spatial resolution of the marks on the receiver. The displacement mechanism then moves the nozzle block the predetermined distance P.sub.1 to a second position. The channels are again enabled while the nozzle block is in this second position.

  • Patent number: 6047816
    Abstract: Printhead container and method. The container comprises an enclosure surrounding a printhead body having an ink channel terminating in a nozzle orifice. The ink channel has ink therein. The enclosure is capable of being pressurized to a predetermined internal pressure. The internal pressure acts on the ink to retain the ink in the channel, so that the ink is prevented from flowing along the channel and through the orifice. A one-way valve is in communication with the interior of the enclosure for ingress of a pressurizing medium into the interior of the enclosure, while avoiding reverse flow through the valve in order to allow sustained pressurization of the enclosure. Moreover, a support frame disposed in the enclosure may be provided, the frame defining a well sized to matingly receive the printhead body for constraining movement of the printhead body during transport of the enclosure.

  • Patent number: 6046822
    Abstract: Ink jet printing apparatus and method for improved accuracy of ink droplet placement on a receiver medium by compensating for jet direction variabilities between ink nozzles. More specifically, the invention is an ink jet printing apparatus and method for printing an output image on a receiver medium in response to an input image file having a plurality of pixels. The apparatus includes a print head and a nozzle integrally attached to the print head. The nozzle has a droplet placement characteristic (e.g., undesired placement of the droplet on the receiver medium) associated therewith. A waveform generator associated with the nozzle generates an electronic waveform including a plurality of electronic pulses to be supplied to the nozzle for adjusting the droplet placement characteristic. In this manner, the invention compensates for the undesired droplet placement characteristic, so that the droplet is accurately placed on the receiver medium irrespective of physical variabilities between nozzles.

  • Patent number: 6033059
    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.

  • Patent number: 5163075
    Abstract: The contrast of an electrographic image or a region of interest of an electrographic image having low contrast is enhanced by developing the electrographic image with toner using a development electrode which is biased to a potential which has a value near the average potential of the image but outside of the range of values of potential corresponding to image features selected for enhancement. The voltage potential of the electrographic image is measured to determine the average potential in the region of interest. The development electrode bias is set at a potential near the average potential but outside of the range of potentials corresponding to the image features selected for enhancement in the region of interest of the image. When developed with toner, the toner image has enhanced contrast. If the image is a xeroradiographic image, diagnostic capability of low contrast regions can be enhanced.
