Abstract: A constant electric field is applied to a drop on demand print head using coincident force address of selected ink drops. This field can be generated by applying one electric potential to the print head, and a different electric potential to a platen which lies on the opposite side of the recording medium. This field does not need to be modulated, or turned on for each drop to be ejected. As a result, a simple high voltage power supply can be used to generate the electric field. No high voltage switching equipment is required. Also, the spacing between nozzles can be small, as the field applied to a nozzle does not need to be separated from fields applied to adjacent nozzles. The electric field is set to be insufficient to cause ink drops to be drawn from the print head when the ink in the nozzles in the quiescent position. The drop selection method causes the ink meniscus of selected drops to protrude from the front surface of the print head.

Abstract: A method of combining at least one customer generated digital image to form a merged image and/or text with at least one prestored digital image. The prestored digital image has a predetermined location where the customer generated digital image may be placed. A design characteristic is determined from an item to be associated with the merged image. The customer generated digital image or the prestored digital image is modified in accordance with the design characteristic so as to form a first modified digital image that is then combined with the other of the customer generated digital image or the prestored digital image so as to form a newly merged digital image. The newly merged digital image is the merged image sent to an output device for printing.

Abstract: An interline sensor is constructed using photocapacitors. The vertical shift register of the interline sensor is operated in a uniphase mode, i.e., holding one of the two phase (.phi.2) at a D.C. potential while fluctuating the other phase (.phi.1) between a voltage that is sufficiently above and below that D.C. potential to facilitate transfer of charge from one phase to the next. The uniphase mode is facilitated by a single electrode, an indium tin oxide electrode, that covers both the phase that is held at a constant D.C. potential and the photodetector having photocapacitor charges. The charges are transferred from the photocapacitors to the vertical shift register by a third level clock into (.phi.1) adjacent the photodetectors utilizing the same ITO electrode for phase 2 of both the vertical and horizontal CCD shift registers is also proposed.

Abstract: The present invention is for an imaging processor for thermal print medium. The image processor comprises a vacuum imaging drum (110) for holding thermal print medium (40) and donor sheets (120) in registration on the imaging drum (110). A printhead (200) moves along a line parallel to a longitudinal axis (X) of the imaging drum (110) as the imaging drum (110) rotates. The printhead (200) receives information signals and produces radiation which is directed to the donor (120) which causes dye to transfer from the donor (120) to the thermal print medium (40). When the imaging drum (110) is rotated in a first direction, a direct image is produced. When the direction of the imaging drum (110) is reversed, a mirror image is produced.

Abstract: A liquid ink, drop-on-demand printhead includes a substrate having a plurality of drop-emitter orifices, an ink channel coupled to each of the orifices for delivery of a body of ink to the orifices at a pressure above ambient, thereby forming an ink meniscus at the orifices. Drop selection is effected by selectively delivering heat to ink which has been delivered to selectively addressed ones of the orifices, thereby causing a difference in meniscus position between ink in addressed and non-addressed orifices. A heater is suspended in each ink meniscus close to its surface when the meniscus is at its position in a non-addressed orifice, the heater being effective to heat the meniscus and to thereby reduce surface tension of the meniscus at selectively addressed orifices.
