Abstract: A fluid jet assisted ion projection copier including a marking head incorporating an array of thin film ion modulating electrodes and photosensors integrated upon a single substrate. An optical projection system places incremental images of light and dark areas from an original to be copied onto the ! array. The marking head is mounted upon the ion projection housing, adjacent an outlet channel thereof for controlling the passage of ions out of the housing in accordance with the projected pattern of light and dark areas.

Abstract: The present invention is a digital imaging system (30) for a copier that comprises a full-frame, two-dimensional sensor array (42) to capture a document's (32) image and a full-frame output light valve with backlight (36) to flash expose the image onto a photoreceptor belt. The document is flash exposed to illuminate the page (32) and the full-page image is captured by the full-frame, two dimensional sensor array (42). The sensor array (42) then reads out the digital image data in response to a driver (46). The data is then input into the full-frame digital output light valve (50). The driver (46) provides for the synchronous control of the system. Optionally, an electronic subsystem may perform digital image processing according to user demand - before the data arrives at the output light valve (50). After image processing (if any), the digital data, supplied to the full-page output light valve (50), forms a pattern on the display according to the data. The patterned image is then flash exposed by a backlight (36), through the light valve (50), and onto a photoreceptor (56).
