ABSTRACT:
A pictorial ink jet printer is disclosed. The printer uses a linear array of nozzles each of which records a segment of a row of pixels in a given raster pattern. The pixel segment is recorded by electrostatically deflecting the ink drops from a nozzle to the pixels contained within the segment. The drops from adjacent nozzles are "stitched" or aligned to these ideal pixel positions by aligning the ink drop streams to drop position sensors. Two sensors are used for each nozzle. Preferably, adjacent nozzles share sensors. The sensors are spaced relative to each other to very close tolerances. Consequently, alignment of each nozzle to its two drop position sensors means that the drops from adjacent nozzles are aligned or "stitched."
