Abstract: INK JET COPIER An ink jet copier is provided with a document scanner which scans a document to be copied one line at a time producing non-coded binary data. The binary data is inserted in storage in a predetermined arrangement. Stored data is removed from selected predetermined locations in accordance with an algorithm and applied to a plurality of ink jet nozzles arranged in multiple linear arrays about the circumference of a rotating paper drum. The data signals selectively applied to the ink jet printers control the deposition of ink on the paper supported on the rotating drum to cause the reproduction of the original scanned image on a predetermined interlaced basis.

Abstract: MEDIA SKEW COMPENSATOR A pair of detectors provide signals coincident with the circumferential and axial edges of a print medium mounted on a rotating media support drum. These signals are used to control counters which respond to an emitter circumferentially disposed with respect to the drum to generate a preset or offset signal value and a gate signal to accommodate axial and circumferential misalignment of the print medium on the drum.
