ABSTRACT:
A jet drop copier utilizing a row of electrically scanned jets under multiplexed control of a row of side-by-side photosensing elements. An image of an original document is scanned across the row of photosensors, and the output signals from groups of adjacent photosensors are multiplexed to enable each such group to engage in time shared control of a single jet. The jets are directed toward a print receiving medium, which may be mounted on a rotating drum. Means are provided for causing image scanning movement and the movement of the print receiving medium to proceed in synchronism. A print head for producing the printing directs a row of jets toward a catcher and has a series of printing control electrodes for causing the jets to avoid the catcher on a selective basis. Sideward scanning of printing drops is produced by scanning electrodes comprising vertically spaced electrode elements. A scanning signal is applied to each of the elements with a phase shift corresponding to the time of drop flight from element to element.
