System for determining orifice interspacings of cooperative ink jet print/cartridges |
摘要 |
Ink jet printing apparatus of the type having a carriage that traverses a printing zone with a plurality of insertable print/cartridges includes a system for use in coordinating the transverse printing of such print/cartridges to compensate for variable transverse print/cartridge locations. The system employs an electrooptical scanner located along the transverse path of the carriage for signalling the passage of a print/cartridge feature(s) that are indicative precisely of an instantaneous horizontal position, vis-a-vis the scanner, of the orifice array of a passing print/cartridge; a carriage detector for periodically sensing and signalling the successive instantaneous positions of the carriage during its traversing movement; and means, responsive to signal inputs from the scanner and the carriage detector, for computing and storing horizontal location data for each print/cartridge orifice array.
