Abstract

A high resolution ink jet printing system includes a plurality of substantially identical print/cartridges each having an orifice plate comprising: (i) an array of orifices located in a precisely interspaced relation and (ii) a detent means precisely located with respect to the orifice array. The system provides a carriage for insertably supporting such print/cartridges and for traversing them along a linear print zone in a direction substantially perpendicular to the direction of print medium feed. The carriage has reference surfaces for respectively positioning the detent means of inserted print/cartridges at predetermined locations that are precisely vertically offset relative to the direction of carriage traverse. In such system the printing droplets from the vertically offset orifice arrays of inserted and indexed print/cartridges will be vertically interlaced in each printing traverse of the carriage.
