Abstract

The construction of pagewidth arrays 10 of marking elements, such as, for exam le, thermal ink 'et arrays, could be accomplished by composing smaller modules could be butted edge-to-edge, stacked in an interleaved fashion like bricks, or assembled on opposite sides of a central registration bar 16. For ink jet arrays, a key problem is bringing the active transducer elements to within a small fraction of a pixel of the desired position on opposite sides of the "joints" or abutted edges 14. The allowable tolerance is only a few microns. An additional problem for an ink jet system is the differing aerodynamic behavior of the end marking elements compared to those in the center of an array when a stacked approach is used as in Figures lb and lc.
