US Patent 7766453 Printhead with overlapping arrays of nozzles

The printhead for a digital ink jet printer where arrays of nozzles (3) are arranged in an overlapping configuration to preserve continuity between the printing from adjacent arrays (3). Each array (3) receives print data from TAB films (6). The TAB films (6) extend from the same side of each array (3) to allow for a relatively compact printhead design. The arrays (3) are configured so that predominantly all of the arrays (3) have, at most, one end obscured by the end of an adjacent array (3). This reduces the amount that the TAB films (6) need to narrow or ‘neck’ in order to avoid the obscuring adjacent end.
