<p>A modular MEMJET printhead for a digital printer wherein a plurality of printhead modules (2) may be mechanically aligned using specifically designed frame (3) supporting the modules (2). The modules (2) are sealed units with four independent ink chambers that feed the inkjet nozzles in a printhead chip (8) which is bonded to a TAB film (6). The metal frame (3) has a plurality of mounting sites (19) for mounting respective printhead modules (2) to the frame (3) wherein at least one of the mounting sites (19) having mechanical adjustment mechanism for reducing input movements to effect minute adjustments of the position of the printhead module (2) with respect to the frame (3). The adjustment mechanism uses a system of levers, pivots and a grub screw for geared reduction of the input movements to minute adjustments (less than 100 micrometers) of the printhead module relative to the frame.</p> |
