Patent ID: 7891767

Claim:
A wide format print assembly comprising: a plurality of printed circuit boards (PCB's); a plurality of printhead modules connected to each of the PCB's respectively, each printhead module having a printhead integrated circuit (IC) comprising a plurality of micro-electromechanical nozzle arrangements on a wafer substrate for operatively ejecting printing fluid onto a print medium, the micro-electromechanical nozzle arrangements on all the printhead modules defining a print zone in which the micro-electromechanical nozzle arrangements are capable of simultaneously ejecting printing fluid onto the print medium, the print zone extending at least 38.4 inches transverse to print medium feed direction; a capping device for each of the printhead modules respectively, each of the capping devices being displaceable between a capping position to cap the nozzle arrangements and an uncapping position where the nozzle arrangements are exposed for printing; wherein, each of the PCB's has at least one print engine controller for receiving print data for the printhead IC's corresponding to the PCB, the at least one print engine controller being configured to synchronize with the print engine controllers on the other PCB's.
