A wide-format inkjet print engine includes an elongate chassis. A channel member is mounted on the chassis. The channel member and the chassis span a print zone. An ink reservoir assembly is mounted in the channel member and defines at least one ink reservoir that extends a length of the channel member and is connectable to an ink supply. A plurality of printhead modules is mounted on the ink reservoir assembly, each printhead module having a printhead integrated circuit mounted on a carrier, each printhead integrated circuit having a plurality of nozzle arrangements incorporating micro-electromechanical actuators for ejecting ink from respective ink chambers. A plurality of print engine controllers is mounted on the chassis. Each print engine controller is electrically connected to a number of the printhead integrated circuits and is configured to control operation of the number of the printhead integrated circuits.
