A pagewidth printhead for an inkjet printer includes an elongate support; a plurality of printhead modules supported by the support, each printhead module comprising rows of unit cells, each unit cell comprising a nozzle through which ink is ejected and an actuator for ejecting ink from the nozzle; and an engagement mechanism having complementary formations defined on opposite edges of each printhead module to engage the printhead modules together in series along the support. The engagement mechanism includes a biasing means configured to press the serially arranged printhead modules together, the biasing means including at least one compression spring. A gap is defined between the unit cells of adjacent printhead modules, the gap extending obliquely with respect to the support.
