Abstract
An inkjet printer has a molded ink manifold bonded to a printhead by an adhesive film. The printhead has: (a) a plurality of nozzles formed on a frontside of a substrate, the nozzles being arranged in rows extending longitudinally along the substrate, each nozzle having a respective nozzle inlet; and (b) a plurality of ink supply channels extending longitudinally along a backside of the substrate. Each ink supply channel is configured for supplying ink from the backside to at least one corresponding row of nozzle inlets. Further, each ink supply channel is interrupted along its length by one or more transverse bridges. The transverse bridges provide the printhead integrated circuit with strength in a transverse direction.
