Printer with a self-cleaning inkjet printhead assembly

摘要

An inkjet printer includes a printhead assembly having a carrier. An ink supply assembly is mounted on the carrier and defines a plurality of printhead integrated circuit receiving formations that are each dimensioned to engage a printhead integrated circuit and a plurality of ink supply conduits that terminate at the formations to supply ink to printhead integrated circuits engaged with the formations. A plurality of inkjet printhead integrated circuits is engaged with respective said formations to receive the ink via passages defined by the printhead integrated circuits in fluid communication with respective ink supply conduits. The ink supply assembly further defines a gas flow path that terminates at each formation, the ink supply assembly being connectable to a pressurized gas supply so that gas can be directed over each printhead integrated circuit to inhibit the build-up of dust and debris on the printhead integrated circuits.
