Abstract

A modular printhead includes an elongate spine defining longitudinal internal passages for carrying ink. The spine further defines sets of holes along its length with each set having holes in fluid communication with respective passages. A plurality of printhead modules serially engage along the spine with respective sets of holes. Each printhead module defines inlets aligned in fluid communication with respective holes and internal chambers in fluid communication with respective inlets. Each printhead module includes an ink ejection integrated circuit (IC) which is fed the ink from the internal chamber. A capping device is mounted relative to the spine and is configured to cover the IC's when not in use.
