Modular printhead assembly with capping devices

摘要

A printhead assembly includes an elongate carrier. A plurality of printhead modules is serially positioned on the carrier. Each printhead module includes an ink supply arrangement mounted on the carrier and a printhead chip mounted on the ink supply arrangement to be fed with ink from the ink supply arrangement. A plurality of capping devices is mounted on the carrier. Each capping device is displaceable with respect to the carrier between an operative position in which the capping device caps the printhead chip and an inoperative position in which the printhead chip is uncapped.
