Modular printhead assembly incorporating a capping device

摘要

A modular printhead assembly includes an elongate support structure. An ink feed member is mounted on the support structure. The feed member defines a number of ink channels, the ink channels extending in the direction of the support structure and being in fluid communication with an ink supply, the ink feed member having a plurality of outlet openings from which ink can be fed. A plurality of printhead modules is mounted, in a releasable manner, on the support structure to be positioned along a length of the ink feed member. Each printhead module has an ink delivery assembly that defines a mounting formation for an elongate printhead integrated circuit and a plurality of ink inlets in fluid communication with respective outlet openings of the ink feed member and an elongate printhead integrated circuit mounted in said mounting formation. A capping device is operatively arranged with respect to the support structure and displaceable between a capped position in which the integrated printhead circuits are capped and an uncapped position. An actuating mechanism is engaged with the capping device to displace the capping device between the capped and uncapped positions.
