Printhead unit assembly for use with an inkjet printing system

摘要

Features for various embodiments of a self-contained printhead unit, including an on-board fluidic system, quick-coupling electrical and pneumatic interfacing, in conjunction with the features of various embodiments of a kinematic mounting and air bearing clamping assembly, as well as contactless integration to a waste assembly, together provide for the ready interchangeability of a plurality of printhead units in a printing system during a printing process, while at the same time preventing cross-contamination of a plurality of end-user selected inks contained in each of a plurality of printhead units.

主权项

1. An industrial inkjet printing system comprising:
a gas enclosure-system comprising a gas enclosure assembly defining an interior; and a printing system enclosed within the interior of the gas enclosure assembly, said printing system comprising:
a printhead unit comprising:
a fluidic system comprising:
a fluidic manifold block assembly, wherein the fluidic manifold block assembly comprises a fluidic manifold block having a plurality of channels fabricated therein and at least one fluidic manifold block assembly component selected from a valve, a reservoir, a printhead, and a waste system;a primary dispensing reservoir; anda printhead assembly having at least one printhead;a substrate support apparatus for supporting a substrate; anda motion system for controlling the position of the printhead unit relative to the substrate, wherein the motion system is configured to receive the printhead unit in a printhead mounting and clamping assembly comprising a baseplate configured to accept the printhead unit, and a support arm operably connected to the motion system and configured to receive the baseplate.
