Inkjet printer having ink distribution stack for receiving ink from ink ducting structure

摘要

A printhead assembly includes an ink distribution assembly including an ink distribution molding, the ink distribution molding including a plurality of first ducts; at least one printhead integrated circuit in fluid communication with the ink distribution assembly; and a rotary platen having at least three surface, each surface for providing one of a platen surface, capping portion, and a blotting portion. The ink distribution assembly further includes a plurality of second ducts acutely angled with respect to the plurality of first ducts, a plurality of transfer ports facilitating fluid communication between the plurality of first ducts and the plurality of second ducts, and a plurality of ink inlet ports facilitating fluid communication between an ink cassette and the plurality of first ducts.

1. An inkjet printer comprising:
a plurality of ink reservoirs, each ink reservoir containing a different colored ink; and a printhead assembly in fluid communication with the ink reservoirs, the printhead assembly comprising: an ink ducting structure including a plurality of first ducts extending substantially along a length thereof, each ink reservoir being in fluid communication with a respective one of the first ducts; and an ink distribution stack having three ink distribution layers, the ink distribution stack receiving, in an uppermost inlet layer, each of the different colored inks from the ink ducting structure and distributing the different colored inks to each of a plurality of printhead chips, wherein the uppermost inlet layer has a plurality of ink inlet holes in fluid communication with the first ducts via a plurality of second ducts defined in the ink ducting structure, the second ducts being non-parallel with the first ducts and serving to duct the different inks from the relatively widely spaced first ducts to the relatively narrowly spaced ink inlet holes.
