Abstract
A laminated ink distribution structure for a printhead has a number of layers adhered to one another with each layer including a number of ink holes formed therethrough. Each ink hole has communicating therewith a channel formed in one side of the layer and allowing passage of ink to a transversely located position upon the layer, the transversely located position aligning with a slot formed through an adjacent layer of the laminate. The laminated ink distribution structure is fixed to a distribution housing via which different inks are conveyed from an ink cassette. The laminated structure distributes the different inks to an array of print chips of a color printer.
Claims1
A method of distributing ink and air to print chips in a printhead assembly of a printer, the method utilizing a laminated ink distributing structure formed as a number of micro-molded layers adhered to one another with each layer including a plurality of ink holes formed therethrough, at least some of the ink holes in each layer communicating with a channel formed in one side of the said layer allowing passage of at least one of ink mini air to a transversely located position within the structure, which transversely located position aligns with an aperture formed through an adjacent layer of the structure via which at least one of ink and air pass to the print chips, the method including selectively supplying different inks to pre-determined ones of the holes to thereby transfer the different inks to the printhead chips as required and selectively supplying air to predetermined ones of the holes to thereby transfer air to the printhead chips as required.
