Abstract
A printhead is provided having an elongate support having a plurality of internal webs protruding from a base section to define a plurality of parallel fluid supply channels, a shim supported by the support and defining a plurality of rows of openings through which fluid from respective supply channels is supplied, and a plurality of elongate printhead modules supported serially on the shim. Each module defines a plurality of fluid supply passages through which fluid passes to fluid ejection nozzles from respective rows of the openings. Either end of each module defines complementary formations such that adjacent modules nest together.

An inkjet printhead assembly comprising:
- a support structure having a plurality of ink supply channels;
- a plurality of print modules mounted on the support structure in an overlapping arrangement, each print module comprising:
- a printhead chip carrier having a plurality of carrier inlet channels, each carrier inlet channel receiving ink from a respective ink supply channel and supplying ink to an ink delivery slot extending lengthwise along the printhead chip carrier;
- and
- one and only one printhead chip mounted on the printhead chip carrier, the printhead chip receiving ink from a plurality of the ink delivery slots,
- wherein:
- a shim is positioned between the support structure and the print modules, the shim having a plurality of openings allowing passage of ink from the ink supply channels to the carrier inlet channels.
A method of delivering one or more inks to a plurality of printhead chips, the method comprising the steps of:
- providing the ink in a plurality of ink supply channels of a support structure;
- delivering the ink from the ink supply channels to respective print modules mounted on the support structure in an overlapping arrangement;
- converging the ink from ink inlets at opposite sides of each print module towards a plurality of ink delivery slots via tapered carrier inlet channels;
- and
- delivering the ink from the plurality of ink delivery slots in each print module to a respective one of the printhead chips,
- wherein the ink passes through openings in a shim positioned between the support structure and the print modules.
