Printhead having nested modules

A modular printhead is disclosed which includes an elongate channel and a plurality of printhead modules. The printhead modules are received in the elongate channel. Each printhead module has a carrier, an elongate ink delivery member mounted in the carrier and a printhead. The elongate ink delivery member defines longitudinal conduits, each conduit carrying a respective ink. The elongate ink delivery member further defines sets of apertures, each set of apertures including apertures which are each in register with a corresponding conduit. The printhead includes inkjet nozzles, each inkjet nozzle being in fluid communication with a respective conduit.

Modular printhead with a plurality of printhead modules

A printhead module is provided for an inkjet printhead assembly. The printhead module includes a support. An elongate carrier is mounted to the support. The carrier defines a plurality of transverse ribs and an ink channel located between the ribs. A subassembly includes a micro-electromechanical integrated circuit (IC) configured to eject ink. The subassembly is mounted to the carrier so that the support, carrier and subassembly define a plurality of sealed ink chambers which can feed ink to the IC via the ink channel.

Printhead module for an inkjet printhead assembly

An inkjet printhead assembly includes an elongate ink supply body defining a plurality of ink supply channels; an elongate cradle member defining a plurality of rows of apertures, the elongate cradle member being fastened to the elongate ink supply body to communicate ink within the ink supply channels through respective ones of said rows of apertures; and a plurality of printhead segments each having a carrier defining a plurality of rows of ink supply passages arranged in alignment with respective apertures of the cradle member, each printhead segment further having an elongate ink ejection printhead mounted to the carrier in fluid communication with the ink supply passages. Each carrier defines a complementary formation for mating serially with the cradle member.

A printhead module for a wide format pagewidth inkjet printer comprises a carrier mountable on a chassis, said carrier being configured for abutment with a carrier of an adjacent printhead module; at least one printhead integrated circuit mounted on the carrier, said at least one printhead integrated circuit including a plurality of ink ejection nozzles and drive circuitry for driving actuators in the ink ejection nozzles; and a connection zone defined in the carrier for electrically connecting said at least one printhead integrated circuit to control circuitry. The ink ejection nozzles are supplied with ink from an ink distribution arrangement, and the printhead module is removably mounted to the ink distribution arrangement.

Printhead module for wide format pagewidth inkjet printer

A printhead is provided having an assembly of printhead modules. Each printhead module has a support defining fluid chambers, a fluid distributor on the support, and an integrated circuit on the distributor so that fluid in the chambers is distributed to the fluid ejection nozzles of the integrated circuit by the distributor. The support and distributor of each printhead module are shaped to define complementary formations on opposite sides of that printhead module so that the printhead modules are mated together in an angled fashion with the integrated circuits of the mated printhead modules abutting together and diagonally overlapping to define at least one row of fluid ejection nozzles of the printhead.
