摘要:
A printhead assembly for a pagewidth ink jet printer includes an ink storage assembly that defines at least one ink storage chamber. An elongate mounting member is mounted on the ink storage assembly to be in fluid communication with the, or each, ink storage chamber. At least one printhead module is mounted on the mounting member and has a carrier that defines a recess and a printhead chip received in the recess. The recess is in fluid communication with the mounting member so that ink from the, or each, ink storage chamber can be fed to the printhead chip.

The present invention provides a printhead module. The printhead module comprises a body defining a plurality of ink chambers. There is also provided a rib cage comprising a plurality of ribs and for mounting to the body. A gap is defined between each adjacent pair of ribs and a channel is defined transverse to the ribs. The printhead module further comprises a film for covering the rib cage and a printhead integrated circuit for mounting to the film in a location coincident with the channel. In use, ink passes from the ink chambers, along the gaps and into the channel before being fed to the printhead integrated circuit.

A modular printhead assembly includes an elongate chassis. A plurality of elongate printhead modules is serially arranged along and engaged with the chassis. Each end of each printhead module is shaped so that each adjacent pair of printhead modules forms a complementary fit. Each printhead module includes an elongate printhead configured to eject ink. Each printhead is oriented obliquely with respect to the longitudinal axis of the chassis. Each adjacent pair of printheads overlaps to enable continuous printing along the axis.

An ink jet printhead assembly includes a chassis. A number of printhead modules are mounted on the chassis. Each printhead module includes an ink distribution member that is attached to the ink reservoir. An elongate printhead chip is arranged on the ink distribution member to receive ink fed from the ink distribution member. The printhead modules are positioned on the chassis so that the printhead chips span a printing zone.
摘要:
An ink reservoir for supplying ink to an elongate printhead that includes at least one printhead chip, the ink reservoir defining a plurality of channels and having a plurality of sets of filling formations, each filling formation of each set being in fluid communication with a respective channel; wherein each filling formation is adapted such that in use the formation sealingly and releasably engages a hydrophobic, elastomeric collar on an ink supply device such that one ink chamber of the ink supply device is in communication with a respective ink channel of the reservoir via one collar.
摘要:
A printhead module is provided for an inkjet printhead assembly. The printhead module includes a support defining a plurality of internal ink chambers. An elongate ink distributor is mounted to the support. A subassembly includes a micro-electromechanical integrated circuit (IC) configured to eject ink and mounted to the distributor so that ink from the ink chambers can be distributed to the IC by the distributor. The support, distributor and subassembly are shaped to define complementary formations on opposite sides of the printhead module so that a pair of the printhead modules can be mated together.

A print engine assembly includes a support for a micro-electromechanical pagewidth print head. A single motor is controlled to dispense print media from a cartridge that is fast with the print head support and, at the same time, drive an air pump to direct air across the print head in order to keep it clear of debris. An air filter is provided to filter the air prior to it entering the air pump. The air is distributed to the print head support through a conduit that is formed in a molding which is shaped to receive the air pump.
摘要:
A modular printhead assembly is provided for an inkjet printer. The modular printhead assembly includes an elongate chassis defining a plurality of slots. An elongate ink reservoir is fast with the chassis. The ink reservoir defines: a plurality of longitudinally extending ink channels for storing respective types of ink, a plurality of spaced apart sets of ink outlets with the ink outlets of each set being in fluid communication with respective ink channels, and a plurality of receiving formations located along the ink reservoir which can receive a plurality of printhead modules. The plurality of printhead modules is configured to releasably engage with respective sets of ink outlets and print ink supplied from the ink reservoir. Each printhead module includes a plurality of resilient fastening legs configured to be received within the receiving formations at particular locations during engagement so that access to the legs is thereafter enabled through the slots to facilitate disengagement of the printhead modules from the ink reservoir.
