摘要:
The invention relates to improved nozzle plate designs for ink jet printers and to apparatus and methods for making the nozzle plates (10). The nozzle plates (10) of the invention are made from a polymeric material having a thickness sufficient to provide a plurality of flow features (12,14) and nozzle holes (16) aligned substantially along opposed edges of the nozzle plate (10) wherein the flow features (12,14) are ablated in the nozzle plates (10) with depths which provide decoupling of the flow features (12,14) from the nozzle holes (16) so that the flow features (12,14) and nozzle holes (16) can be independently designed in order to optimize the nozzle plate to provide improved performance.

Disclosed is an ink jet printhead apparatus for modulating drop size. Drop size modulation is achieved by providing an ink jet printhead chip for use in an ink jet printhead having a cavity in communication with a supply of ink and a nozzle. The chip includes an actuator (52) having a first active section (54) and a second active section (56). The first and second active sections are positioned at a substantially equal distance from the nozzle.

The invention provides improved methods for making ink jet printer nozzle plates and to nozzle plates made by the method. In the method, a polymeric film having a polymeric layer, an adhesive layer and a protective layer over the adhesive layer is ablated in order to produce flow features comprising ink flow channels (16), firing chambers (14), nozzle holes (18) and an ink supply region (24). Once the flow features are formed, the protective layer is removed from the polymeric film so that the nozzle plate can be attached to a semiconductor substrate. In the method a portion (26) of the polymeric material in the ink supply region (24) remains substantially unablated in order to reduce the debris produced during the ablation step. By reducing the amount of debris, removal of the protective layer after ablation is enhanced.

A baffle assembly (10) for insertion into an ink supply reservoir (12) includes a first baffle plate (14) having a first end and a second end, wherein a first end plate (18a) is coupled to the first end of the first baffle plate and a second end plate (18b) is coupled to the second end of the first baffle plate. The first baffle plate, the first end plate, and the second end plate form an integral structure. When the baffle assembly is inserted into the ink supply reservoir, a distance, "b", between the first baffle plate and an adjacent side-wall of the ink supply reservoir satisfies the inequality relationship b

An ink jet print cartridge is provided for use in an ink jet printer. The cartridge comprises a printhead including a heater chip (50). The printhead is adapted to generate ink droplets in response to the heater chip receiving energy pulses from a printer energy supply circuit. A peltier effect cooling cell (70) is associated with the heater chip for cooling the heater chip. The cooling cell receives current from the printer energy supply circuit as a function of energy flow to the heater chip.

An ink jet printer cartridge assembly including a cartridge body (11) with at least one ink chamber from which ink flows to a print head. A standpipe (14) in the ink chamber includes an opening (13) therethrough for the flow of ink to the print head, and a filter cap (17) is secured on the top of the standpipe to limit the introduction of air bubbles and particulate matter in the flow of ink toward the print head. The filter cap includes a mesh material (18) formed into a dome-shaped configuration and an elastomeric material (19) molded about the periphery of the mesh portion, with the elastomeric material being received around the top portion of the standpipe.
