摘要： This present invention is embodied in a printing system for a printhead portion of an inkjet printer. The printing system of the present invention includes a filter, coupled between an ink supply and an inkjet printhead. A filter member having a plurality of holes can be coupled between the ink supply and the microscreen filter. Alternatively, the filter can be a thermally efficient filter comprised of a filter integrated with a heat transfer device and can be coupled to the inkjet printhead.

摘要： An ink-jet swath printer employing a cartridge with a spring bag primary reservoir and an auxiliary ink reservoir interconnected via a tube to form a closed ink replenishment system. The primary reservoir creates a negative pressure which draws ink from the auxiliary reservoir as ink is expelled from the cartridge printhead during printing operations. The auxiliary reservoir can either be mounted on the cartridge carriage or on the printer body. The auxiliary reservoir is a large capacity collapsible bag mounted below the level of the printhead to establish an ink pressure head at the primary reservoir connection which is not so large as to destroy or diminish the negative pressure and allow ink to drool from the printhead, yet is sufficient to permit replenishment of the primary reservoir to avoid printhead ink starvation.

摘要： A circuit for controlling the power applied to the heater resistor of a thermal inkjet printer printhead wherein the heater resistor is connected to a first source of current. The inventive circuit includes a first transistor having a first terminal connected to the heater resistor, a second terminal connected to a return path for the heater resistor and a simple circuit for maintaining a constant voltage at a third terminal of the transistor. In a particular embodiment, the circuit for maintaining a constant voltage at the third terminal of the transistor includes a diode connected between the second and third terminals and a resistor connected between a second source of current and the third terminal of the transistor. In the illustrative embodiment, the transistor is a bipolar NPN transistor and the anode of the diode is connected to the base terminal thereof. In the best mode, the diode is fabricated by connecting the base and collector terminals of a second transistor fabricated on a substrate with the first transistor. The invention provides a simple, low cost, reliable system for controlling the power applied to the heater resistor of a thermal inkjet printhead which consumes little power.
