摘要： An inkjet drop ejection system comprises a combination of printhead components and ink, mutually tuned to maximize operating characteristics of the printhead and print quality and dry time of the ink. Use of a short shelf (distance from ink source to ink firing element), on the order of 55 microns, provides a very high speed refill. However, it is a characteristic of high speed refill that it has a tendency for being over-damped. To provide the requisite damping, the ink should have a viscosity greater than about 2 cp. In this way, the ink and architecture work together to provide a tuned system that enables stable operation at high frequencies. One advantage of the combination of a pigment and a dispersant in the ink is the resultant higher viscosity provided. The high speed would be of little value if the ink did not have a fast enough rate of drying. This is accomplished by the addition of alcohols or alcohol(s) and surfactant(s) to the ink. Fast dry times are achieved with a combination of alcohols, such as iso-propyl alcohol with a 4 or 5 carbon alcohol or with iso-propyl alcohol plus surfactant(s). One preferred embodiment of a short shelf (90 to 130 microns), ink viscosity of about 3 cp, and surface tension of about 54 provides a high speed drop generator capable of operating at about 12 KHz. Reducing the shelf length to about 55 microns, in combination with rotating the substrate at an angle to the scan direction, permits maximum drop generator operation as high as about 20 KHz. As a consequence of employing pigment-based inks, high optical densities are realized, along with excellent permanence (no fade and better waterfastness), and good stability. The combination of preferred ink and pen architecture provides good drop generator stability.

摘要： An inkjet printhead includes multiple printing elements grouped in sets about an ink refill channel. Each printing element includes a nozzle chamber and firing resistor. Respective nozzle chambers are located at a staggered distance away from the ink refill channel. A printing element's feed channel couples its nozzle chamber to the ink refill channel. A pinch point defined by barrier walls occurs along the feed channel. Converging and diverging half angles for each barrier wall of a given printing element are the same. Such angles differ among a plurality of printing elements. The specific angle for a given printing element defines where along the feed channel the pinch point occurs. The specific angle is prescribed according to the distance from a given printing element's firing resistor to the ink refill channel. A certain angle is used for a certain resistor stagger position to provide ink refill balancing among printing elements.

摘要： A fluid ejection device comprising a substrate having a first surface, and a fluid ejector formed over the first surface. A top layer is also formed over the first surface of the substrate and defines a chamber about the fluid ejector. The top layer also defines a fluid channel that directs fluid into the chamber. In one embodiment, a barrier feature is positioned within the fluid channel, and has a height that is less than the height of the fluid channel.

摘要： A thermal ink-jet pen which includes a tuned printhead for ejecting droplets of ink onto a print medium is provided. The printhead comprises (a) a plurality of resistive elements, (b) a plurality of nozzles through which the droplets of ink are ejected, (c) a plurality of drop ejection chambers, (d) a plurality of ink feed channels, each provided with an entrance defined by a pair of projections on either side thereof, and (e) an ink refill slot operatively associated with the plurality of ink feed channels, the ink refill slot defined by an edge to provide a shelf from the edge to the ink feed channels. The plurality of resistive elements is divided into sets, with each resistive element staggered a different distance from the edge. Each ink feed channel within a set is provided with a different critical dimension value, the critical dimension comprising at least one selected from the group consisting of (1) width of entrance to channel, (2) width of the channel, (3) length of the channel, and (4) distance of the resistive element to the terminus of the channel. The critical dimension is related to distance of the resistive element from the edge. By providing each set of resistive elements with different widths, the damping of the pen is improved and all the nozzles have substantially the same refill speed.
