摘要： Disclosed is an ink delivery system for high throughput commercial inkjet printing devices. The ink delivery system includes a high speed ink ejection printhead with a large number of nozzles and an ink flow design which provides for improved printhead cooling. The printhead design achieves high ink ejection rates by having a very short inlet channel length which is made possible by having nozzles with a constant distance from the edge of the printhead. In order to accommodate this constant distance from the edge of the printhead the entire array of nozzles is disposed at a angle relative to the direction normal to the scan direction. An impinging ink flow against the back of the printhead is provided to limit the temperature of the printhead. A bubble collection chamber to increase the life of the printhead and a pressure regulator to provide ink at a controlled pressure to the printhead may also be provided. Pressurized ink may be provided so that ink pressure may be properly controlled even during peak usage.

摘要： An inkjet print cartridge uses at least one groove to supply ink from an ink reservoir to the fluid channel, which includes an ink ejection chamber, such that foreign particles within the ink supply are filtered out by the grooves so as not to block the fluid channel. In one embodiment, a barrier layer between a substrate and nozzle member contains the ink ejection chamber which is in communication with a plenum via a flow restrictor, such as pinch points. The nozzle member includes an array of orifices and grooves. The substrate includes two linear arrays of ink ejection elements, such as heater elements, and each orifice in the nozzle member is associated with an ink ejection chamber and ink ejection element. A plurality of grooves is likewise associated with each plenum. The plurality of grooves in the nozzle member supply ink into each plenum, which in turn supplies ink to the ink ejection chamber.

摘要： Described is an ink delivery system is that utilizes a filter carrier to simplify the process of attaching the filter. The filter carrier is an element that has a conduit that is substantially surrounded by a filter attach surface. The filter is attached to this surface, such that substantially all fluid passing through the conduit is filtered. The filter carrier is installed into a housing upon which a printhead is mounted. The filter then divides the ink delivery portion of the housing into upstream and downstream sections such that ink flows from the upstream portion through the filter to the downstream portion and to the printhead. The separation of the filter sing from the cartridge housing provides more freedom of material selection for both the cartridge housing and a good heat staking material for the filter carrier. The separation also greatly simplifies the molding of the rigid cartridge housing. Also, the filter staking process is greatly simplified when it is performed external to the cartridge housing. Also provided is the ability to have an adjustable air warehouse volume to accommodate various out-gassing rates of different print usages cartridge usages.

摘要： An ink conduit for an inkjet printhead is disclosed which increases the velocity of ink flowing across the back surface of a substrate and into ink ejection chambers. The increased velocity of ink across the back surface of the substrate results in greater removal of heat from the substrate. This increased ink velocity is achieved by providing narrow ink conduit openings proximate to the back surface of the substrate. To avoid air bubbles becoming trapped in the relatively narrow ink conduit, one or more pockets are formed to allow the accumulation of bubbles, so that the bubbles do not affect the ink flow through the ink conduit and into the ink ejection chambers.

摘要： Ink-jet printer inks wherein kogation reduction is accomplished by the addition of phosphonate additives to the inks. In a preferred embodiment, the following are utilized: sodium salt of amino tri(methylene-phosphonic acid), 1-Hydroxyethylidene-1,1,-diphosphonic acid, diethylene triaminepenta(methylenephosonic acid); and potassium salt form of hexamethylenediamine tetra(methylene phosphonic acid). Although in the examples disclosed herein, the salt form of the phosphonic acids were used, the acid form of the phosphonic acid can also be used provided the pH of the final inks are adjusted to desirable levels. Use of the above listed additives essentially eliminate kogation for the life of the pens, such as those used in Hewlett-Packard Company's thermal inkjet printers.

摘要： The present invention provides an ink feed architecture for an inkjet printhead that extends the life of firing resistors. Two separate ink channels lead to each firing chamber. The ink channels are asymmetric with respect to the firing chamber, causing an asymmetric flow pattern that pushes the collapsing drive bubble and distributes the associated high pressure spikes over the resistor surface. This increases the life of the resistors.
