摘要： A small form factor printhead and a thermal ink jet printer containing the reduce form factor printhead. The printhead includes an ink reservoir body having four side walls connected to a bottom wall. An ink supply port is disposed in the bottom wall. An ejection head is attached to an exterior surface of the bottom wall, wherein the ejection head is in ink flow communication with the ink supply port. A flexible circuit is electrically connected to the ejection head and is attached to the exterior surface of the bottom wall and an exterior surface of one of the four side walls. A cover is attached to a distal end of the four side walls opposite the bottom wall. A filter is attached adjacent to an underside of the cover.

摘要： An ink cartridge includes a main body, a head part, a first hole, a label, and a second hole. The main body stores ink. The head part is provided on the main body and has a plurality of nozzles for ejecting ink. The first hole has a tapered shape which narrows from an outer side toward an inner side of the main body, and a needle for supplying ink to the main body is inserted into the first hole. The label in a film shape is attached to the main body. The second hole is provided at the label and overlaps the first hole in a plan view of the label. The second hole guides the needle to the first hole when the needle is inserted.

摘要： A fluid ejection head and a method of detecting the presence of fluid in an ejection chamber. The ejection head includes a semiconductor substrate having an elongate fluid supply via etched therethrough. An array of fluid ejectors is disposed adjacent to the fluid supply via, wherein the elongate fluid supply via provides fluid to the array of fluid ejectors for ejection of fluid from the ejection head. Fluid sense cells for the array of fluid ejectors are disposed at each end of the fluid supply via, wherein each of the fluid sense cells has a fluid ejector, an electrode disposed in a fluid chamber for the fluid ejector, and an electrode disposed in a fluid channel associated with a fluid chamber. A fluid detection circuit is provided in electrical communication with each of the fluid sense cells for detecting the presence or absence of fluid in the fluid chamber.

摘要： A system and method for ejecting one or more fluids from a digital dispense device. The method includes selecting a) fixed target areas and total fluid volumes for the target areas of the substrate; b) a predetermined droplet volume for the target areas; c) calculating a required number of droplets for the target areas; d) determining a maximum number of droplets per pixel based on the target areas; e) calculating a number of droplets per pass of an ejection head over the target areas; f) modifying one or more dimension of the target areas to create modified target areas; g) selecting and centering the modified spot size target areas in the target areas; and h) depositing fluids in the modified target areas while scanning the ejection head over the modified target areas.

摘要： A cartridge having a reservoir for fluid, a tower with an interior chamber, wherein the tower has a first end proximate the reservoir, a second end distal the reservoir, a port in the second end of the tower, and an interior for conducing the fluid from the reservoir. A first rib and a second rib extend along a length of the tower, in the interior of the tower. Both the first and second ribs have second ends that are substantially adjacent the second end of the tower, and the first rib has a first end that extends along the length of the tower toward the first end of the tower further than a first end of the second rib. At least one of the first and second ribs at least partially overlaps a first via within the port and is spaced apart from the first via by a gap.
