摘要： Disclosed is a system for regulating airflow velocity in a print gap region of a micro-fluid ejection device. The system includes a carrier member configured to carry an ejection head therewithin; a nozzle array configured at a bottom portion of the ejection head; and a channel member extending from a top portion of the carrier member and along a depth of the carrier member up to the bottom portion of the ejection head. Also, the channel member extends along at least a width of the nozzle array. Additionally, the channel member is configured to receive a flow of air through a slot configured at the top portion of the carrier member and to direct the flow of air from the top portion of the carrier member towards the bottom portion of the ejection head. Further disclosed is another system for regulating airflow velocity in a print gap region.

摘要： A micro-fluid ejection device defines a print gap from an ejection head to a print media. An ejection zone of the head ejects fluid across the print gap during use. At least one wind baffle adjacent the ejection zone modifies airflow in the print gap as the head scans. In various designs, multiple wind baffles reside on either sides of the ejection zone to provide a cascading airflow effect from one wind baffle to the next. Baffle shapes, spacing and locations define multiple embodiments.

摘要： A consumable supply item for an imaging device holds an initial or refillable volume of pigmented ink. Its housing defines an interior and exterior. The interior retains the ink and an exit port supplies it to an imaging device. Users orient the housing to deplete the ink in a direction of gravity toward a bottom surface of the interior en route to the exit port. The ink passes through a mixing chamber having inlet ports arranged to restrict to multiple different heights the entrance of the volume of ink from the interior. As ink draws from various heights into the chamber, sediments in the pigment mix together. The design overcomes settling. It also avoids mechanical stirring and other complex mixing techniques. Further embodiments include chamber shapes, configuration of inlet ports, and construction of the supply item, to name a few.

摘要： Micro-fluid ejection heads and methods for extending the life of micro-fluid ejection heads. One such micro-fluid ejection head includes a substrate having a plurality of thermal ejection actuators. Each of the thermal ejection actuators has a resistive layer and a protective layer thereon. A flow feature member is adjacent the substrate and defines a fluid feed channel, a fluid chamber associated with at least one of the actuators and in flow communication with the fluid feed channel, and a nozzle. The nozzle is offset to a side of the chamber opposite the feed channel. A polymeric layer having a degradation temperature of less than about 400° C. overlaps a portion of the at least one actuator associated with the fluid chamber and positioned less than about five microns from at least an edge of the at least one actuator opposite the fluid feed channel.
