Abstract:
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.

International Classification:
B41J 2/135
US Classification:
347 44, 347 37, 347 67
Abstract:
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.
