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.
