ABSTRACT:
A micro-fluid ejection head and method for reducing a stagger pattern distance and improving droplet placement, on a receiving medium. The micro-fluid ejection head includes a substrate containing a plurality of ejection actuators on a device surface thereof and a fluid supply slot for providing fluid to be ejected by the micro-fluid ejection head. The ejection head also includes a flow feature component in flow communication with the fluid supply slot and configured for providing fluid ejection chambers and fluid supply channels for the fluid ejection chambers. Adjacent first and second ejection actuators in a substantially linear array of ejection actuators are each spaced a first distance from the fluid supply slot and second and third ejection actuators in the linear array of ejection actuators are each spaced a second distance from the fluid supply slot that is less than the first distance.
