An occlusion for use in a peristaltic pump includes independently movable occlusion fingers. The fingers are integrally formed as a single unitary body.

Peristaltic pump

An airflow assembly for a fluid-ejection mechanism of one embodiment of the invention is disclosed that includes at least one first surface and at least one second surface. The at least one first surface is to at least substantially cause airflow to be deflected around the fluid-ejection mechanism while the fluid-ejection mechanism is moving. The at least one second surface is at least substantially flush with a front surface of the fluid-ejection mechanism, to create airflow drag over the front surface of the fluid-ejection mechanism while the fluid-ejection mechanism is moving.
