摘要：

A fluid ejection apparatus (20, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320, 1420, 1490, 1720, 1820) and method eject a droplet of fluid using a drop generator (46, 246, 1546) receiving fluid from a passage (44, 244, 1344, 1444, 1494, 1544, 1744) having an inlet (54, 254, 1554) adjacent a fluid slot (40, 240, 1540) and an outlet (56, 256, 1556) spaced from the inlet (54, 254, 1554) and adjacent the fluid slot (40, 240, 1540). Fluid is drawn through a filter (50, 250, 650, 1550) with a pump (48, 248, 1548) within the passage (44, 244, 1344, 1444, 1494, 1544, 1744) that pumps the fluid towards the inlet (54, 254, 1554) to the drop generator (46, 246, 1546).
