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). |

1. A fluid ejection apparatus (20, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320, 1420, 1490, 1720, 1820) comprising:
a fluid slot (40, 240, 1540); a passage (44, 244, 1344, 1444, 1494, 1544, 1744) having an inlet (54, 254, 1554) connected to the fluid slot (40, 240, 1540) and an outlet (56, 256, 1556) spaced from the inlet (54, 254, 1554) and connected to the fluid slot (40, 240, 1540); a drop generator (46, 246, 1546) along the passage (44, 244, 1344, 1444, 1494, 1544, 1744); a fluid circulation pump (48, 248, 1548) between the drop generator (46, 246, 1546) and the inlet (54, 254, 1554); and a filter (50, 250, 650, 1550) across the passage (44, 244, 1344, 1444, 1494, 1544, 1744) between the fluid slot (40, 240, 1540) and the fluid circulation pump (48, 248, 1548). |
