Abstract

In some examples a printing system includes purging manifolds. The printing system includes a fluid ejection device to dispense a fluid and a first reservoir to house a fluid. The system further includes a purging manifold to fluidically couple to the fluid ejection device, and the purging manifold to fluidically couple to the first reservoir. The purging manifold includes a second reservoir. The purging manifold further includes a supply port; a fluid inlet port; and a purging outlet port. The purging outlet port is disposed above the supply port to convey fluid to the first reservoir. The printing system also includes a fluid interface connector to fluidically connect to the supply port and fluidically connect to the fluid ejection device.
