Abstract:
A liquid circulation device includes a liquid discharge head, a circulation channel through which a liquid is circulated via the liquid discharge head, a first liquid feed pump to supply the liquid to the liquid discharge head in a circulation direction, a second liquid feed pump to collect the liquid from the liquid discharge head in the circulation direction, a filter disposed in the circulation channel upstream from the first liquid feed pump and downstream from the second liquid feed pump in the circulation direction, and a decompression-side reverse channel to bypass the second liquid feed pump. One end of the decompression-side reverse channel is connected to the circulation channel upstream from the second liquid feed pump, and another end of the decompression-side reverse channel is connected to the circulation channel downstream from the filter in the circulation direction.

Claim (Index 7):
The liquid circulation device according to  claim 1 , further comprising:\n a plurality of liquid discharge heads; and a first manifold communicating with a supply port of each of the plurality of liquid discharge heads; a second manifold communicating with a discharge port of each of the plurality of liquid discharge heads; a first sub tank disposed between the first manifold and the first liquid feed pump, the liquid supplied to the first manifold from the first sub tank by the first liquid feed pump; and a second sub tank disposed between the second manifold and the second liquid feed pump, the liquid collected from the second manifold to the second sub tank by the second liquid feed pump.
