Document Type and Number:
Japanese Patent JP2011521806
Kind Code:
A
Abstract:
Drop-on-demand inkjet printing device (10) comprising at least one through-flow print head (20), the through-flow print head (20) having one or more nozzles (22) for ejecting a drop of fluid onto a substrate to be printed, and a fluid circulation system for feeding and circulating fluid through the print head, said fluid circulation system comprising
- a main reservoir (30) for containing an amount of fluid,
- a supply buffer tank (38) for receiving fluid from the main reservoir (30) and supplying fluid to the through-flow print head (20),
- a return manifold (64) for receiving fluid from the through-flow print head (20) and returning fluid to the main reservoir (30),
wherein the main reservoir (30) is connected to the supply buffer tank (38) via a feed conduit (40) provided with a pump means (42) for directing fluid from the main reservoir (30) to the supply buffer tank (38), wherein the supply buffer tank (38) is in fluid communication with the one or more nozzles (22) of the through-flow print head (20) via a nozzle supply conduit (52), the one or more nozzles (22) being in fluid communication with the return manifold (38) via a nozzle return conduit (62), wherein the return manifold (64) is connected to the main reservoir (30) via a discharge conduit (68),
wherein the main reservoir (30) and the supply buffer tank (38) are arranged in height with respect to the one or more nozzles (22) such that during operation a back pressure is established at the one or more nozzles (22) and fluid flows from the supply buffer tank (38) through the through-flow print head (22) to the return manifold (64) and then back into the main reservoir (30),
wherein the supply buffer tank (38) is provided with a lockable conduit (56) connecting the supply buffer tank (38) to the main reservoir (30).
