In an ink supply system, an ink tank is connected with an inlet flow channel that is connected with a connection flow channel that is connected with an upstream flow channel, and the upstream flow channel is connected with an ink head. The ink head and the connection flow channel are connected with each other by a downstream flow channel. An upstream pump and an upstream damper are provided in the upstream flow channel, and a downstream pump and a downstream damper are provided in the downstream flow channel. A controller controls the upstream pump and the downstream pump.

Ink supply system and inkjet printer

An air trap unit includes an air trap container that stores ink, a flow inlet provided in the air trap container and allowing the ink to flow into the air trap container, a flow outlet provided in the air trap container and allowing the ink in the air trap container to flow out, and an inclination mechanism that inclines the air trap container such that the air trap container is put into one of a first state and a second state, the first state being a state where the air trap container is inclined such that the flow inlet is at a level higher than, or equal to, that of the flow outlet, and the second state being a state where the air trap container is inclined such that the flow outlet is at a level higher than that of the flow inlet.

Air trap unit, ink supply system, and inkjet printer

An ink cartridge of an inkjet printer includes a support holding an ink container so that a longitudinal direction of a main body of the ink container extends along a sub-scanning direction of the inkjet printer, and supporting a portion of the main body that is perpendicular or substantially perpendicular to a thickness direction of the main body such that the main body is supported horizontally. A central portion of the support is lower in height than a left portion and a right portion thereof with respect to a main scanning direction of the inkjet printer.

Inkjet recording apparatus and ink container

A liquid supply system includes a liquid supply source, an injection head, a damper in communication with the injection head, a liquid supply path including an end in communication with the liquid supply source and another end in communication with the damper, a liquid supply device supplying the liquid from the liquid supply source toward the damper, a pressure control valve provided between the liquid supply source and the liquid supply device, and a controller controlling the liquid supply device to be actuated or to be stopped. The pressure control valve closes the liquid supply path while the liquid supply device stopped.
