A waste liquid tank includes a case. The case includes a first accommodating portion having an inlet and a first communication opening, a second accommodating portion having a second communication opening and a connecting portion connecting the first communication opening and the second communication opening, wherein a cross-sectional area of the connecting portion is less than a cross-sectional area of the first accommodating portion and is less than a cross-sectional of the second accommodating portion. The waste liquid tank includes a first absorber accommodated in the first accommodating portion, a second absorber accommodated in the second accommodating portion and a third absorber accommodated in the connecting portion. The connecting portion includes a passage defined between the third absorber and a peripheral portion of the connecting portion, the passage allowing the first accommodating portion to communicate with the second accommodating portion and for air to pass therethrough.

A print cartridge including a cartridge body, a fluid reservoir disposed within the cartridge body that receives and contains fluid, a fluid ejector chip comprising a plurality of heating elements that eject the fluid from the print cartridge, and a memory device that stores first data related to information regarding the number of times the print cartridge was remanufactured and second data related to information regarding the print yield of the print cartridge for each instance of cartridge remanufacture.

A tank includes: a wall separating a liquid storage chamber, which stores a liquid to be supplied to a liquid consuming part, from an outside; an inlet penetrating the wall; and a liquid outflow part which allows the liquid to flow to the outside of the liquid storage chamber. The wall includes a view wall, which extends upward and downward and allows a user to visually check a liquid level in the liquid storage chamber, and a bottom wall, which defines an inner bottom surface of the liquid storage chamber by being connected to the view wall. The inner bottom surface of the bottom wall includes an inclined part which extends from at least a part of the view wall to incline downward in a direction away from the view wall.

An inkjet printer includes a waste ink treatment system and a humidification chamber to separate waste ink produced by a printhead maintenance station into solid ink pigment particles and a solvent stream and use the solvent stream to maintain inkjets in the printheads of the inkjet printer in operational status. The waste ink treatment system mixes the waste ink with a metal salt to precipitate the solid ink pigment particles out of the waste ink. The solvent stream remaining after the precipitation of the pigment particles is humidified and directed to air baffles positioned on opposite sides of each printhead in every other printhead module in the process direction. A kit is provided to retroactively modify an existing inkjet printer to treat the waste ink and use the solvent stream to maintain the operational status of the inkjets in the printheads of the inkjet printer.

An inkjet printer uses ink supply containers that includes bladders for holding waste fluids produced by printhead maintenance stations. The bladders are connected serially or in parallel to the output ports of the printhead maintenance stations to store waste fluids within the bladders of the ink supply containers. As the ink supply containers are depleted of their supply ink, they are replaced and new ink supply containers having bladders within them are installed to renew the capacity of the printer to store waste fluids. In two embodiments, the need for a waste fluid reservoir is eliminated and in a third embodiment, the operational life of a waste fluid reservoir is extended. In all of these embodiments, the production of plastic waste by the printer is reduced.

There is provided a liquid container including: a pouch and a case. The pouch includes a flexible bag and a spout with a first opening. The case includes a tank to store a liquid flowed through the second opening. The spout is fitted into the case, and the bag is positioned in the tank.

An object of the present invention is to reduce the amount of solvent vapor floating around when a print head is cleaned in an inkjet recording device. In addition, an object is to reduce ink stains on a periphery of the print head. An inkjet recording device includes a main body portion and a print head. The main body portion includes an ink container that contains ink, and a solvent container that contains a solvent. The print head includes a nozzle connected to the ink container to discharge the pressurized and supplied ink, a charging electrode that charges ink particles discharged from the nozzle, a deflection electrode that deflects the ink particles charged by the charging electrode, and a gutter that collects the ink. In addition, a head mounting unit for cleaning the print head is provided. The head mounting unit is connected to a solvent vapor suction path for suctioning solvent vapor generated therearound.
