摘要： A droplet ejection device includes a liquid ejection head, a supply flow path, a supply pump, and a supply flow path pressurizer. The supply flow path supplies the liquid to the head and for which a first depressurization threshold is specified in advance. The supply pump sucks the liquid, pressurizes the sucked liquid and supplies the sucked liquid to the head via the supply flow path, and keeps a pressure of liquid in the supply flow path near to a predetermined supply flow path target pressure. The supply flow path pressurizer pressurizes the pressure of liquid in the supply flow path if the pressure of liquid in the supply flow path falls to less than or equal to the first depressurization threshold.

摘要： An ink cartridge is provided with an ink run-out checking section having an air-curable curing agent. When the ink contained in the ink cartridge is reduced to expose the checking section to air, the curing agent is cured. A movable pushing member pushes a deformable film of the checking section. If the curing agent is uncured, the movable pushing member stops at a position where the deformable film is deformed into the curing agent. If the curing agent is cured, the deformable film cannot deform, so the movable pushing member stops at a position just in contact with the deformable film. Based on the position of the movable pushing member, a controller judges whether the ink remains or not, as well as whether the ink cartridge is mounted or not.

摘要： A case body of an ink cartridge has a recording ink storage chamber containing a recording ink and a waste-ink storage chamber containing an ink coagulant. The recording ink is supplied to a recording head of an ink jet recording apparatus. A head cleaning unit collects waste-ink from the recording head and feeds it to the waste-ink storage chamber. A heater heats the waste-ink and the ink coagulant in the waste-ink storage chamber, so that the ink coagulant melts and mixes with the waste-ink. The mixture of the ink coagulant and the waste-ink is cooled and solidified into gel. The gelled mixture of the waste-ink and the ink coagulant can be easily taken out of the waste-ink storage chamber by heating to liquefy it again, facilitating recycling the case body.

摘要： A method of forming a high-quality image on an elongated recording medium, such as a roll of paper sheet. When an image includes a character which stretches between two print regions, a blank line portion of the image is detected. When image forming operation is performed for forming a portion of the image up to the blank line, sheet feed operations are performed. Then, image forming operation for a remaining portion of the image is performed. Because the sheet feed operation will not be performed in the middle of printing of such image, undesirable broken line or gap will not be formed on the printed image.
