Abstract: Technology enabling stably attaching a cartridge having a fluid supply port and a waste fluid inlet to a fluid ejection device. The cartridge has a bottom wall with a fluid supply port for supplying fluid to the fluid ejection device, and a waste fluid inlet for recovering waste fluid from the fluid ejection device, a first side wall having a first contact part capable of contacting a first fastening member of the cartridge holder when the cartridge is installed in the cartridge holder, and a second side wall having a second contact part capable of contacting a second fastening member of the cartridge holder when the cartridge is installed in the cartridge holder. When looking at the cartridge from the bottom wall side, an imaginary first line passing through the first contact part and the second contact part passes between the fluid supply port and the waste fluid inlet.

Abstract: Technology suppressing installation of a cartridge for supplying fluid and recovering waste fluid in a wrong orientation to a fluid ejection device is provided. The cartridge has a box-shaped case. The cartridge includes a fluid pack that stores a fluid and that is disposed in the case and a waste fluid retainer that is disposed beside the fluid pack inside the case. The waste fluid retainer is configured to hold waste fluid introduced to the case from the fluid ejection device. At least one corner of a side of the case on the side on which the fluid pack is disposed is beveled.

Abstract: An ink cartridge has an ink pack that holds ink and a case that holds the ink pack. The case has a case body forming an ink pack storage space R, and a cover that is removably attached to the case body. An ink supply opening is formed in the front wall of the case body, and a body-side pedestal protruding from the interior of the case body toward the cover inside the case is formed at the opposite end as the ink supply opening. When the cover is attached to the case with an ink pack inside, the back end part of the ink pack is held between a cover-side pedestal protruding from the interior of the cover and the body-side pedestal. The back side of the body-side pedestal forms an exterior recess on the case that can be used as a fingerhold.

Abstract: A maintenance unit 20 of a printer 1 has a waste ink recovery tank 24 that recovers waste ink. First and second mixing tubes 22A and 22B connect to the waste ink recovery tank 24. One mixing tube 22A branches into a tube BK and a tube Y, and the second mixing tube 22B branches into a tube C and a tube M. Black ink BK and yellow ink Y are merged and mixed in first mixing tube 22A before entering the waste ink recovery tank 24. The mixed inks from both mixing tubes then mix and flow together through a flow path 33 in the waste ink recovery tank 24. As a result, the chance of the ink inlets to the waste ink recovery tank becoming clogged by ink that has increased in viscosity can be reduced.
