  • Publication number: 20090268000
    Abstract: A fluid supply system for a printing device is disclosed. The fluid supply system includes an ink reservoir adapting member operatively disposed within an ink cartridge. The adapting member has an open end and an end opposed to the open end. The open end is adapted to have a filter disposed thereon. The opposed end is substantially angularly offset from the open end in a manner sufficient to substantially promote fluid and air migration toward a fluid conduit. A depth between the open end and the opposed end substantially varies along a length between two opposed sides of the adapting member. A predetermined area of the opposed end defines the fluid conduit, and the predetermined area is located at a region where the depth is substantially greatest. Further, the conduit is adapted to release fluid and air from the adapting member.
