Patent ID: 8042927

Claim:
An ink storage and supply assembly comprising at least one ink reservoir positioned in an imaging device, the at least one ink reservoir being formed with a thermally conductive material configured to have an opening through which liquid ink is received into the at least one reservoir and a chamber configured to hold a quantity of the liquid ink received through the opening, the at least one ink reservoir being configured to communicate the liquid ink held in the chamber to at least one printhead of the imaging device; and a housing at least partially enclosing the at least one ink reservoir, the housing including a top wall positioned above the at least one ink reservoir, a bottom wall positioned below the at least one ink reservoir, and a plurality of side walls extending vertically between the top wall and the bottom wall of the housing, the plurality of side walls being formed of mica panels and being spaced from the thermally conductive material of the at least one reservoir to form a first air gap between each of the side walls and the at least one reservoir, at least one of the side walls including an inner wall that forms the first air gap with the at least one reservoir and an outer wall that is spaced from the inner wall to form a second air gap between the inner wall and the outer wall, the top wall and the bottom wall of the housing being formed with a thermally resistant material, the top wall and the bottom wall of the housing including locating grooves, each locating groove being configured to receive an edge of one side wall in the plurality of side walls to position the side walls about the at least one reservoir to form the first air gap and to form the second air gap between the inner wall and the outer wall of the at least one side wall.
