Abstract: An ink tank for an ink jet printer containing an electronic memory device for storing information on the contents of the ink tank, wherein the ink tank has an elongated casing having one end adapted to be inserted into a mounting socket of the ink jet printer in an essentially horizontal direction, and the electronic memory device is configured as a button provided on a bottom side of the casing so as to engage an electric contact of the mounting socket under the weight of the ink tank.

Abstract: An ink tank including a casing having a front wall provided with a coupling, and a bag disposed in said casing and connected to said coupling, wherein the casing comprises a first shell including said front wall, and a second shell welded to the first shell.

Abstract: An ink tank for an ink jet printer which includes a casing having a bottom wall and a front wall with an opening provided therein, and a bag disposed in said casing, said bag being collapsible into a sheet-like configuration and having a top wall, a bottom wall, a front edge and a spout provided in a central region of said front edge and located at the position of said front wall opening, wherein the width (W) of the top and bottom walls of the bag, when measured in a flat, sheet-like configuration and in the direction of the front edge, is larger than the width of the casing, and the front wall opening is located near the bottom wall of the casing.

Abstract: An ink jet printing system a print head containing nozzles, a replaceable ink container, an ink supply reservoir connecting the ink container to the nozzles of the print head, and a temperature control system for controlling the temperature of the ink in the ink supply reservoir, wherein the parameters T(0); &Dgr;T/&Dgr;t, which permit a determination of the optimal operating temperature for the ink are physically encoded on the ink container to be read by the temperature control system, T(0) being the optimal operating temperature at time 0 and &Dgr;T/&Dgr;t representing the temperature change of the ink over time.
