ABSTRACT:
An ink cartridge with ink level indication for containing dispensable ink is disclosed. The ink cartridge includes a cartridge body and a reservoir for receiving and storing ink within the cartridge body. The reservoir is filled with a porous material member. A window is supported by the cartridge body to be disposed adjacent the porous material member. The window interacts with the porous material member to define porous material member portions of predetermined increasing capillarities. Each portion is able to retain ink therein for viewing through the window depending on its capillarity and the amount of ink in the reservoir to thereby provide an overall indication of the amount of ink in the print cartridge.
