Abstract
An ink supply tank has a plurality of walls forming a cavity and a bottom wall formed with an ink outlet port. An ink absorbing member is disposed within the cavity positioned adjacent the ink outlet port. A plurality of grooves are recessed within the bottom wall and have a depth which gradually increases toward the ink outlet port. The grooves are approximately parallel to and are equally spaced apart from each other. The grooves extend along the longitudinal axis of the tank and are of the same width. A pair of grooves also extend along a transverse axis of the tank and are positioned on opposed sides of the ink outlet port and are parallel to each other. The transverse grooves have a width greater than the width of the longitudinal grooves.
