Solid ink stick having identical identifying features on a plurality of edges

摘要

A solid ink stick (100) enables identification of the ink stick in a variety of different orientations, while preventing the ink stick from being inserted into an ink loader in an orientation in which the ink stick cannot be identified. The ink stick includes two polygon end surfaces (160,164) opposite one another. Each edge of the end surfaces has a first and a second identifier, which are identical to one another to enable the ink stick to be inserted into an ink loader without regard to the orientation of the edges.
