Abstract

An ink stick for use in a solid ink feed system of a phase change ink jet printer includes at least first and second three dimensional ink stick body portions. Each ink stick body portion includes a perimeter section that is substantially the same as a corresponding section of a keyed insertion opening in the solid ink feed system. Each ink stick body portion also includes a joint perimeter section that is the complement of the joint perimeter section of the other ink stick body portion, so that the first and second ink stick body portions fit together.

Claims

1. An ink stick for use in a solid ink feed system of a phase change ink jet printer, wherein the solid ink feed system includes at least one insertion opening having a keyed perimeter shape, the ink stick comprising:

2. The ink stick of claim 1, wherein no section of the second ink stick perimeter is substantially the same as the first section of the keyed perimeter shape of the insertion opening.

3. The ink stick of claim 2, wherein no section of the first ink stick perimeter is substantially the same as the second section of the keyed perimeter shape of the insertion opening.

4. An ink stick for use in a solid ink feed system of a phase change ink jet printer, the ink stick comprising:

5. The ink stick of claim 1, wherein the ink stick perimeter is identified as the ink stick is viewed from above the ink stick.

6. The ink stick of claim 4, wherein the second portion of the key shape is not formed in the first ink stick body portion.

7. The ink stick of claim 6, wherein the first portion of the key shape is not formed in the second ink stick body portion.

8. A method of inserting an ink stick through an insertion opening having an opening shape into a solid ink feed system of a phase change ink jet printer, the method comprising:

9. The method of claim 8, wherein the inserting step comprises inserting the first and second ink stick portions through an opening having shaped segments substantially similar to the first and second perimeter segments.

10. The method of claim 8, wherein placing the first and second ink stick portions adjacent one another comprises placing the first and second ink stick portions in substantially the same plane.
