Abstract
Each ink stick of a set of ink sticks for a phase change ink jet printer has formed on the top of the ink stick a three dimensional visually recognizable symbol. At least a portion of the visually recognizable symbol on each of the ink sticks is different, so that the printer user can distinguish which ink stick is intended for each of the ink feed channels of the ink jet printer.
