Abstract
An ink stick for use in a phase change ink imaging device is provided. The ink stick comprises a three dimensional ink stick body having an exterior surface. The ink stick includes one or more coded markers formed in the exterior surface from a leading end to a trailing end of the ink stick body parallel to a feed direction of the ink loader, each coded marker including a coded pattern of indicia for being optically read as the coded marker passes a sensor in the feed channel. The coded pattern of indicia may include areas of varying widths and/or varying reflective properties for generating a coded signal pattern indicating variable control/attribute information to a control system of an imaging device.
