Abstract
A system for reading a coded marker of an ink stick has been developed. The system includes an optical detector that detects light reflected from different areas of the generates signals in response to detecting light having at least two signal strengths that is reflected from different areas of the coded marker. A controller processes the signals from the optical detector to identify a code word encoded into the coded marker of the ink stick.
