Abstract
An ink loader enables identification of features on a solid ink stick placed on an ink stick support in the ink loader. The ink loader includes two optical sources configured to emit diffuse light toward different surfaces of the solid ink stick. Two corresponding sets of optical sensors are positioned to receive light reflected from identifying features, if present, on the solid ink stick. A controller receives signals generated by the two sets of optical sensors and identifies the ink stick with reference to the signals from the sensors.
