Abstract: A solid ink stick identification system enables accurate and efficient identification of solid ink sticks in a solid ink imaging device. The solid ink identification system includes an actuator configured to move one of an optical source and an optical sensor between a plurality of predetermined positions. The optical source emits light toward a face of the ink stick, and the optical sensor generates signals corresponding to an amount of reflected light received. A controller identifies features on the solid ink stick based on the signals as the one of the optical source and optical sensor is moved between the plurality of predetermined positions.

Abstract: A solid ink stick enables identification of the ink stick in a variety of different orientations, while preventing the ink stick from being inserted into an ink loader in an orientation in which the ink stick cannot be identified. The ink stick includes two polygon end surfaces opposite one another. Each edge of the end surfaces has a first and a second identifier, which are identical to one another to enable the ink stick to be inserted into an ink loader without regard to the orientation of the edges.

Abstract: A variable resistive heater element enables current to flow through a first resistive heater element and a second resistive heater element based on the temperature of the variable resistive heater element. Current flows through the first resistive heater element, and is restricted through the second resistive heater element, when the variable resistive heater element is less than a predetermined temperature. Current flows through the first and second resistive heater elements when the variable resistive heater element is at or greater than a predetermined temperature.

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.

Abstract: An ink jet printer includes an ink supply system and a printhead with nozzles for ejecting ink drops. The printer determines the average size of the ejected ink drops by comparing the number of ink drops ejected in a predetermined time with the quantity of ink delivered through the printers ink supply system during that time. If the determined average ink drop size does not match predetermined ink drop size criteria, the printer adjusts the activation signals for the ink jet nozzles to alter the ink drop size. A solid ink printer determines the quantity of ink delivered through the ink supply system by counting the number of whole or partial ink sticks that pass a predetermined point in the ink supply system. The counter detects a sensing element formed on an external surface of the ink stick. Exemplary detectors include a mechanical arm, or a thermistor to detect a change in the printer melt plate temperature due to a change in the cross sectional area of an ink stick being melted.
