ABSTRACT:
A system, method, and apparatus for adjusting dry ink concentration in a developing station (30) of a printer is disclosed. The adjustment is performed by calculating the thermal drift of a dry ink monitor (40) and applying the result as a compensating factor in calculations in a software algorithm. The dry ink monitor (40) has a sensing port (42) in contact with a dry ink concentration and is connected to a dry ink monitor interface board (10) that houses a temperature sensor (20). The monitor interface board (10) is positioned in proximity to the dry ink monitor (40) to enable the temperature sensor (20) to measure a temperature of the dry ink concentration. The software algorithm is used to adjust the dry ink concentration based on a slope coefficient calculated by the printer based on outputs from the dry ink monitor (40) and the dry ink monitor interface board (10).
