ABSTRACT:
An apparatus and method that utilize a sensor circuit and a liquid supply to control resistance of a fluid carrier of an aquatron. The resistance of the fluid carrier or charging pad is maintained by controlling the loading or concentration of liquid in the charging pad. A comparison of the fluid or liquid level in the charging pad to the desired fluid level for the charging pad triggers the addition or reduction of fluid to the charging pad to achieve the desired fluid level and thus the desired resistance. A minimum fluid carrier resistance is required to prevent loading the power supply when charging over pinholes and scratches in the imaging surface.
