ABSTRACT:
A method for restoring ink conductivity of ink in an ink reservoir comprises detecting an ink conductivity of an ink volume in an ink reservoir, and comparing the detected ink conductivity to a predetermined ink conductivity operational range. A flush routine is performed in response to the measured ink conductivity being outside of the predetermined ink conductivity operational range. The flush routine includes: disabling ink supply operations to the ink reservoir; emptying the ink reservoir of ink; refilling the ink reservoir with ink; measuring an ink conductivity of an ink volume in the refilled ink reservoir; and comparing the detected ink conductivity to the predetermined ink conductivity operational range. The imaging device is returned to a normal operating mode in response to the measured ink conductivity being within the predetermined ink conductivity operational range after a flush routine has been performed.
