Patent ID: 8042895

Claim:
A method of using an ink reservoir of an imaging device, the method comprising: measuring an ink conductivity of an ink volume in an ink reservoir of an imaging device, the ink reservoir being configured to receive ink from an ink supply and to deliver the received ink to at least one printhead of the imaging device; comparing the measured ink conductivity to a predetermined ink conductivity operational range; in response to the measured ink conductivity being below or exceeding the predetermined ink conductivity operational range, performing a flush routine that 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; comparing the detected ink conductivity to the predetermined ink conductivity operational range; in response to the measured ink conductivity being within the predetermined ink conductivity operational range after a flush routine has been performed, returning the imaging device to a normal operating mode.
