Patent ID: 8837967

Claim:
A method for determining and applying a transfer voltage for use in an imaging apparatus having a member bearing a toner image, a transfer roller positioned adjacent to the member forming a transfer nip therewith, the method comprising: detecting a condition associated with an imaging apparatus; determining a servo voltage to be applied to the transfer roller during a transfer servo operation, the determining being based on the condition detected, the servo voltage being determined prior to a voltage being applied to the transfer roller during the transfer servo operation; applying the servo voltage to the transfer roller and measuring a servo current in the transfer nip; determining a transfer voltage based on the servo current; applying the transfer voltage to the transfer roller during an image transfer operation by the imaging apparatus; measuring transfer current in the transfer nip during one or more inter-page gaps of the image transfer operation; and adjusting the transfer voltage based upon the measured transfer current to create an adjusted transfer voltage.
