Abstract
An imaging system includes a transfer roller having a surface to transfer a toner image onto a print medium during a printing operation of the imaging system, a conductive device to contact the surface of the transfer roller, a power source electrically connected to the conductive device, a resistance measurement device, and a controller. The transfer roller rotates according to a printing speed of the printing operation. The power source supplies a bias to the transfer roller through the conductive device during the printing operation. The resistance measurement device measures an electrical resistance of the print medium. The controller reduces the printing speed based on the electrical resistance measured by the resistance measurement device.
