Abstract
An apparatus includes a developer to receive a toner, and an actuator moveable between different positions. An electrical switch is responsive to an input stimulus from the actuator to control a voltage that enables or disrupts a transfer of the toner from the developer to a photoreceptor, where the electrical switch when in a first state sets the voltage at a first level to enable the transfer of the toner from the developer to the photoreceptor, and the electrical switch when in a second state sets the voltage at a second level to disrupt the transfer of the toner from the developer to the photoreceptor.
