Abstract
A printer comprising an electrical load, a control system and an electrical circuit to switchably connect the electrical load to a first phase and a second phase of a polyphase power supply. The control system monitors a first electrical current drawn by the printer on the first phase and a second electrical current drawn by the printer on the second phase. When a difference between the first electrical current and the second electrical current satisfies a threshold condition, the control system controls the electrical circuit to disconnect the electrical load from the first phase and connect the electrical load to the second phase.
