Abstract
A fuser assembly and associated method for an electrophotographic machine heats a first fuser roll with a first heating device. A second heating device heats a second fuser roll. It is determined whether a first temperature of the first fuser roll is below a first target temperature. It is also determined whether a second temperature of the second fluser roll is below a second target temperature. If both the first temperature is below the first target temperature and the second temperature is below the second target temperature, the first heating device is operated during a first time period and operation of the second heating device is inhibited throughout the first time period.
