ABSTRACT:
A method of operating an electrophotographic printer and particularly the fuser thereof, includes preheating a heated roller of the fuser to a preheat temperature greater than the maximum target temperature for fusing, but less than the maximum temperature of a temperature range for proper fusing. During prolonged standby, the heated roller is heated to a standby temperature greater than the maximum target temperature, but less than the maximum temperature of the temperature range for proper fusing.
