Power control for a xerographic fusing apparatus

摘要

A fusing apparatus for xerographic printing includes a fuser roll with two parallel lamps, or heating elements, therein. At power-up, power is applied to each lamp in a stair-step fashion, in which incremental increases in applied power for each lamp a re staggered in time. The incremental increases are made by adding half-cycles to an alternating current applied to each lamp. <IMAGE>
