Abstract
When powering up a xerographic fusing apparatus with two parallel lamps, power is applied to each lamp in a stair-step fashion, in which incremental increases in applied power for each lamp are staggered in time. This feature contributes to desirable anti-flicker effects of the whole apparatus.
