Abstract
A fusing apparatus for xerographic printing includes two lamps therein. There is applied to the first lamp a first wave set and to the second lamp a second wave set, each wave set comprising a predetermined arrangement of active half-cycles for each time period. The first wave set and second wave set are related to substantially minimize simultaneous active half-cycles in each time period.
Claims8
A method of operating a fusing apparatus such as used in printing, the fusing apparatus including a first lamp and a second lamp, comprising:
- applying to the first lamp a first wave set and applying to the second lamp a second wave set, each wave set comprising a predetermined arrangement of active half-cycles for each time period;
- and
- for each of a plurality of selected combinations of power levels for the lamps, the first wave set and second wave set being related to substantially minimize simultaneous active half-cycles in each time period.
A method of operating a fusing apparatus such as used in printing, the fusing apparatus including a first lamp and a second lamp, comprising:
- applying to the first lamp a first wave set and applying to the second lamp a second wave set, each wave set comprising a predetermined arrangement of half-cycles for each time period;
- and
- the first wave set and second wave set being related to substantially maximize interleaving of active half-cycles between the first wave set and the second wave set.
