APARELHO PARA MANIPULAR A TRANSFERENCIA DE MATERIAL FUSIVEL E APARELHO PARA LIGAR O MATERIAL FUSIVEL COM UMA AREA DE IMAGEM DISCRETA NA SUPERFICIE DE UM SUBSTRATO

摘要

Image defining toner is transferred to cut sheets and fused at one of two fuser stations (21,22). One station (22) is positioned to fuse the image on one side when duplex copying or printing is selected. The other fuser station (21) performs fusing when simplex copying is selected but fuses the second side copy for duplexing. When flash lamps are employed for the fuser station, the lamps are composed of multiple bays with a single power source coupled to each bay in sequence so that the power source size need only accommodate the power level demand of one bay. The time between trigger pulses is extended by commencing fusing with an intermediate bay followed by the initial bay and then the final bay as the image area requiring fusing passes along its path in proximity to the faces of the flash lamp bays.
