Theory of Operation
Fusing
Toner is applied by the BTR and the Developers. The toner image is applied 
on the paper with the Fuser (Fusing Unit) by the Free Belt Nip Fusing (FBNF) 
thermal fusing system. The Heat Roll with the Heater Lamp melts the toner 
particles. Toner is fused onto the paper by the combination of heat and 
pressure.
Cleaning
A cleaning blade in the Print Cartridge scrapes off toner remaining on the 
drum surface after transfer has occurred. Then, the latent charge pattern 
remaining on the photoconductive drum is neutralized by the Erase Lamp to 
prepare the drum for the next Exposure cycle.
