Hewlett Packard Fusers Lexmark Fuser Assemblies Okidata Fusers Fusers are the final stage of the printing process where the toner is "fused" to the media. In the range of 180 degrees centigrade, the toner particles will melt and fuse or melt into the paper fibers or media. The fuser assembly consists of a heat roller and a pressure roller that the paper passes through. The heat roller has a proprietary coating which allows the toner to be released and not transferred to the paper passing through on the next rotation. The lower roller is used to apply even pressure as the media passes between the two rollers. Should either of these rollers become damaged or compromised - warped, torn coating, labels or transparencies stuck to the upper roller, the fuser should be replaced.
