Fuser section

The fuser section consists of the parts shown in figure. When paper reaches the fuser section after the transfer process,
it passes between the press roller and heat roller, which is heated by fuser heaters M or S (FH-M or FH-S). Pressure is
applied by the fuser unit pressure springs so that the toner on the paper is melted, fused and fixed onto the paper. The
heat roller is heated by fuser heaters M or S (FH-M or FH-S) inside it; its surface temperature is detected by the fuser ther-
mistor (FTH) and is regulated by the fuser heaters turning on and off.
If the fuser section becomes abnormally hot, fuser thermostat (FTS) operates shutting the power to the fuser heaters off.
When the fuser process is completed, the paper is separated from the heat roller by its separation claws and is conveyed
from the copier to exit and switchback section.
