2-1-7 Fixing section
The fixing section consists of the parts shown in Figure 2-1-24. When paper reaches the fixing section after the transfer
process, it passes between the press roller and heat roller, which is heated by fixing heaters M or S (FH-M or FH-S).
Pressure is applied by the fixing unit pressure springs so that the toner on the paper is melted, fused and fixed onto the
paper. The heat roller is heated by fixing heaters M or S (FH-M or FH-S) inside it; its surface temperature is detected by
the fixing unit thermistor 1 and 2 (FTH1,2), and is regulated by the fixing heaters turning on and off.
If the fixing section becomes abnormally hot, fixing unit thermostat (FTS) operates shutting the power to the fixing
heaters off. When the fixing process is completed, the paper is separated from the heat roller by its separation claws and
is conveyed from the copier to eject and switchback section.
