Product Technical Overview
Launch Issue
Fuser Temperature Control
The heat roll temperature is monitored by the fuser non-contact sensor in the center of the heat
roll and a soft-touch thermistor at the rear end of the heat roll. Each sensor measures the tem
-
perature in its region then provides temperature information to the drive PWB. Figure 7.
The drive PWB logic uses the inputs from the sensors to control the fusing temperature by
switching the heat rods on and off as required, refer to BSD 10.1 Fusing Heat Control (1 of 2).
The thermostats, located near the center and the front of the heat roll, provide over tempera-
ture protection. When the surface temperature of the heat roll exceeds a predetermined value,
the thermostat opens, de-energizing the fuser relay and cutting off the current to the heat rods,
refer to BSD 10.1 Fusing Heat Control (1 of 2), Figure 7.

Fuser Cooling
The fuser fan, PL 40.15 Item 4, exhausts heated air from the fuser area via the ducting. Refer
to Figure 8 and Figure 9.
