Fixing Control Circuit
The Fixing control circuit controls the temperature in the Fixing Unit. The printer uses an on-
demand Fixing method.
The figure below shows the configuration of the Fixing control circuit.

Fixing control circuit
Fixing Heater (H1): Heats the Fixing Film
Thermistor (TH1): Detects Fixing temperature (Contact type)
Thermoswitch (TP1):Prevents an abnormal temperature rise of the Fixing Heater
(Contact type)
These temperature controls in the Fixing Unit are performed by the Fixing Heater control
circuit and the Fixing Heater safety circuit according to the commands from the DC Controller.

Throughput Reduction Control
During continuous printing, the throughput is changed to reduce heat buildup on parts not in
contact with paper, to improve Fixing characteristics and reduce curling.
The throughput reduction is implemented according to the following conditions.
