Temperature
Signal
TS Maintains the set temperature of approximately 150°C for fusing by turning on/off
the thyristor.
TA Used as a reference temperature (approximately 185°C) to identify that it is exces-
sively hot inside the fuser. When it reaches 185°C, the relay RY turns off, the power
to the heat lamp is shut down, and the printer stops.
TPS Limits temperature through the use of a temperature fuse which shuts down the
power to the heat lamp if the temperature control circuit breaks down. When the
temperature fuse is blown, the printer will stop.
Error
H0 When THERR signal is input, the operator panel displays "H0", and the printer
stops.
H2 If the temperature of the fuser will not reach to the required point "T1" after a given
time has elapsed, the operator panel displays "H2", and the printer stops.
H3 If the "Heater On" signal continues after a given period of time, the operator panel
displays "H3", and the printer stops.
H4 If the temperature within the fuser becomes unusually hot, and when ACOFF signal
is input, the operator panel displays "H4", and the printer stops.
