As part of its protective mechanism, the machine checks for the following er-

ror conditions:
Description
In the course of start-up control, the thermistor reading
is less than 30 deg C 1 sec after the start of power supply
or is less than 70 deg C 2 sec after the start of power
supply; the machine will identify an error condition if
any of the foregoing continues for 200 msec or more.
The thermistor detects 235 deg C for 200 msec or more
continuously.
A hardware circuit detects overheating in relation to the
thermistor (main or sub).
The thermistor detects 295 deg C or more for 200 msec
or more continuously.
In the course of start-up control, the thermistor detects a
temperature lower then 115 deg C for 200 msec
continuously after it has detected 100 deg C; the
thermistor detects a temperature less than 150 deg C for
200 msec or more continuously after it has detected 140
deg C; or, the thermistor detects a temperature lower
than 165 deg C for 20 msec or more continuously 1 sec
after it has detected 160 deg C.
In the course of normal temperature control, the
thermistor detects a temperature lower than 140 deg C
for 20 msec or more continuously.
The reading of the main thermistor is in excess of 100
deg C with the fixing motor in a locked state and, in
addition, the machine fails to detect the marker signal
for 6 sec.
During operation, the machine detects an overload
condition continuously for 3 sec or more.
