Description
The main thermistor detected less
I
than 105°C for 200 ms 1 sec after it
has detected 90°C.
The main thermistor (TH1) detected
I
less than 120°C for 200 ms 1 sec after
it has detected 105°C.
The main thermistor detected less
I
than 120°C for 200 ms after it has de-
tected 105°C.
The main thermistor (TH1) detects
I
less than 135°C for 200 ms 1 sec after
it has detected 120°C.
The main thermistor (TH1) detects
I
less than 150°C for 200 ms 1 sec after
it has detected 135°C.
The main thermistor (TH1) detects
I
less than 150°C for 200 ms after it has
detected 150°C.
The sub thermistor (TH2) detects less
I
than 150°C for 200 ms after it has de-
tected 150°C.
The output of the fixing film sensor
I
continues to be '1' or '0' for 2.1 sec or
more.
The displacement is not corrected af-
I
ter executing film recovery mode
which turns on when the main power
is tuned off and on in response to
'E007'.
The value is outside a specific range,
I
and the main motor does not lock for
3 sec.
A check is made immediately before
I
the counter turns on and off. (Normal,
if the counter drive signal is '0' when
the counter turns on.)
