F35-5 Low fixing temperature abnormal-
ity (L3 burnt out)
In other than warming up, the
TH2 (Fixing temperature sensor/
2) elapses for more than the
specified period of time in a tem-
perature below 329°F (7145)/
320°F (except the 7145).
The main
body stops
immediately,
and the RL1
(Main) turn
OFF. Accep-
tance of all
keys is dis-
abled.

WARNING
• When F34-
∗∗
, F35-
∗∗
or
F36-
∗∗
(fixing tempera-
ture related abnormality)
occurs, be sure to repair a
defective part before set-
ting the 25 DIPSW 3-1 to 0.
If the 25 DIPSW 3-1 is set
to 0 without repairing a
defective part, this may
cause a fire.
F35-6 TH2 (Fxing temperature sensor/
2) low temperature abnormality
• In warming up, when the tem-
perature detected by the TH2
at the start of turning on elec-
tricity to the L3 (Fixing heater
lamp /2) is below 320°F
(7145)/302°F (except the
7145), the difference between
the TH2 temperature at the
start of turning on electricity to
the L3 and the TH2 tempera-
ture after the elapse of the
specified period of time does
not reach the specified value.
• When the temperature
detected by the TH2 at the
start of turning on electricity to
the L3 (Fixing heater lamp/2)
is above 320°F (7145)/302°F
(except the 7145), the TH2
temperature does not reach
the warming-up completion
temperature in the specified
period of time after the start of
turning on electricity to the L3.
F35-7 Fixing heat roller wrapping jam
failure (TH1)
While in copying, the TH1 (Fixing
temperature sensor/1) detects a
condition in which the tempera-
ture is lower than the specified
one as compared with the tem-
perature taken the specified
period of time previously.
