F32-02 An error for FIXFAN1_EM signal is
detected when 2 seconds have
passed since FM8 (main unit cool-
ing /2) has turned ON. The error
does not clear after 2 seconds from
the OFF/ON operation.
The machine body
stops immediately

F34-02 The output voltage of TH1 (fixing
temperature /1) and TH2 (fixing
temperature /2) is detected as
abnormally high at the comparator
circuit (more than 228
°
C).
Low fixing
temperature
abnormality
F35-01 TH1 (fixing temperature /1) has not
reached the predefined tempera-
ture when the specified time has
passed since the fixing ON control
has been processed after SW2
(sub power) is turned on.

less than 120
°
C for 5 consecutive
times in 1 second cycle while the
fixing ON control is processed after
warm-up operation is complete.
F35-03 The output voltage of TH1 (fixing
temperature /1) is detected as
abnormality low at the comparator
circuit (less than -6
°
C).
