C
When the fixing temperature reaches 175
°
C/347
°
F, the copier enters primary
stabilization. 50 ms later the cleaning lamp (CL) and developing bias (DB REM) turn
on and primary stabilization starts.
D
200 ms after the cleaning lamp (CL) turns on, the drive motor (DM) turns on.
E
270 ms after the drive motor (DM) turns on, the paper conveying motor (PCM),
paper conveying fan motor (PCFM) and image formation section fan motor (IFFM)
turn on and cooling fan motor 1 (CFM1) rotates at full speed.
F
When the fixing temperature reaches 180
°
C/356
°
F (42 ppm) or 190
°
C/374
°
F (52 ppm),
the copier enters secondary stabilization. Fixing heater M (H1) is turned on and off
to keep the fixing temperature at 180
°
C/356
°
F (42 ppm) or 190

and aging starts.
G
116 s (42 ppm) or 176 s (52 ppm) after the power relay (PRY) turns on or 60 s (42
ppm) or 120 s (52 ppm) after the copier enters secondary stabilization (whichever
event occurs first), copying is enables.
H
3 s after copying is enabled, the drive motor (DM), paper conveying motor (PCM)
and image formation section fan motor (IFFM) turn off, and aging ends. Cooling fan
motor 1 (CFM1) rotates at half speed.
I
600 ms after aging ends, the cleaning lamp (CL), developing bias (DB REM) and
paper conveying fan motor (PCFM) turn off.
• Fixing control temperature correction
Depending on the ambient temperature, the fixing control temperature is corrected as
follows.
Table 1-3-1
Fixing heater M or S (H1 or H2) is turned on for 5 s from the start of the copying
operation so that the fixing control temperature becomes 190
°
C/374
°
F (10
°
C/18
°
F
higher for 42 ppm) or 195
°
C/383
°
F (5
°
C/9
°
F higher for 52 ppm).
Correction for low ambient
temperature
(Ambient temperature: 17

Correction for high ambient
temperature
(Ambient temperature: 37
