a: 1500 ms after the main switch (MSW) is turned on, the fixing heater (FH) turns on to heat the heat roller. At the same
time, cooling fan motors 1, 2 and 3 (CFM1, 2 and 3) rotate at half speed.
b: 1000 ms after the fixing heater (FH) turns on, the polygon motor (PM) of the laser scanner unit and developing bias
(DB REM) turn on.
c: When the fixing temperature reaches the primary stabilization temperature (135°C/275°F), the drive motor (DM) turns
on. Cooling fan motors 1, 2 and 3 (CFM1, 2 and 3) start rotating at full speed.
d: When the fixing temperature reaches the secondary stabilization temperature (160°C/320°F), the fixing heater (FH)
turns on and off to maintain the fixing control temperature at 160°C/320°F and aging starts.
e: 20 s after the copier enters secondary stabilization, the drive motor (DM) turns off and aging ends.
f: 30 s after aging ends, the developing bias (DB REM) turns off and cooling fan motors 1, 2 and 3 (CFM1, 2 and 3)
start rotating at half speed.
