a: 500 ms after the main switch (MSW) is turned on, fixing heater M (FH-M) turns on to heat the heat roller. At the same
time, cooling fan motor (CFM) turns on.
* The fan motor for second speed rotates at half speed and the motor for first speed rotates at full speed.
b: 500 ms after fixing heater M (FH-M) turns on, fixing heater S (FH-S) turns on.
c: 1 s after fixing heater M (FH-M) turns on, the polygon motor (PM) of the laser scanner unit turns on.
d: When the fixing temperature reaches 110°C/230°F, the copier enters primary stabilization, and fixing heater M (FH-
M) turns off temporarily and turns on again after 13 s.
e: 100 ms after the primary stabilization, the drive motor (DM) turns on. Also the cooling fan motor (for second speed)
switches to full speed rotation.
f: 900 ms after the drive motor (DM) turns on, the developing bias (DB REM) turns on and at the same time transfer
charging (TC REM) starts.
g: When the fixing temperature reaches 165°C/329°F, the copier enters secondary stabilization. Fixing heaters M and S
(FH-M and FH-S) are turned on and off to keep the fixing temperature at 165°C/329°F and aging starts.
h: 10 s after copying is enabled, transfer charging (TC REM) ends.
i: 30 s after the secondary stabilization, the drive motor (DM) turns off and the aging ends.
j: 15 s after the drive motor (DM) turns off, the cooling fan motor (for second speed) switches to half speed rotation.
