a 2 s after the main switch (MSW) is turned on, the power relay (PRY) turns on.
b 1 s after the power relay (PRY) turns on, fixing heater M (FH-M) turns on to heat the heat roller.
c When the fixing temperature reaches the primary stabilization temperature (165°C/329°F), the paper conveying motor
(PCM) turns on. 150 ms later, the DB REM signal and the cleaning lamp (CL) turn on, and 250 ms later, the paper
conveying motor (PCM) turns on to start aging.
e When the fixing temperature reaches the secondary stabilization temperature (185°C/365°F), fixing heater M (FH-M)
turns on and off to maintain the fixing control temperature at 185°C/365°F.
d 3 s after copying is enabled, the paper conveying motor (PCM) turns off. 600 ms later, the DB REM signal and the
cleaning lamp turn off and the aging ends.
