6. Timing
T1: When the main switch is turned on, the blade solenoid turns on. The blade
releases 15 minutes after the main motor stops.
If the Start key is pressed when the blade solenoid is off, a pressure malfunction
may occur. Consequently, the copier start time is delayed by 0.2 second.
T2: The PCC starts 0.13 second after the Start key is pressed, and it turns off 0.12
second after the fusing exit sensor turns off.
T3: The pick-off pawl solenoid starts 1.49 seconds after the Start key is pressed, and
the pick-off pawls contact the drum. After 1.0 second, the pick-off pawls turn off
and separate from the drum.
