18.1.2 Control
A. LV Cooling Fan Motor (M10) control
• For the period of time that begins when the warm-up cycle is started and ends when a
predetermined period of time elapses after the warm-up cycle has been completed.
• For the period of time that begins when the Intermediate Transport Motor (M3) is ener-
gized and ends when a predetermined period of time elapses after the motor is de-ener-
gized.
• For the period of time during which the Fusing Pressure Roller deformation prevention
control is performed
• The motor runs at a half speed during any time other than above.
• The motor runs at a half speed only when printing in monochrome mode without a
Duplex Option or optional Lower Feed Unit (magicolor 5440 DL/5450 only).
• Stopped in the Power Save mode. The motor is, however, run while the Ozone Ventilation
Fan Motor (M12) is running and stopped after the Ozone Ventilation Fan Motor (M12)
has been stopped. At this time, the motor is run at full speed for a predetermined period
of time after the Intermediate Transport Motor (M3) has been stopped and is run at half
speed thereafter.
• A door is opened or a malfunction occurs, but not when an error occurs.
B. Fusing Cooling Fan Motor (M11) control
• For the period of time that begins when the Intermediate Transport Motor (M3) is
energized and ends when a predetermined period of time elapses after the motor is
de-energized.
• The motor runs at a half speed during any time other than above.
• Stopped in the Power Save mode. The motor is not, however, stopped for a predeter-
mined period of time after the Intermediate Transport Motor (M3) is de-energized.
• A door is opened or a malfunction occurs, but not when an error occurs.
C. Ozone Ventilation Fan Motor (M12)
• At the start of a warm-up cycle
• The Intermediate Transport Motor (M3) is energized.
• A predetermined period of time elapses after a warm-up cycle is completed
• A predetermined period of time elapses after the Intermediate Transport Motor (M3) is
de-energized
• Stopped in the Power Save mode. The motor is not, however, stopped for a predeter-
mined period of time after a predrive or a print cycle is completed.
• A door is opened or a malfunction occurs, but not when an error occurs.
