* The operation start temperature can be modified by SP.
*1 If the imaging temperature reaches 39°C (MP C4504/C5504/C6004), 41°C (MP C3004/C3504)
each fan will continue operating until it falls by 2°C.
*2 Operating condition:
• When the time interval from the previous job is less than 10 minutes. Or, when the time
interval from the previous job is more than 10 minutes, and 5 minutes have elapsed from start
of machine.
*3 Operating condition:
• For 36°C or above, full speed rotation at 24V
• For less than 36°C, rotated at low speed with voltage reduced to 13V (rotating speed
approximately 50%)
• Changes from low speed rotation to full speed rotation when printing continues for more than
5 minutes while the temperature inside the machine is 36°C or lower

Cooling operation after output

Usually, after output, fan operation is suspended.
If the temperature in the machine after output is high, fan rotation is continued after output to cool
