7. Detailed Descriptions

Cooling of actuator

Air taken in from the drive cooling fan
machine.
* MP C4504/C5504/C6004 only.

Cooling in controller box

Air is circulated by the controller box cooling fan installed in the controller box, preventing temperature
rise in the controller box.

Crisis management when temperature rises in the machine

In order to suppress excessive temperature rise in the machine and maintain equipment quality, a
temperature sensor (imaging temperature sensor (thermistor)) [A] is installed in the machine. The imaging
temperature sensor (thermistor) detects the temperature environment in the machine, and controls
cooling operation.
Overview of cooling operation in the machine
The temperature in the machine is detected during output and after output, and the interior of the
machine is cooled by fan operation (stepwise operation of fan, prolonged fan rotation after paper
has passed through) according to the temperature inside the machine.
However, if the temperature inside the machine rises significantly due to passing a large volume of
paper, in addition to fan operation, the CPM is specified to control the temperature in the machine.
Cooling operation during output
Perform cooling operation under the following conditions.
