Make sure the fan cable plug is properly seated at J19 (controller
card).
Turn the MFP off, and disconnect the cooling fan cable from
connector J9 on the controller card.
Turn the MFP on. Within a few seconds, the controller card assembly
should apply between +24 V dc to pin 2. See “Controller card” on
page 5-4 for more information.
If voltage is present and the fan is not turning, replace the cooling fan.
If the fan still doesn’t function, replace the controller card.
Note: The fan speed is controlled by a module on the controller card.
Between +8 V and +24 V dc are constantly supplied at pin 2 (J19).
Pin 1 is ground while pin 3 receives feedback from the fan motor.
If voltage is not present, see “Controller card” on page 5-4 for more
information.
