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. |
