SC 320 - Polygon motor error.
The polygon motor does not reach its operating speed within 10 sec. after the polygon motor on signal,or the lock signal is not detected for more than 40 ms continuosly during operation.
Possible causes polygon motor defective,poor conection of the interface harness which connects the polygon motor driver and the IOCSS board, IOCSS bboard defective.
The SC can be reset by turning the main switch OFF and ON if the SC was caused by a sensor error.
To reset SC press yellow key 1 - 0 - 7 and STOP ( red ) key for 3 seconds,enter in the SP mode, enter SP 5-810 ( SC code reset) and select "1".Then hold down the Photo mode key and the # key at the same time for at least 3 seconds(this does not require the main switch to be turned off and on).

Enter SP mode - Clear button (yellow key), 1 0 7 and hold and press stop button (orange key).
Enter SP5-810 (SC code reset) and select “1”.
Then hold down the “Photo mode” key and the enter key(hash) at the same time for at least 3 seconds (it is not necessary to turn the main switch off andon). If the machine beeps 5 times, the reset was successful. If it only beeps twice, the reset failed, and you need to repair the machine.
Possible causes are the fusing thermistor in the fuser unit, or the power supply unit defective.
Good luck and please rate me, thanks.
