There may still be small fragments of the paper jammed in the machines roller system that you might be able to get to.
At worsethe roller has teeth busted on the gears and pulleys.

replace the thermistor and thermostatic some time maye be power supply

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).

SC543 is caused by a defective Fusing thermistor. check or replace both center and end thermistor this will solve your problem

i don't think there is an sp for that
there is an sp only to temporary reset the add toner

That code indicates a fuser overheat error or hot roller fusing lamp overheat. Refer to your manual if you have it. Good luck.

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.
