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).

After turn the main switch off and on the error appears again????
This error means that there is a bad comunication between the controller board and the operation panel.
Did you intervew in the machine? Some tecnical intervewing?

It's not the PCU (photoCONDUCTOR unit), It's either a thermistor or blown out heater lamp in the fuser. Call a tech. The code can only be reset in service mode

670 D Engine response error After powering on the machine, a response is not received from the engine within 30 seconds. • SBCU installed incorrectly • SBCU defective • Controller board defective
You can try to reseat the connectors on those 2 boards, if that doesnt work you may need to replace those boards.

SC542 is a warm up error from the fuser.

SC 870 is an address book error.

Turn the power off on the copier. Wait 30 seconds and then turn the power back on. See if it goes away.

Let me know if it doesn't.

For the Aficio 1018. SC-320 is laser failure - the polygon mirror motor inside the laser has failed and needs replacing. You will need to contact your nearest service agent for repair.

For your RICOH Aficio 1013F - SC-551 is overheat in standby mode as far as I can tell. The circuitry that controls the fuser section ie manages the heat has problem. Unless its right near a source of heat like a heater or has no circulation around you machine you will need contact a repair agent for this machine also.
