problem in the copier sc543

SC 670 - Engine response error.
After powerig on the copier machine,a respons is not received from the engine .possible defect controller board or SBCU installed incorrectly.Try reset the code to turn ON/OFF the main power switch.

Hi, it looks like a bad controller board. Try resetting it from in service mode with 7807. Also if you can view or printout the error history with 5990-004 for further trouble shooting. Hope this helps

sc670 is an engine startup error. A lot of times if you reset the copier (turn it off with the orange switch on the left side of the front cover, then turn it back on) the error will go away. If it doesn't the BCU board may need to be replaced.

dear sir; the error code 320 on ricoh af 2027 it's means laser polygon motor problem, the laser unit right under the toner unit, litlle bit left. some error code can be reset why don't give them a try
1, power on the machine

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.

This seems to be a finisher communication error. If you unit has a finisher on it check the connector.
