Malfunction problem I got a Ricoh 1022/1027 at the garbage....the unit powers on but it gives an error code....up at the left corner it says "SC 792" and in the middle it says "SC 998"... Can you help me???

some potentially useful information can be found here: what the error codes mean, and the services manual; (I have pointed to error code 792 but the others are different pages), there is a copy of the service manual too. This is only a starting point !

finisher cable not plug into copier. I f you don't have a finisher don't worry about it or you need to remove bridge unit to get rid of code.

Hi

Error code sc 547 means "Zero cross signal malfunction". This error appears due to a faulty power supply. This error code may also appear if the input board is defective or the BIC Unit is defective. Turn off the printer and unplug the printer for 30-40 minutes and check if the error still appears. If you see he error still appearing then try and rest it using the following reset method--
To reset the SC code by entering SP5810 and select 1.
Now hold down the photo mode key and the # key at the same time for at least 3 second.
Then turn the machine off and on again.
If the same issue still appears, you'll need to check and replace the Power supply or the Input (IOCC) boardt.

Hope it helps...

that appears to be a finisher communication problem. Check the connectors..
