Hi it is the polygon motor failure error
2nd motor down on this link is what you need.
SOURCE: Ricoh Aficio 1018 photocopier
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.
SOURCE: Error code SC305 for Photocopier Ricoh Aficio 1224c
Its a charge corona cleaning error. Try turning the power off, wait 10 seconds and turn it back on.
If that doesn't reset it, it could be the pcu, toner collected on the mechanism.
If turning it off and back on isn't fixing it, you should get a technician to look at it to see what the trouble is.

Hi,
This SC code relates to the charge corona cleaner not working or not working properly. the charge corona is located towards the bottom left of the machine after opening the front cover. It will have a screw you can undo by hand and a cable with an end like a telephone cable plug. toner may have fallen in to the unit or the motor that drives the cleaner along the wires has decided to jam up. remove the charge corona and blow it out with compressed air. You can also remove the end of the unit and check that the motor is not gummed up. Be very careful you do not break the hair thin corona wires! Hope this helps.
