Check the fuser cooling fan.. it will still be running but the blades can break off the hub so the motor runs but the fan isn't turning. I believe we have had 2 of these do this.
IH unit bad, this is an old unsupported Ricoh unit sorry.- Carl
SOURCE: RICOH 2015 error code sc 500
Main motor/ transport motor lock/ fusting motor error.
The only thing you can do is check for any obstructions in the machine.
That needs to be looked at by a service because the problem could be a motor, a pcb, or a power supply.
It can be a lot of troubleshooting to do.

This is a fuser problem,possibly a dirty thermistor, but try resetting it first.....

then press and KEEP HELD DOWN the orange key until the screen alters into service mode. (about 5 seconds)
Then switch off the copier with the main orange on/off switch. Located just below the front cover....

yes you may it refers to a temp error int eh fuser... you may have a faulty thermistor or thermo fuse.. if you go into teh service mode by presssing teh yellow clear butto and then press 107 and then hold down the stop button the sreen will change turn the machine off and turn on again see if the errpr goes if it does it could have been just a temp error if it warms up then comes back on again you will have to look at the fuser.. you can check the fuser by touching the casing and see if it is warm after you have turned the machine back on..if it is warm the error could just be due to a build up of toner on the thermistor.. if you know about machines you can take the fuser out by opening the front of the machine up look to top right where fuser is there is a screw under the blue dial on the fuser take that out the fuser slides out put it on some paper and on the right hand side is the thermistors held inby a small screw if you take them out you may see some build up of toner on the resistor carefully clean this off.. put back together and turn on .. hopefully it will run ok.. good luck A
