C320dn error code SC534

SOURCE: Error code sc 552 on Ricoh CL7100

To clear any code on a Ricoh / Savin copier that will no reset by turning the power off / on you need to first enter the service program mode. This is a safety feature installed when repeated resets of some codes could cause damage to the machine or possible fire hazard. Most of the time these codes deal with the fusing unit. The fusing units operate at around 180 degrees celcius. Thats pretty near the point where paper catches fire so you see the need for safety there. Anyway, you can sometimes get a false fuser code if the room is cold in the morning when you first power up the copier and the machine takes longer than normal to reach operating temp. Another reason can be that maybe you didn't push the fuser back in good enough after clearing a jam and the electrical contacts did not make good contact. In these instances you can clear the code and go back to copying. Should the code come back after doing one of these resets then it means there is a bigger problem with your fuser and you need to call for a service visit to have the problem fixed.

Here is the reset for it:

1. Press the Clear Modes (yellow on most machines)
2. Press the numbers 1,0,7
3. Press and hold the Clear / Stop (red on most machines)

after a few seconds on machines with an LCD display screen you should see the screen change to display "SP mode" with a few selections. On older or smaller machines without an LDC display screen you should see a flashing "0" on the panel. This lets the machine know its ok to reset the code. Do not make any selections in this mode. SP mode if for making electrical adjustments to the copier and taking the machine out of spec can cause a lot of problems for you. Once you enter the SP mode you just need to turn the machine off / on. (make sure you do so with the main switch that you have to rock back and forth and not the button that just gets pressed to shut down the machine, the main rocker switch is often located on the front door or on the left side of the machine, sometimes covered by a swinging cover you have to lift first)

If you do not hit the keys in the right order, the machine will not go into SP mode. You can just start over with step one untill you get into SP mode.

After doing this and the code resets but then comes back again or gives you another code, you'll have to place that service call. If not then happy copying to you.

"clear modes", 1, 0 , 7, then (hold) "clear/stop" for a few seconds until "sp mode" comes up. turn main power off/on (red switch).
If code comes back there is trouble with the fuser that needs to be repaired to clear code permanently.
