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.

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.

SOURCE: error codes SC545 for Ricoh Aficio 1045

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

Ricoh Aficio error code sc 320 what is this and how can I fix it.

Polygon mirror motor error/lock. Unplug the copier. Wait 20 seconds. Plug it back in. See if that makes it go away.

Otherwise you should get a hold of a service technician but getting parts for a 250 is very tough. It could be the polygon motor, the power supply, a cable, or a board. It will take some time to troubleshoot.
