Is anyone aware of what this code means?

Looks like a problem with your DCPS. Is the code constant?

Thank you for your quick response on this problem. I am a Ricoh specialist but am limited with Minolta knowledge. If I can assist you in any Ricoh questions, please let me know.:o
I have reset the copier by turning the main switch on and off 6 times and unplugging the machine 6 times. So, yes the code does not reset. Is the DC power supply bad or may there be other possibilities for this code. Is this a service code that needs to be reset by a reset button or a service program mode?

By looking at this I would first check the fan...

Fan abnormality
F52-01 FM13 (power supply cooling) EM signal
was abnormal 2 seconds after
turning ON FM13. 2 seconds after
turning FM13 OFF and ON again, the
signal is still abnormal.
The machine stops
immediately. RL1
(main) is turned OFF.
FM13 (power supply cooling)
DCPS (DC power supply unit)

The power supply cooling fan will be binding. KM will tell you that you need to replace the power supply as they don't offer a fan by itself. Tech support said you may be able to find a computer fan locally but I never had any luck. I did have luck with taking the finisher off, removing the lower left cover, cutting the mylar that covers the power supply fan, cleaning and lubing the fan. Worked more often than not.

There is a fan for the 7022, 7130, 7228 series that has a compatible fan. You do have to splice the wires due to the connector being different. It works!

Hello Coptech,
Thank you for such a quick reply. Just like reading a manual. You are definitely an asset to the copier community. With 1.2mil on this bad boy, I think I will replace the assembly. Your right about taking the repair approach but the account is T&M and not willing to take the crap shoot. Once again, Thank you for leading me in the right direction.
Best Regards,
