If you have the capability to update the firmware (it uses an IC card) I would do that first. Unfortunately on this model there is software that is stored on the controller that can become corrupt. If that happens you have to replace the controller.[QUOTE=Muhammad Ali;209911]I have a ricoh 1075 copier ...

E31 is a firmware update failure. SC 820 is related probably to the E31. You need a service technician that can try to recover from the E31, before you take more drastic measures.
