My Ricoh MP C2050 machine is showing error SC865-01 on start up.

SOURCE: Ricoh 1515 MF shows error code sc542

Um.. I don't see an "online" or "escape" button anywhere on the printer...

It would help to know the code. Like SCxxx.

SOURCE: Ricoh Aficio MP 4000 sc 870 error after power cord

SC870 = Address Book Data Error. This is most likely a hard drive failure especially considering the power loss. This is about a $175 repair in case you want to call around locally and get estimates to replace the drive. There is an outside chance you can get someone to walk you thru the Service Mode and do the following to reload the address book:
1. Enter the SP mode
2. 5846-50 (Initialize All Address Book)
3. Turn the machine off then on again.
Good Luck
