Ricoh Afficio 250 SC900 Code Reply

I replaced the top original paper feed that goes over the glass...I plugged it into the machine inadvertantly while it was on...then the code SC900 popped up. I checked fuses and fuse #5 was blown, I replaced it and the new one immediately blew. I am not sure if it is the nvram, or the entire OICSS Board. If I change the board would it come with a new nvram? or could there be another problem that triggers the code and blows this fuse.
Thank You,
REv. Scott Gallagher
PS Our church really does not have the funds to buy a new copier so any help is greatly appreciated.

If he does not have another power supply, I would suggest I begin to disconnect boards and parts one by one until the fuse stop jump. The problem can be anywhere.
Fuse 5 makes work the peripheral.
Disconnect to finisher ADF if it has them.

The problem is getting parts for 220s and 250s is tough. I'm running out of sources myself. Do you have any way of checking the power supply?

Afficio 250 SC900...copier will not operate

Is the SC just 900 or is it SC900-01? If it is 900 then it is a total counter error stating that the machine exceeded 9,999,999 copies. If the machine does not have this many copies then the NVRAM is defective. If the SC is 900-01 then the total counter is not working properly. Causes could be .... the mechanical total counter defective, mechanical total counter disconnected, or a poor connection at the total counter. Hope that it is the latter of the 2 codes.

When developer goes bad you use more toner for one thing, but the main sign is a gray background in your copy. The print should be black but appears to be gray. The ricoh 350/450 was always noted to leak toner and developer as it runs. Check your machine and see if you see any small piles of toner, which also has developer in it, in the machine. Ther are small seals made of felt that need to be replaced if you have this problem. These seals rub against the drum sides....Good luck.
