Question about Ricoh Aficio 450 Copier
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.

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?

Tips for a great answer:

The paper transfer unit contact sensor does not detect the movement of actuator at the sensor while the polygon motor rotates.
?? Defective paper transfer unit contact sensor

1. Check or replace the harness.
2. Replace the image transfer belt unit or paper transfer unit.
3. Replace the HVPS-TTS board.
