Re: Ricoh AFThe control panel don't show. But appear SC672 have display.
First of all, we have to DE-CODE your letter. From what I got out of this mess - you have SC672. Read below on SC672 and answer all questions below to us being able to help you.
1. What model is your copier?
2. Have you tried to disconnect HDD and see what happens?
3. Have you ever looked at the service manual (I guess you don't have one).
SC672 Controller-to-operation panel communication error at start-up
Problem description:
After powering on the machine, the communication circuit between the controller and the operation panel is not opened, or communication with controller is interrupted after a normal startup
Possible Cause:
HDD failed (I would go this way first)
Controller stall
Controller board installed incorrectly
Controller board defective
Operation panel connector loose or defective
Resolution:
1. Replace HDD
2. Check the harness connection.
3. Replace the controller board. -
