    [Electrical] Sharp MX 7040 MXFN22 close finisher front door.

    We have replaced the finisher main board. We do not get 24v at the switches. Any ideas?

              I got out to this account with the tech. After trouble shooting, the finisher power supply 24v supply was only 5v. We swapped out the power supply and the problem was resolved.
