recently got a second hand Ricoh CP 308B+, which is a retagged Rex-Rotary 1225B+. Probably the motor board doesn't do it anymore.
In order to verify the testing: does anyone know where to get a circuit sheet for this machine?
Unfortunately in the Service Manual doesn't provide this information: https://stuff2233.club/~dick/manual.pdf

For troubleshooting: the “close the covers” indicator is lit. On p. 386 it says, it could be the case that the 10A Fuse is blown, but that Fuse is doing well. So I suspect there might be somewhere a capacitor broken. A circuit sheet would do a good job for some systematic testing.

Many thanks in advance, all ideas are welcome!
