c8000+EF-101+RU-508+FD-503+SD-506+FS-521
all options after the RU are not displayed on the panel
the problem began when one of the connectors between the RU and the FD has been put in a wrong place
the machine is working very well if we don't attach any of the finishers(FD,SD,FS)
we have tried to connect only the FS to the RU but still the same problem
