Ricoh Aficio 1232c

All,

I am getting "Toner cartridge setting error." Toner cartridges are not set properly: Black, yellow, magenta, cyan.

I have replaced all 4 development unit and cartridges and I get the same error message as above..

Any ideas what else I can check?

I think there was a bulletin relating to the detection board, it's the one the dev unit leads go to.
