Why did you replace them? Have you tried to fit a 25cpm iCTL to it? If so, you've probably blown the fuse on the board. The Diana's boards cannot be chopped and changed, they have to have the correct board in.
I Replace it because machine cant print from network card, and my custumer only can print with usb cable, so when i try replace both of them with others nvram/eeprom machine, machine running well print via network.
And then i order new nvram and eeprom but when i replace it SC 995-04 appers
The MPC2030 (D037) Controller NVRAM part # is D0409590, EPROM is 14077036. Are these the parts you put in? Don't forget that the D037 is just basic printing (RPCS only) and twain scanning (totally different from the MPC2050/2550). You might have hosed the controller somewhere along the line when you started swapping things around. If you have to replace the controller, the part # is D0405740.
I order this code D0409590 for NV-RAM on CTL Board and this Code 14077036 for EEPROM:AT24C128B-PU on BICU Board, as I know MPC2030 only used RPCS Driver Printer on standar one and PCL Driver Printer for Options.
The SP Mode SP5985-001 for device setting was enable, because when i enter sp mode its appear 3 options sp mode, copier, printer and scanner.
