Te copio lo que he encontrado en Epson por si puedes solucionarlo:

2. Question:
I have already installed the Matte Black inks into my Stylus Pro 7600/9600 printer as part of the initial charge cycle
and now I am getting "Wrong Cartridge” error and the printer will not initialize even after placing the UltraChrom
Black/LBlack inks into the printer. What is wrong and how should I recover from this?
2. Answer:
You must remove the Matte Black ink and initialize the printer using the UltraChrome Black/LBlack ink that shipped
with the printer. If this does not work contact technical support for assistance. If the ink initialization flag data is corrupted
the printer may not be able to recognize the UltraChrom Black/LBlack ink cartridges and it may be required to
change the NPD value under Maintenance Mode 2* to “0” to get the printer to initialize. Make sure the customer has
the UltraChrom inks installed then switch the NPD value to “0”.
1. Power Off the printer. Press Paper Source + Paper Feed - (down) + Cut/Eject buttons then power On the printer.
2. Navigate to Service Config mode then change the NPD value to “0”.
