Digital BW, The Print

Remember the Epson X800 printer series will give you a similar message if the "black ink mode" does not match the cartridge. By mode I mean:
The printer is in MATTE mode and you load a PHOTO BLACK cartridge or
The printer is in PHOTO mode and you load a MATTE BLACK cartridge.

If that's the case, just remove the cartridge and follow the procedure to change inks mode described in the manual.

Good luck!
