I've never needed these 2 colours before so rather than buy litres of LC & LM I figured I could fill them up with C & M.
I have set the configuation as a second C & M but when I do a Test Nozzle Print it shows the second Cyan & Magenta missing in the nozzle test. When I print an Image the Colours are all wrong.

If I configure the 2nd C & M back to LC and LM and do a nozzle print test it does Print the 2nd C & M test strips. But if I try and Print the Colours again are different and wrong.

Any Help for a solution other than buying 2 extra colours that I've never needed before?

Thanks
