Epson wf 7110 not printing colour

Hi,

I have a epson wf7110 using dye sub inks.

The colours was becoming slightly green on prints and because the printer was left for a few weeks I thought it may be a clogged printhead.

I done a few system cleans and test prints and it was still the same. So I bought and put on some printer genuie power flush to the printhead , applied it to colours and done a system clean. Now the printer will no longer print any colour at all! Just black, on a nozzle test there is no colours coming out.

Done hours of test prints to see if it will just work itself out and still nothing.

Any ideas?
