After looking at A3 Printers I purchased an Epson R1800 off ebay. Test printed it at the sellers house and the quality is good and all that, took it home, tried to print some stuff grayscale the print has a green tint to it but after changing photo black, matte black cartridges it has a blue tint. I have tried using different colour profiles (RGB, CMYK) but it doesn't seem to print grayscale properly. I am thinking it's maybe the cartridges problem (not official and it uses a mixture of brand)?
Thanks
