Thanks for the response I am doing this, but I still have a full ink PGBK and only half of BK. I have just replaced all 3 colour inks ( which isn't cheap ) as I rarely print in colour, only black and white spreadsheet files, I would have thought my colour inks would remain near full and it would use the black ink. Maybe the printer itself could be faulty?
is a rare thing. The black as in commercial 4 colour printing is intended as a shadow enhancer- hence it is known a K as in RGBK-[meaning Key] to get a true black all colours print with black overlaying. Some printers do have a text only option, but whether it applies to your particular printer i would not know, as some other high end models have a 'Photo black' with an additional cartridge to do it with. Some older Lexmarks had black cartridge interchangeable with a colour cartridge- If you wanted black only black Cart in if you wanted colour colour cart in and all three colours overprint to give a sort of black- but these I think have long gone the way of all things.
