Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Are you saying that you are trying to print, and it outputs a blank page (no ink where black should be), or it won't even allow you to print because of the color ink messages?
Thank you for confirming, and my apologies for missing you earlier, the system showed you had gone offline and I did not receive a response to my initial questions so I had stepped away for a bit.
Unfortunately what you are wanting to do is not possible.This is a color printer, and as with all modern inkjet printers, ALL inks must be present and accounted for. Even if you don't intend to actually ever print in color, the color inks are still necessary for normal maintenance and cleaning processes which are automated. If even a single cartridge is low or empty the printer will refuse to print, as doing so would cause permanent damage to the printhead nozzles.
To proceed you must replace the empty color cartridges.
If you only ever want to print black, you'd be better off buying a new printer that is suited to this task. A black only all in one laser is around $125: http://amzn.to/1JSHOlQ
My apologies for the news.
