How can I print to a hp officejet j5780 printer without the color cartridge?

My color cartridge is out and I want to print a gray scale picture. However, the printer flashes replace cartridge (when the cartridge is in), and insert cartridge when I take it out. I don't have a spare color cartridge and the black and white is fine. I'm printing in gray scale but can't get the printer to get past the error message? Any ideas?


Solution 1:

This question was answered by pointing out that a color cartridge is sometimes necessary for greyscale printing.

A different printer was discussed, but the reasoning may be the same.
