Color Qube 8570 will not print black and white print out because it wants color cartridge

Dear Xerox,

We have a ColorQube 8570 and the message box on the printer says it needs a yellow cartridge but it also says I can still print out something as long as it is black and white.  The light to the left of the message box on the printer is red.

When I try to send the printer a black and white image to print, nothing happens.

I have set the image to black and white both in the software I am using and have specificed a black and white print out in the Xerox Color Qube Printer options.

Can you help me find a way to make the printer create a black and white image without needing a yellow cartridge to be installed?

Thank you.
