iX6820 - Is it possible to print BLACK when the color ink is empty?

[diasmade]

My color cartridges are out but my black pigment is totally full and I can't get it to print in black only. 

I tried selecting "print in greyscale" but nothing happens. There's a flashing yellow button on the printer that doesn't allow me to proceed.

Is this possible at all?

TIA

Hold down the STOP button with the red upside down triangle for 5 seconds. You're welcome!
