How do I get my brother 1840C fax machine to work?

It says my color cartridges are empty but I just would like to print in black. The black ink cartridge is new but since the color ones are out it wont let me do anything. At one point there was an error code 29. do you know what that is? How do I override color and just print in black and white? It was given to us so we dont have a manual but i down loaded one from the brother website no help there!

done
error 29 is cannot detect ink cartridge.
you cannot use it without color ink even if you dont use them they must be in.
