I have an Officejet 6000 E609a that is used EXLUSIVELY for printing black and white text documents. However, I discover that when I check the ink levels, cyan is also being used up. Can I set up my computer to use JUST BLACK for printing black text? Doesn't make sense to me. This printer is used in our church office and I am tryiing to save the congregation money. I already print many things on draft. But there's a lot printed at normal quality.

This is not the right printer for B&W only usage. To keep the semi-permanent printheads healthy there is some amount of color ink used in each print job, after the printheads are waved back and forth in printing some ink is used to keep the printheads from clogging. See here for a discussion of how ink is used, you have a printer know in that page as IIC which has ink tanks for each color and semi-permanent printheads. Most recent IPH printers would allow printing in black only, or even printing with only a black cartridge installed. An inexpensive B&W laser printer may also be a good choice.
Additionally, if you are printing in automatic duplex mode the front page will underprint with cyan to make the ink dry faster (not intuitive, but it works).
Printing in draft mode uses about half the ink. For IIC printers like this one there is also some overhead with each print job. It is more economical to print a batch of 100 pages at once rather than 50 jobs of 2 pages.
