The best way I have found to control this with my Epson 1200 (admittedly a different animal but I think the essence should hold) is to convert the file to RGB before printing and to use a curves adjustment to bring it to a truly neutral gray color. The best way to choose the right curve is to make a posterized 20 step gradient to act as your standard. Print this out and then analyze where the color shifts are. Use the info pallet to identify what rgb values need adjustment and then make that change in the correct color channel. Save the adjustment, apply it and print again (you must print on the actual paper you will use for your final prints but it is a good idea to cut the page into halves or quarters to get several tests per page). Continue to iterate until you have a curve which brings the grayscale to neutral. You can then use this on your actual images to make then neutral too. Hope this is clear. Contact me off list for any further details.
