Canon prograf 4000 color calibration

[Jfrank1]

I recently had to replace the head. The printer was running fine, although I could see by comparing old and new tests that the color was a little off. I couldn't run a color calibration for a few days until I replaced a low CO cartridge. When I finally did, the color calibration ran and looked like what I could call normal, but subsequent tests from files out of photoshop all appear to have about 10 times the ink they should have. I've been through the process about a dozen times with different papers, all with the same results. Can anyone tell me what I'm doing wrong?
