Epson R200 printing wrong colors since replacing ink with Supermediastore's compatible ink

[BLeonard]

I bought compatible ink jet cartridges for the first time from Supermedia Store rather than Epson cartridges. I originally just replaced the black which was out and had no problems. Later when it stopped printing altogether I went ahead and replaced the others. Now I'm getting wierd pictures where the asphalt drive way is pink and white buildings are pink.

The Epson Utility shows the colors in the right places but it hangs when I try to do any diagnositc tests.

Any ideas? I bought two sets of these ink cartridges.
