...contact Epson Tech Support. Trust me, the problem you're having with the rollers is NOT because the printer is a 2200. You may either have a defective machine or perhaps it was not properly set up. Different papers also use different roller spacing, so if that doesn't jive, it might cause the problems you describe.
As for color, I'd say that at least 80% determined by user configurations. IOW, YOU are in control of the color through your camera, photoshop, image file, monitor, and printer color space settings. You need take responsibility for learning how to control these things. There are several good threads in the DIGITAL IMAGING forum (which is actually where this thread should go) dealing with proper color settings with the 2200.
These sound like minor technical issues which need to be straightened out before you truely judge the 2200. This is the printer that most pros use now, and all things considered, it delivers an absolute amazing bang for the buck.
I've had and used one for a while now, and other than a few glitches installing it, have had nothing but fantastic results with dead on color...
