We have a FS-8000C Installed about two years ago. The customer upgraded to Adobe Photoshop CS which now produces a color shift when printing to the FS-8000. The shift occurs when printing archived or new files through the "CS" Version. The shift occurs in both CMYK and RGB. When the archived files are printed using an earlier version no color shifting occurs.

The only time I have had trouble with color shift, I upgraded the printer firmware and driver and that fixed it.
