Hi,
I have had the same issue as on this post: Ever seen this error message? - MK not working on 4880 - #21 by pandabob
The windows driver pops up this window:
“The selected media type/print quality setting may not be compatible with the installed ink cartridge
Photo black/cyan/vivid magenta/yellow/ light black/ light cyan/vivid light magenta/light light black
Please check your new media type and print quality settings in the printer software.”
I just wanted to propose a solution to this problem: use another driver for the printer.
You can buy Turboprint (Linux) or Printfab (Windows) for 50 bucks online, it works very well and it allows easy ICC profiles creation. Personally I never use Epson drivers anymore, Printfab is way better and it bypasses this bug in the Windows driver.
