SD card wont read in Epson R320

[sweatyk]

When I try to put my SD card into my printer it will not read it. The message I get is "disc in drive F is not formatted". This is the second SD card that I have tried with the same results. I have reinstalled the printer software and still does not work. Can anyone explain what I might be doing wrong?:mad2:

Does it work in a normal card reader? Or more than one camera for that matter?
