Targets mcode mixed! - Error is displayed on the LCD screen.
This means that you have inserted mixed media brands into one or more recorders. All seven recorders must contain the same exact discs.
Press the exit button <-- to clear the error. All recorder drive doors will open. Remove the mixed media. Insert the correct media.
Note: You may still burn to this media. Just wait for the next round and insert only that brand into the recorders.
