R2880 problem

GF-PARIS-ROMA PRO 8:22am, 2 February 2009
I have a new Epson R2880(2 days old). Last evening, for the first time, I tried to use the Advanced B&W Photo setting in order to print my 5x7 BW picture.
My printer went crazy, the Power Light started blinking, the paper has not been loaded, and the printer did not stop running as if it was printing without paper. I had to unplugged the power to stop it. Actually, I dont know if the problem was the "advanced B&W Photo" setting or something else. (BTW, I have kept "photoshop manages colors" setting when I tried to print).
