I load a piece of sheet paper using the printer controls naming the paper and as sheet, then with a Mac, I enter print and with the print menu of the Mac I set in the layout the paper is sheet, and when I check the printer monitor on the printer paper type it confirms I loaded sheet paper, and yet when I attempt to print, the print monitor now says "Load roll for next job" and will not print on the sheet loaded. What do I do to get this corrected? I have disconnected the printer, left it off overnight, rebooted the computer and printer, and it keeps coming up the same. BTW, the previous paper used was roll and with that the printer worked properly. Has anyone else had this problem and what do I do to correct it.
