I have taken all paper out of the back of the drawer and used a flashlight to look in and see and there is NOTHING blocking the drawer. I have rebooted, unplugged, restarted...you name it. I have opened the back, no paper jam and no paper jam noted on the screen. When I try to print letter size (drawer 2 paper) it asks if I wish to print on legal (Drawer 3 paper). I have even removed the Drawer 3 additional paper tray accessory and drawer 2 still wont open. Please help.
