I followed all of the directions for testing the cartridges. Each cartridge independently had a solid light. I put both cartridges back in and powered off and on and got a solid light. WHen I try to print on a cookie with the solid light, the cartridges will move to the front, beep a couple of times, and then it moves to the back, lowers the tray, the light blinks, and the error out of paper is displayed. Please help.
