[D4Stone]

Just started recently having this problem. Left side of page has solid black line about 1/4" wide top to bottom. I checked register of paper and it is perfect. Using windows XP Pro on a Dell computer. I checked the green roller and it is clean. Using genuine HP cartridge. Don't know what else I can tell you about this problem
