Why is my HP Laserjet 1012 printing smears down the center of the page?

These smears are small and run vertically down the center of the page. They are about 2'; apart. I changed the toner and the smears still appear with the new cartridge.Why is my HP Laserjet 1012 printing smears down the center of the page?
Your printer rubber ';drum'; is damaged. It leaves a gap when printing. Replace!

in 20+ years of printer reapir i have never heard of a '; rubber drum'; lol....... if you have tried a new toner and still have problems chances are you have a torn fixing film ***'y.... call the local hp repair shop and ask for the reapir cost to replace a fixing film and they will let you know. if you live close to me in indiana i can fix it for you cheaper than most places ......................
That means fuser unit is bad (film broken) replace that fuser unit.
