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 2quot; apart. I changed the toner and the smears still appear with the new cartridge.

Your printer rubber quot;drumquot; is damaged. It leaves a gap when printing. Replace! t4ke c4re

in 20+ years of printer reapir i have never heard of a quot; rubber drumquot; 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.
