HP Laserjet 1020 printer prints vertical smudge on paper. The text at the right end of the paper is also fading. How do I fix this? (Attached picture)

Most likely this is a cartridge error. Have you tried a different cartridge yet or inspected the drum on your current cartridge to see if there is a corresponding defect on the blue/green drum of the cartridge?  That issue can also be caused by a failed fuser unit or something like a label wrapped around the fuser, which is the component that bonds toner to the paper.

Thank you. I inspected drum of the catridge and I see a ring formed on it at the exact position where the smudge appears on the paper. I wiped the ring formed by toner powder off, but the ring and smudge reappears while printing. Is this issue with the toner catridge or the fuser unit?
