turn the cartridge over , open the flap that covers the drum, you should also be able to see the mag roller with the toner on it . Is there a corresponding line on the toner roller with your print ? also if you look at the top of cartridge were the scanner(hp likes to be different) writes to the drum there is a black charge roller on top of the drum, is there contamination or build up on the charge roller. if yes, it could be paper dust or if remanufactured faulty(inexpensive) parts. or the mag roller(toner roller) and charge roller aren't being replaced when remanufactured.
