You can try shaking the toner cartridge to make the lines go away. Pull the toner cartridge out and gently rock it back and forth from side to side five or six times, then reinstall the cartridge. If the lines are still there you may have a defective toner cartridge. Are you using genuine Brother toner, or an aftermarket product?
