I have been given a used Brother MFC-8840D. It was working fine until I had the first paper jam, the paper was jammed in the drum. Every attempt to print since then, the paper has jammed in the same place. I have turned the printer on and off to cancel the job, bought a drum replacement as it had a message to replace the drum soon. Tried printing again, same thing. Please, can someone restore my sanity and help with this problem. Thank you.
