Rollers not picking up paper and reporting a jam

My Canon pixma MG6660 has been working for years, after one paperjam the rollers are noisy and it doesn't pick up the paper from the feeder, if I do try to push the paper up, it either reports a jam or jams the printer. It won't let me into settings as it has an error message saying to take it to the nearest maintenance shop. Many thanks for reading.
