If a paper jam resulted in a torn sheet, or you tore a jammed sheet getting it out then there could be a scrap of paper in there somewhere, or even some other foreign object. You may have to look very hard to ensure the paper path really is clear. Use a torch and maybe a dentst’s mirror to see right inside.
In so far as you can, clean all paper guides and rollers with isopropyl alcohol. Inspect everything very carefully - it could be that some small plastic part has got broken. Look for anything that looks different of the right and left hand sides.
Paper quality is important in avoiding jams. Make sure you’re using good quality paper, and that it’s bone dry. Any moisture it might have picked up will make it prone to jamming.
