Hi. Couldn't understand why I can print A4 but A3 kept jamming up.   Eventually saw with a torch there was a small piece of metal hanging down on the far right near the printer cartridges that was preventing the A3 feeding through.  I ended up getting it out and its a spring abut 2cm long with a could of small serrated disks on it.  I assume this is some kind of guide wheel that has come loose so isn't critical as seems to print ok now.  Just wanted to check this isnt going to cause issues going forward?

Those are star wheels and guide the paper without leaving ink marks. The printer should continue to work ok, although there might be a small increase in jamming.
