Yea, had quite a few doing this, not always for the same reason though. Do the basics first and that includes changing the pick up spring and changing the clutches. From memory there is a bulletin about jamming from tray 3, it's a one way bearing in a gear I think, I will hunt around and see if I can find it. I normally keep them on my lapie as trying to find anything now on Konica Minolta's wonderful tech site makes me want to kill someone after 10min.

I have been getting the same jams on C454s (same feed systems as 284). The cause seems to be the little torque limiters on the sep roller shaft...they are filled with chinese black grease that goes hard causing the feed to stall, so gives J20 jam codes. Wash out the grease with IPA and relub with a little silicon oil...machine happy again. Or just get new parts..and hope not pre greased!

You can change the spring (interne notification KM) but you can look also the hook in the middle of the right door, déformation ?
