Tray 1 jams at registration actuator with front edge just below metal IPR guide. Tray 2 works fine. Mylar okay. Cleaned pickup tire with rubber rejuvenator. Still jammed same place though first sheet went higher just at entrance to fuser. Is this case of pickup tires need to be changed because paper not reaching registration sensor in time? Or could it be something to do with MEA assm. feed roller though the paper from tray 2 goes thru fine? Any help is appreciated as not much experience on this problem on this machine.
