Both of these lights usually come on at the same time. Remove the misfed paper according to the instructions for your specific Sharp copier model and you should be back in business. The majority of jams in copiers is caused by paper. If your machine begins to jam frequently on any given day, try replacing the paper in the trays with a brand new unopened pack of paper and see how that works. If this does not remedy the situation, call for service.
Machines still do infrequently jam for other reasons.
