How do I clear a paper jam inside the Samsung Xpress SL M2020?

Close the output support first, then open the top cover — the jammed paper may be removed automatically. If the paper is not visible, open the tray and top cover, remove the toner cartridge, open the fuser unit cover, and gently pull the jammed paper straight out. Note that the fuser unit area is hot, so take care when removing paper from that area.
