How do I clear a paper jam on the HP DeskJet GT 5820?

Press the Resume button to clear the paper jam. If this does not resolve the issue, refer to the full User Guide at www.hp.com/go/support or the electronic help installed on your computer. Important: before tilting or moving the printer to clear a jam, ensure the ink valve is turned to the locked (right/horizontal) position, and return it to the unlocked position before resuming printing.
