Paper jammed (Dell lase Printer 1720dn

Open the back cover and look for paper wrapped around a roller back there. That is the most common cause of the issues with this machine. The other thing you can try is to push down on the little flaps where the paper comes out of the printer. These get stuck and need cleaning/replacement all the time in the later life of these models (1720's).
