To clear an <a href="https://www.hpprintersupportpro.com/blog/hp-printer-paper-jam/">hp printer paper jam</a>, switch off your printing device. Now, open the cartridge access door and take out the jammed paper inside. After that, close the access door. Turn on the printer and try to print. Note that sometimes the printer may tell you that there is a paper jam even if there isn't. This can happen if your pickup roller is dirty. So, take a clean piece
of paper and clear it of dust and debris.
