Hello aguider0213,
Welcome to the forums:)
I saw your post about your printer no longer printing after a paper jam. I would like to help you, however I would need to know which model of 3520 you are working with. Please respond and I will look into this for you.
HP Deskjet 3520 Inkjet Printer
HP Deskjet 3520 e-All-in-One Printer
Thank you,
