Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Open the paper trays, all of them. Remove the paper from them all. Turn Off the printer (And remove any paper stuck in it after that.)
Do you have a Windows PC or an Apple computer? the print queue needs to have the job stopped in it, or Cancelled. The way to do this varies between Windows and Apple computers.
