Hello, I'll be assisting you today.
To fix the problem, unplug the printer power cable. Open the covers and remove any cartridges and look for loose paper. Use tweezers to pull the paper out or the eraser end of a pencil to move the rollers and get to the paper. Use your fingers to move the rollers as much as you can to get the paper.
Let me know if you need additional help so I can assist further.Also, please rate my answer below so based on your satisfaction.Thank you.
Sorry. I had some internet issues myself.
Most likely, you will need to remove all the outer screws to open the covers of the main printer area to remove the paper.
This is usually how it is cleaned from debris and paper inside the paper. You will need to find all the screws that hold the main printer chassis and remove the screws.
