Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
It is only fair and honest to say, first, that this sort of problem usually results in a printer either going to the repair shop (albeit not expensively in all cases), or else being wrecked in the effort to extract the paper... or else, being replaced as a whole. It's no a minor error in most cases.
On the other hand: Where exactly in the printer is the paper?
And, what maker and model # ***** printer is it?
With that information, I will be able to tell you whether the releasing of the paper will be simple (as opposed to, the correcting of the problem so it doesn't happen again, which is seldom very easy.)
I think we first need to determine what actual model of printer you have, so as to access and give out advice that actually applies to your model of printer.
Look on the manufacturer's label on the back side or the under side of the printer, please What model # ***** ***** there?
And, does this resemble your model (aside, perhaps, from the color of the case) ?:
That information, unfortunately, is not indicative of the true model #.
Can you look on the underside of the printer, please? that must be where the true manufacturer's label is.
If turning the printer onto its side, turn it onto the side that is on the right as you face the front of the printer. And be careful not to let the top part flap loose, swing loose, and break, or break something.
