Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That sounds like a very tough problem to solve - if the paper stack or a great deal of it, has fed into the printer and jammed there. Such jams can be severe, so proceed with patience and caution.
Try turning the printer back On again - after removing all paper that is easy to remove, from the printer. The rest might, hopefully, be expelled by the printer.
But note: if over 4 or 5 pages have fed in at once, all at the same time, then this is a bad problem and a grave and unusual issue. Do not turn the printer On again - take the printer to a shop. A skilled repair tech will be the only person likely to fix up the situation without damaging the printer... and also be able to prevent it happening again, hopefully.
(If I have not understood what you are asking about, please reply letting me know more about the problem, and I will advise you further.)
