Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
I am posting a link below, where you will find all the ways to remove a jammed paper, please follow the steps to remove the paper, let me know, if you need any further help otherwise, please remember to give a positive rating, as that is the only way I am compensated for my time and effort.
OK, please wait.
As you cannot see the complete paper, it means it is inside the printer, do you have checked from the right side, removing the drum, transfer guide etc. ?
