Try to push something thicker than a plain sheet of paper through. Cut a side of a manilla folder into a 8.5"x11" and let the printer try to grab it during a copy. After doing it's normal "grab the right side until it's skewed and stop",continue to try to push it through. Once it goes all the way through your printer check and see if it might have spit out a small piece of paper or something else. Then take your normal paper and try to feed it through your printer. Make sure you rub an alcohol swab or q tip (very little alcohol) over your ink cartridges to make sure ink is coming out of it.
Good Morning do you still need help with your printer? And did you try the above instructions?
