Check you paper and be sure it is dry. Sometimes if you are in any air condition areas the paper will get damp or if you run into this when the humidity level is high. Try storing your paper in a different room that is dry. Mine did the same thing after the temp changes outside. See if you can remember when it worked fine as to what time of the year it was. Did it work fine in the Winter for example and now in the summer it does not work.
