I usually buy the copy paper in the red wrapper but when I was in the store they were having a special on the copy paper in the blue wrapper. I figured I would give it a try. When I finished the paper I already had open I started using this paper. This paper seems to be thinner. Once it was in the paper feed for a little while I noticed all the paper starting to curl toward the back of the printer. The paper also developed a pattern that almost looked like it had been wet in areas. Now when I send something to be printed the feeder can't pick up the paper and I have to keep trying to feed it manually. I am going to try to bring it back and trade it for the red wrapper paper.
