Why do my pictures have lines on it?

I just got my Polaroid snap and it works great! Though, I guess I should have been more careful with it when I let a friend use it and he dropped in on my carpet floor. I'm not sure if this caused the problem but now, whenever I take a picture, when it prints out it has this pattern of lines on it. I tried charging the camera, cleaning the lens, or even adjusting the lighting of the room but the lines are still present. I just got this camera so I am not sure on how to fix this issue!
