Sprocket printing horizontal lines on pictures

[Hille3811]

It was working great for the first 20 or so photos, then when I inserted new paper (the smart paper was on the bottom) and it started to print my photos horizontal lines started to appear on the photograph. To begin with I thought it was just bad paper however, I have inserted more paper and the problem is still there.

I've tried:

letting it cool down,

turning it on and off again,

checking the firmware (there is no update),

using Hp zink paper (I've only used this),

reloading the paper

I haven't had this for very long at all and want it to work well.

I added a photo in to show what it is doing to all photos it prints no matter what the colour is. If anyone has advice please help me!
