HP Photosmart D7260 Printer, won't feed from the photo paper tray.

Question

On my parents computer they use a HP Photosmart D7260 Printer and I'm trying to print off on photo paper but for some reason it keeps on feeding from the main tray I can't for the life of me figure out how to fix this i've been though all the settings changed the paper to the right kind , in all the options, there's no reason why it should not work. Can any one give me any ideas how to fix this?
Please help
