How to change settings/background image on HP 3310 Photosmart?

[hp3310]

Hello all! I just recently got a new HP 3310 Photosmart all-in-one. It's a great printer, but the manual doesn't tell me how to change the background image(s) on the LCD screen? There are 3 pictures on the screen, all pre-loaded by HP. One of a race car, ballons and glass bottles. It tells me the time and day and also the ink levels down at the bottem. I want to change those images to something that I pick. How can I change them?
Also, how to I program the "power save" or "sleep" setting on the LCD and printer. After 1-2 minutues the screen darkens to save power, but how do I extend that? After 1 hour the screen shuts off. How do I change that?
Thank you for your help in advance!!
