HP 895Cxi printer Auto/Off feature?

Hi all,
I have a HP 895Cxi printer that I absolutely love, but one feature that I can not figure out (maybe it’s just not an option? ) is the ability to have the printer power itself off after a certain time period. I’m not sure if it will burn itself out when it is idle, but since it’s on a bottom shelf that my wife refuses to check after printing something, the printer stays on for hours…….
thanks for any suggestions other than getting rid of the wife, replacing the printer would be less expensive 😉
