HP Officejet 8740 Won't Go To Sleep

[gjg3]

My printer has stopped going to sleep on its own.  I have it set to sleep after 5 minutes of no activity but it still remains on.  Since the printer is in my bedroom I have to turn it off manually because the screen is so bright.  Any suggestions as to what might be causing this?
