HP OfficeJet Pro 8720 is stuck in a "demo mode"

[CharlesWorlton]

I have an HP OfficeJet Pro 8720 that appears to be stuck in some sort of product demonstration mode.  The display never shuts off and it keeps moving from screen to sceen showing me about the features of the printer.  I want my display to go to sleep.  It is ignoring the setting in "Power Management --> Sleep Mode" where I have set it to sleep after 5 minutes.

I am not sure if this is related to the problem.  I checked the manual and found no mention of a question mark icon in the manual:

There is a question mark icon "?" displayed on the left of the display inbetween where the "home" and "back" icons would normally be displayed.  When I touch the home icon, the question mark icon is displayed and the "home" and "back" icons are hidden.  When i touch the question mark icon, the "home" and "back" buttons are displayed and the question mark icon is hidden.

Hi @CharlesWorlton

Welcome to HP Forums. This is a great place to get support, find answers and tips.

I understand that the Printer seems to be stuck in the " Demo Mode ".

I'd like to help.

I suggest you perform a Printer Reset.

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

If the issue persists, We can perform a Semi-Full Reset to Factory Settings.

Since these are critical steps, I will send you a Private Message with the instructions.

Could you please check your inbox on the Forums page for the Private Message.
 

Thank you. 🙂
