HP ENVY Photo 7855 frozen on the loading screen

[stephanieinok]

My HP Envy Photo 7855 printer touchscreen has frozen and will not respond to any of the numerous troubleshooting recommendations I found online.  I have already attempted the following suggestions:

1. Restarted printer several different ways
2. Verified no paper jams
3. No errors are showing on the display because it is frozen
4. Reset printer
5. Tried several different power outlets (including directly from printer to wall outlet)
6. Unresponsive when connected to a computer directly with a network cord

The only method I haven’t attempted is a full factory reset.  I cannot find anything online publicly that explains exactly where the reset buttons are. 

Please provide some more guidance on location of reset button(s) and/or if there might be something else to try before giving up.  Thank you.

If the above does not work there is a another reset but it will ask you to insert the original setup cartridges. Possibly there is a way to bypass that setup

Here is the secret reset menu,watch at the 1 minute mark.

let me know if this helps.

I'm afraid my touch screen is completely unresponsive, so I would need to reset it another way, if possible.
