HP Envy 7880 insists I have 5x7 photo paper loaded, when in fact I have 4x6 paper loaded.

My HP Envy 7880 insists I have 5x7 photo paper loaded, when in fact I have 4x6 paper loaded. The sliders are tight to the paper. After I push the tray back in, it says I have 5x7 paper loaded, and the option is "grayed out" so I cannot change it.

How can I get the printer to recognize the size of the paper that is loaded?

I can't get it to work from windows 10 nor from the iPhone.

Welcome to the HP support community.

Perform a power reset

1. Turn on the printer, 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. Wait at least 30 seconds.
5. Plug back the power cable straight to a wall outlet and printer without any surge protector.
6. Turn on the printer.
