HP Officejet Pro 7440 - Not allowing A3 printing

[DeaconMarriner]

I am trying to print A3, so I had A3 paper in tray 2, but this tray is showing up as a photo tray on all the settings, even though I have set it to A3 on the printer and on the app.

So it won't allow me to print to that tray as it thinks it is a photo tray and the size options are limited.

Then I put A3 paper into tray 1, and that doesn't work either?
