I have a HP 4000n printer and want it to print from tray 3 when tray 2 is empty. It doesn't do that now.
I don't have a 4000n, but I do have a 4200n that should be relatively similar. On the 4200n you can change this behavior by going to the menu, then Configure Device->System Setup->Tray Behavior->Use Requested Tray, then setting that value to First. My guess is you have that setting on your 4000n set to Exclusively, which will then prevent the job from going to a different tray. It also requires that you have the same type and size of paper registered in both trays if you want the job to automatically switch over.
If that menu path is different on your 4000n you just need to dig around in that menu to find the tray behavior setting.
