Changing Tray Paper Settings
In the [Media] hub, or on the [Tray Status] tile in the [Home] hub, assign a Custom Paper to a tray. You can also assign a paper type or paper weight individually to a tray on the [Tray Status] tile in the [Home] hub.
When you are finished specifying the paper settings, load the paper of the specified size and type onto the tray.

If the specified size differs from the actual size of the paper loaded in the paper tray, a misfeed might occur because the correct paper size is not detected.
If the specified paper type differs from the actual type of paper that is loaded in the paper tray, the paper might misfeed, the toner might not fuse properly, or the print quality might be reduced.
Paper that can be specified on a tray varies depending on the tray. You cannot specify paper that is not supported on the tray.
