When your printer has a Lower Tray Assembly, you can easily run large jobs without having to replace media often.

1. For automatic tray switching to work properly, load the same type and size media in all of the printer's media trays. The media trays must also be of the same type (e.g., Paper). You can also use the Multi-Purpose Tray for automatic tray switching; fill it with the same media type as the paper trays.
2. Install a tray in each of the printer's tray slots. If you have the Duplex Unit installed in the printer's upper slot, install the media trays in the middle and lower tray slots.
