One optional lower tray (Tray 2) can be installed, and the lower tray can hold up to 500 sheets of 80 g/m2 (20 lb) paper. When the optional tray is installed, the printer can hold up to 800 sheets of plain 80 g/m2 (20 lb) paper. If you want to buy the optional lower tray unit, call the dealer you bought the printer from or Brother Customer Service.
For setup, see the User's Guide that we have supplied with the lower tray unit.
