Brother LT5400 500-Sheet Paper Tray Printer Accessory - Black | High-Capacity Paper Feeder for Office & Home Printing | Compatible with Brother Printers

Installation was very simple, just place printer on top of the paper tray (there are obvious plastic posts to guide you and securely place the printer on top). Printer is bulky and a decent weight so please make sure you are comfortable lifting the printer. Had to turn off and on the printer for it to recognize the new tray. Used the printer menu to set up one tray for Legal and the new tray for Letter size paper. I also used the device manager on the computer to make sure the settings for the trays (default settings) were correct. Everything worked well and the product works as designed!
