Bump up your Brother printer's paper capacity with this additional paper tray. The unit can be used with both the HL-1650 or HL-1670N printer models and will add 250 sheets to the printer's already generous 350-sheet paper capacity, helping you fly through high-volume copy jobs without the arduous task of reloading. The paper deck can accommodate a variety of paper sizes including letter, legal, executive, A4, A5, A6, B5, and B6, plus envelopes.
