With an input capacity of 250 sheets, this optional paper tray can help save time while providing flexible media support. Workgroups can increase their productivity by reducing time-consuming tray refills. Add the LT-5500 to a compatible model to automatically print on letter- or legal-sized paper without having to manually load paper trays for mixed paper sized documents. Add up to three trays to the HL-L6250DW/6400DW, up to two trays to MFC-L6750DW/6900DW and one tray to HL-L6400DWT.
