The TT-4000 tower tray option includes four 520-sheet capacity trays and a stabilizer with wheels. Add the TT-4000 to a compatible model to automatically print on letter or legal-sized paper without having to manually load paper trays for printing mixed paper sized documents. This option is ideal for high-volume, large work groups that need multiple trays to customize their workflow such as storing different media in each tray or for additional input capacity.
