Good day We have ordered an additional paper tray (https://www.digitec.ch/de/s1/product/oki-2-papierschacht-fuer-535-blatt-drucker-zubehoer-5634774) and the rollable base cabinet (https://www.digitec.ch/de/s1/product/oki-rollbarer-unterschrank-45893702-drucker-zubehoer-5832144) for this product. Is it possible to add a third paper tray (i.e. a second A4 tray) to this model, or is this only possible with the MC853dnv and MC853dnct?
