Hello [Anonymous]
1 pc. LT-330CL additional paper tray with 250 sheets should be safe, see specifications on brother.ch - Consumables and accessories - Accessories here: https://www.brother.ch/de-ch...
According to brpther.de a maximum of 3 of these additional paper trays are possible, maybe 1x Scubalde with the machine + 2xLT-330CL? here: https://www.brother.de/drucker...
Greetings

I do not think

Don't have that need, don't know. Ask Brother.
