Waterfall 2 pockets

English to Italian Tech/Engineering Electronics / Elect Eng Printer/scanner screeen message

Hi,

I am translating the message texts to appear on the screen of a canon printer/fax/scanner machine and one of the strings is:

Waterfall 2 pockets

I have no references (images, glossary, etc).
I am not sure of the word order wither:

2 tasche cascata?
Tasche 2 cascata?
Tasche cascata 2?

Grazie per l'aiuto!
