Russell Hobbs filter, cappuccino, exp...

I was recently given a Russell Hobbs combination filter, cappuccino and expresso coffee maker without a manual.

I understand how to make filter coffee, but do not understand why the filter container only allows you to put a maximum of 6 scoops of coffee at a time. One scoop of coffe per 100ml of water yields 3 average cups of coffee. The coffee jug is huge, how do I overcome the problem of making coffee for more than 3 people at a time?

Question 2
I cannot figure out where I pour the water into to make expresso/cappuccino. I fill the steamer chamber with water then add 2 scoops of coffee into the filter chamber - this is the maximum amount it will allow me to put in at one time - then I lock the filter chamber into position.

My question to you is : Where does the water come from that drips into the glass recepticle under the filter chamber ? There is a picture indicating a whoosh of steam and the qty that it holds being 2 or 4 on this small glass recepticle.
