I too have an ir3300 and was having issues with faxes. I found this
googleing:

Hooper:
IR330 w/ print and fax works just fine. Except that it does      not
receive from one customer. May I add that it's their most important
customer! The faxes are coming from a computer. 

I have looked at my past note on a similar problem and did this: 

SSW3 1000-0010 from 0000-0000 
SSW17 0000-0010 from 0000-0000 

MEM 
NL to on from off 
ATT to 6 

NUM 
02 to 15 
03 to 20 
04 to 15 
010 to 6800 

Not sure of the rom versions. 

Still isn't receiving. Any suggestions?

Try 
setting SW05 bit 3 to 1 from 0 

I have seen this same fault with the HP31xx 

      
Hooper:
Problem fixed! Changed SSW5 bit three to 1 from zero.

I only changed the ssw5 bit.... the other changes seemed to make it
worse.

Hope this helps!
