You could try;
but I didn't see a MFC3240C so I woud suggest that you look at sommme of the others.
I presume that MFC stands for Multi-function color and I fear that your search may be long and hard.
But don't give up - I have a Konica-Minolta Magicolor 2300DL which uses foo2zjs driver and an ICM from an extraction of a Windows exe file - weird but it works, on all my vmware linux guests - as listed under my name (left side) using CUPS and ghostscript and the interface is an IP address on my LAN.
Sorry I can't be more help
