Canon IR 3045

hi all,
at work we have a multifunction system (Canon IR3045) connected via network (static IP) - I am using the printer functions with no problem (using the posted linux drivers, and also the BrightQ suite which is great) but I have problems accesing the scanner functions -
I have followed all directions on posted wikis/forums on how to enable the network scanning option in sane but nothing seems to work - the multifunction system is not connected to a PC - it has it’s own static IP address

when I use yast to find the scanner it is not detected and it prompts me to check for firewall settings (I believe are fine since the printer is working, and tried to add the specific scanner port but it didn’t make any change)

any ideas?
