I am using canon MF4360-MF4390 Printer/Scanner/Fax through network, it works fine with printing but how to scan ?

I don't see your Canon device on the Apple list of supported devices - http://support.apple.com/kb/HT3669#canon.

I have a PIXMA MG8120 and it's supported with both print and scan.

I did find this link - http://www.hamrick.com/vuescan/canon_mf4360.html - which seems to be a driver for scanning.

Try contacting Canon - I've found that their customer support is terrific. There may not be a driver that will work... is this an older device or a new one?

You most likely need this driver:
