Thanks for your prompt reply ReaperX7, I think the problem lies on my end. After modifying BIOS settings, It seems that my mobo won't change parport modes effectively into EPP, EPP or ECP+EPP and since the EPP is required in order to work with this scanner then I'll need to try It on an older mobo.
After checking with a script from: http://umax1220p.sourceforge.net/trouble.html
S01: parport built as module
S02: ADDR :0x378
S02: IRQ :5
S02: DMA :1
S03: parport parameters are: /sbin/modprobe -q parport_pc 2> /dev/null
S10: ppdev built as module
S12: /dev/parport0 exists ...
S12: /dev/parport0 is readable ...
S12: /dev/parport0 is writable ...
S12: do you want to allow any user to access ppdev ? (yes/no)
S12: mode changed ...
successfull end ....

The available options on the BIOS setup are Default,EPP,ECP, EPP+ECP, and won't let change them from IO=378h, IRQ=5, DMA=1
