update:
I thought that the head was blocked, and it seems that it was..
so I put it on the correct position, but the usb notifies me just for
a sec that I have it plugged and I get hardware malfucntion error
sign... I tried aligning slowly the motor but I cant never get that
normal USB found new hardware msg... so, anyone has an idea how to get
it work?

thanls

If your Canon is like my Canon, I would release the lock on the
bottom of the device

ano ano... but thats not the problem... it just frozen while
scanning.. seems that the head got blocked, but when I unblocked it,
usb wont find it anymore...
it finds it only when I scroll it a bit faster on an certain point of
the motor, buit when I try to scroll it normally so I get the normal
head position, nothing happens :s

any ideas welcome..

Buy a new one! Sorry to be blunt, but scanners are often cheap to buy and
built with with non-serviceable electronics like custom ICs etc. Unless this
is a high-end professional scanner, I'd start looking for a new one.

If you're handy at electronics, then by all means do some basic
testing/troubleshooting inside, you may get lucky and find something easy to
fix.

I'd check the ribbon cable to the scan head first, they can go open circuit
for obvious reasons.

sure, np...
well, as hard u may see this, in my country its hard to find scanners
ranging from 600x1,200dpi cheaper than 100-150bucks, and since Im a
student which depends from a limited money, hard to get it :s

ill try to check ribbon cable... and do some work after to see...
thanks anyway
