Where can I find a scanner?

Go to a computer service shop on the street and scan there.

Or buy your own scanner. You can buy it in general computer city. If there is no computer city around, go to the store where you buy computers and ask.

As long as there is a place to buy a computer. Generally in cities above the county level. Generally, there are computer stores in county towns, and some towns also have (several). I suggest you just ask someone familiar with you. You can also ask passers-by when you get to the county seat. You can ask where there is a computer in the county, because I don't know where the computer shop in your city is.
