Check your scanner's instructions manual...

Yeah ask me I have a flat bed epson scanner. That is if you
have one.

...Well, no one CAN help you, because you haven't given us
enough information in order to help your properly.

First of all, make sure that your computer can
communicate with your scanner. Usually, there's an option
that allows you to do this.

Is the scanner not
scanning at all, or is the image just not showing up? Be
more descriptive.
