I hope you aren't running pictures through the scanner before developing them...
and honestly, if you're not developing your own film, just have them scanned when they are developed. They probably have a better scanner and they'll just dump the pics on a CD for you.
Honestly people's images I've seen that have done this were horrible, horrible quality. If you don't have access to a good scanner meant for things like scanning negs and photos then it's your only choice, but if at all possible avoid doing this. And honestly there's not any really convincing reason to scan negs for output, just print wet if you shoot film. If you want to output digitally shoot digitally.
Edit:

in my film days I used
this. Wonderful, wonderful camera.
