1. How old?
2. What make, model?
3. Does it work on other machines?
4. Would you like a free scanner?
The answer to number 4 is to look in the free area of craigslist and watch freecycle (see google.com)
I find that often now , when I scan, I
am getting two vertical columns.. one
each side... kind of "interference "
could this be my scanner getting old ?
then sometimes I get perfect results.
