I have a Dell A940. I cannot scan multiple pages. Sometimes it will go thru the operation of scanning but the final result is unreadable. It comes out as squares and signs rather than letters and numbers for example. At other times it will only print the first page and does not offer me an opportunity to print any subsequent pages. This single page it does give me is perfect. I follow the instructions in the owners manual and it still does not give me multiple pages that are readable. Can any one help. So far I keep getting from Dell Tech Support the same instructions that are in the owners manual.
