printer scan problem

I have a Dell 960 printer. When I try to scan a document using MS Word the scan goes through fine if I go to "how will the scan be used" in the Dell all in One Center and highlight this:

 

To be printed (scan at 150 DPI)

 

But if I hightlight this so that I can edit document once it's scanned:

 

To edi text (OCR + 300 DPI)

 

the end result is reduced in size and barely readable. It is fragmented also. I am able to make corrections though

 

I receive a window that sez "some images have suspicious resolution"  and offers me the following choices:

               leave original

               overwrite to 300DPI

 

the document I'm trying to scan is a text only page.

 

Any idea what I can do to scan a document into MS Word and have it come out normally, and be able to to make changes?
