Rescanning may be appropriate after this but may not be necessary. Pick 4 or more of your grid points spanning the area of your map (at least the 4 corners) and when you open it in MapInfo choose to register the image and use the values of the points you have laid out on your map. Non-earth would be your projection. And you should be set to go. Second scenario: If you have a few points and you know the projection, especially if it is state plane, you should be able to carefully, manually obtain and place on your paper map points with coordinates appropriate for registering your scan. You want at least the 4 corners and the more the better. use these points to register your scan when you open it in Mapinfo choosing the projection and units you know to be correct. Nothing on the scanned map will have coordinates as vector objects within MI unless you then digitize those objects on-screen. However, any work that you then do will be within the coordinate system you have set up. This is a standard way to work. YThe more and accurate points you use the better. The only significant pitfall is the panning/screen redraw/object location BUG within MapInfo which they dont seem to want to address.
