Canoscan 8400F problem

The first problem I had with my scanner was when I scanned a document the resulting image was totally black. I phoned Canon help and they told me to disconnect my web cam, I did this & I also change the UBS plug in position. Now when I scan a document I get a vertical rainbow image or again a totally black image

If possible, try it on another computer. If the symptom is the same, then the scanner requires service.

    To add to my previous suggestion, make sure the scanning unit is unlocked. This will be a switch either on the bottom of the scanner...or underneath the scanner lid.

Can I scan a negative 4X5 black\white to make a photo

In general, yes, you can scan a negative and make a photo from it. I don't really know your model scanner, my Canon 8400f has a film adapter and a light in the cover, but would have to scan a 4x5 in sections and I would have to piece it together after scanning.
The results I get from scanning negs are very good, as good as I ever got in my darkroom.

I want to save scanned document as a .doc using CanoScan 8400F

Scanners only see millions of dots. Unless it has software to convert a picture into a document, all documents are seen by scanners as pictures made of of millions of dots. Software is available to convert it to a Microsoft Doc format but it is very expensive.

Scanning documents for report cards

It will scan pdfs but you would need adobe professional to add the data for each student. It cannot scan a document and make it into a Word doc because this is essentially an image scanner and .doc files, etc. have more complex embedded information that cannot be captured by a scanner because that information is not visually present (i.e. exact font size, type, formulas, etc.). You'll have to find some other way- sorry!
