Adobe 9 Black on White Document Scans to PDF Invert Black to White and vice versa! Not Good!

Question

I have the same problem as TexasLawyer (Jul 30 2009) whose question was not answered nor was there any answer to a commenter who said he has the same problem ("I have an old HP LaserJet 3330 multifunction printer, and prefer scanning documents out of Adobe Acrobat rather than the software that came with the scanner.  However, after upgrading to Acrobat 9 Professional, the scans result in negative images.  I tried using the option in Acrobat to create negative images, hoping that that would result in a positive, but it didn't work. I'm using Windows XP, also.")
Me too. Except I am running XP as a virtual machine in a MAC (Snow Leopard). I "upgraded" to Acrobat 9 from a functioning Acrobat  6 (worked fine with my setup to make correct B&W pdf's from scanned B&W documents on the HP 3330 before I installed Adobe 9--I got updates immediately and am at version 9.1.3) butthe  Acrobat 9.1.3 scans on the HP 3300 invert white to black and black to white. The printer option box to invert black and white images was unchecked.  I checked it and ran the scan again but same result--white of paper document is black in pdf and black is white in pdf. I can scan the B on W document using grayscale and get B on W but the file is too large and unacceptable due to smudges picked up with gray scale.
Can't understand how so basic a use of Adobe is this messed up.This has to be a common problem since many many users scan black on white documents to pdf. Does anyone have a solution to this? It is critical in my profession.
Thanks in advance to you problem solvers out there that can solve this for me and hte others in my boat who search these forums looking for the answer to this issue.

Answer 1

I have an HP6010 scanner (sheet feed) that is used to scan multiple page documents. If I use the WIA scanner option I cannot select page size and the scanner defaults to legal size. On the other hand if I use the Twain driver I get negative images on my scans. I just installed Acrobat X Pro and the same thing is happening. I was using Acrobat 9. In fact in duplex mode the scanner outputs a negative image every other page, and a standard image on the alternate pages. Either way I am frustrated. I can't remember when the problem began, but I believe I was running XP SP2 and Acrobat 7 or 8.
Ironically, if I push the scan to PDF button on the scanner, which uses an HP utility, it comes out fine. All pages are in positive mode.
I did try scanning in color even though the document is black and white. I believe that the scan was fine. No negative images, but scanning in color is like watching the sun go down.
I thought it was Vista and System 7, then I was told that it had to be a scanner issue and that I needed to talk to HP. However, if the scanner functions properly on its own, with the HP utilities, then it has to be Acrobat.
