The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

"Unable to communicate with TWAIN device" with non-HP scanner after installing HP scanner

Asked by whitney178 in Computer Scanners by General

Tags: , , ,

I have been using a Canon MP730 scanner successfully on my Windows XP Pro system for some time with a variety of application software, including PaperPort 9, Adobe Photoshop and ABBYY Finereader.  After I installed an HP 5500c scanner, both Paperport and Finereader report "Unable to communicate with TWAIN device" when trying to use the Canon scanner;  Photoshop, on the other hand, still works fine with the Canon scanner.  I uninstalled the HP scanner, but this did not cure the probleml.  Uninstalling and re-installing the Canon driver and Paperport did nothing to affect the problem.  This problem is apparently not new -- for example, a message from Don Burklo at http://www.computerbanter.com/q-t_46004-PaperPort-Software.html indicates he has observed this same behaviour with other non-HP scanners after installing an HP scanner. Additionally, a writer by the name of Harry states
 "The error message "Unable to communicate with the TWAIN device" when trying
to scan with PaperPort is a known issue. In most cases it is caused by
scanning with PaperPort using an HP scanner and then trying to use another
brand of scanner. I have been unable to scan with my Brother for many
months now. The problem is a ScanSoft issue, as this only occurs with
PaperPort and OmniPage."
In my case the issue also occurs with FineReader. so it is not confined to Scansoft applications.  It appears that the HP drivers are somehow corrupting things so that at least some programs are subsequently unable to communicate with non-HP scanners.  A solution to this problem would be most appreciated.      Start Free Trial
