  2. Chaised around this issue for an hour before stumbling across this website after already removing / reinstalling software.

    Perhaps it was removing it from the registry that did the trick.

    Thanks!

  3. I've tried all this and my paperweight - I mean scanjet 3970 - still won't work. It's about time to trash it.

  4. Man, I can't tell you how nice it was to finally have this problem solved. We've got an officejet 6110xi and started with the HP Director problem after an IE upgrade. Once that was solved, we had the scanning error. I went through your instructions step by step and after unchecking the "compatibility", the HP Director now scans!! Thank you so much for posting this.

  5. Ans, you are the Master. If you are from HP then I am surprised. I tried talking with HP, I tried to uninstall the software, and then do a re-install. Those did not work. You took a lot of stress off me. Thank you.

    I will make your solution searchable to all owners of HP imaging devices experiencing problems like these. Keywords: HP Photosmart C4280 C4200 All-in-one imaging device Unexpected internal error

  7. I've done all this MULTIPLE TIMES with my older Scanjet 3570cxi,but still no go. The scanner worked before I re-installed Windows XP on my new hard drive, it also works on my laptop. The problem is somewhere in the Scan Director, because I can get the scan program to run when I run it directly from the bin directory.

  9. I have the same scanner and exactly the same problem as anonymous (dated May 3, 2009).

    None of these solutions works.

    I have re-installed drivers and software, edited the registry, installed every patch I could find on the HP website, and on and on, to no avail.

  21. Fantastic. I've been having these problems ever since I upgraded my computer and have had to rely on somebody else in the office doing my scans for me. I have deleted and reinstalled more times that I can remember, nothing works. I have followed your instructions to the letter and it works!! What actually fixed mine was your suggestion to delete the entry from the registry - now all perfect. Thank you so much.

  22. Thanks, I downloaded the patch and it fixed the problem - printing and copying was fine, but kept getting the "An error occurred communicating with the scanning device. Please ensure that the scanning device is connected properly and try again." message after installing a new ADSL2 modem.
