I had the same problem and was having no luck with suggested solutions from HP. But the following procedure did work for me. It disables WIA, the built in XP scanning software. See http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1280600613997+28353475&threadId=124494

1. Right click My Computer.
2. Click Manage.
3. On the left, click the plus sign on Services and Applications.
4. Double click Services.
5. On the right side, scroll down to Windows Image Acquisition (WIA) and right
click.
6. Click Properties.
7. On the General tab, set Startup Type to Disabled.
8. Click OK.
9. Exit Computer Management.

Yes! No WIA, no scanning! It means Windows Image Aquisition is not turned on... Not only will the scanner not work but also other Imaging devices like cameras. The best way to find out will be to try and scan from Microsoft Paint. Go to Start, all programs, accessories then look for paint. When paint opens, click file then from scanners or cameras. Try to scan, if it scans then WIA is ok.
It means is the scanner software that was not installed correctly so uninstall reinstall just the scanner software! If Paint does not scan, then its your computer's Operating system (winxp) at fault. Make sure WIA is started, or better try to restart that service (in control panel, administrative tools, services, look for Windows Image Aquisition, restart the service).

Normally, If you are running Windows XP, the Built-In Internet Connection Firewall (ICF) maybe enable without your knowledge. This is the default setting of Windows to protect your PC from hacking. However, of course, this default setting may block you from running some applications you might need to use like Viewing WebCam in Yahoo! Messenger. Anyway, there is always a way to solve the problem.

Below are the steps to enable you to veiw WebCam by instructing you to ensure that the correct ports are opened.

1. Click Start, Settings, and select Control Panel.
2. Double click on the Network Connections icon.
3. Right click the connection that you use to connect to the Internet, and then click on Properties.
4. On the Advanced tab, uncheck the box Protect my computer… if you would like to disable the firewall. If you like to only open the webcam ports, check the box and continue with the remaining steps.
5. Click the Settings button.
6. Click the Add button.
7. Under Description… fill in Yahoo! Webcam. Under Name or IP… fill in 127.0.0.1. Under both External Port and Internal Port fill in 5100. Check the button TCP.
8. Click OK to close all opened dialog boxes.
Work done! I guess now You can view webcam in Yahoo! Messenger
