HP: The software had trouble scanning or was cancelled.

So your HP scanner stopped working?

 

When trying to scan, many HP multi-function printers, such as the M2727, M1522, etc. have a problem that pops up and says:

 

The software had trouble scanning or was cancelled.

 

 

Here is the fix: 

• Uninstall the printer.
• Run Regedit
• Make a back up of your registry.
• Do a search (include keys/values/data) for the description of your printer, e.g., Hit F3, then search for M2727.
• Delete all HP-related registry entries that have that printer listed.
• Reboot
• Reinstall the printer software.

That should do it for you.
