When you're scanning a document, have you tried different options?  I'm trying to figure out if the scanner is operating correctly.

 

Can you place a document on the flatbed and through the CanoScan toolbox software click Copy to send it to the printer?  Does that work?

 

Are you able to scan a document and save it as a PDF file using the toolbox feature?

 

Sometimes the Canon scanners will malfunction and give you strange error codes. Let me know if either of those "tests" is successful.

Thanks txtchr I did edit post to say I had sorted this problem.

I uninstalled and reinstalled twice before it worked properly no idea why it should start playing up

but its ok now once again thank you for your reply

Glad you got it worked out.  When I investigated your problem on the Canon website, I found that they suggested you reinstall the CanoScan toolbox (or an updated version that they have available on their website here).  :)

Thanks will take a look

Contacted Canon by email on a Saturday night. Sunday morning has the fix to the problem.  Their response email:

Apparently I had deleted the file specified in the "Settings" window.  I changed this and everythings fine.  Great service & response.
