This Canon scanner was purchased Monday, September 21, 2015. Why does Canon implement pay for technical advice, via the internet, no less, on newly purchased products? Does this imply a lack of confidence with this scanner? I am considering returning it as an unsatisfied customer. I researched this product and the reviews are favorable, so why can I not scan???

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

To clarify that error message, first of all: it means, "either the scanner is Off, OR the USB cable connection isn't there."

It's possible that you simply have a USB cable that is defective or has gone bad. And make sure it is plugged in at both ends (and switch it to a different USB port on your computer.)

To clarify: This is We do provide advice for Canon products, but are not an affiliate in any way to Canon.

If the scanner was recently purchased and re-seating the USB cable at both ends, trying a new/different USB port, and trying a different USB cable, all don't change the error message, then you should indeed return it promptly to the vendor or store for a refund or an exchange for another... if the return-exchange period of your vendor or store has not expired already.

If it has expired already, then you may require Canon to fix the problem for free, under warranty terms.
