Canon MF Scan Utility and MF733cdw

[mokotoy]

Installed Canon MF Scan Utility on my MacBook Pro (OS X El Capitan) 

It won't scan consistently. It would continuously throw an error:

Cannot communicate with the scanner.
The cable may be disconnected, or the scanner may be turned off.
Check the scanner status and try again.
Scanner driver will be terminated.

Error code: 600007

Cannot communicate with the scanner.
The cable may be disconnected, or the scanner may be turned off.
Check the scanner status and try again.
Scanner driver will be terminated.

Error code: 600104

Cannot scan because of the following:

- Scanner is busy
- Error occurred in the scanner
- Scanner is in Sleep mode

Check the scanner status and try again.
Scanner driver will be terminated.

Error code: 2100009

I would get varying errors. I ensure that the printer is awake and the scanner is ready. 

I'm ablet to print ok, and scan via email ok. Something is preventing the connection between the utility and the printer. 

please help!
