The scanner is not working. I keep getting an error saying that the Scanner is turned off and the USB is disconnected. Neither are true. The printing function works and it's connected by a USB cable. I've tried multiple USB ports, I've deleted extra folders in the TWAIN_32 folder besides the MX390 Series folder. and the wiatwain.ds file. I am running Windows 7. Thanks for any suggestions.

I ran into the same problem. Occurred on windows, occurred on Mac. Occurred irrespective of operating system version.
In windows the scanner showed up in the device manager and I could see it disappear when I unplugged the scanner.
Strangely enough what worked for me is using a different USB cable. I went from using the one that came with the scanner to another one I had laying around. Then things worked fine.

I have this problem too and it's recurrent.
Yesterday I spent 40 minutes on the phone with Canon - they got me to turn the printer off and on then off and on, press the black button to do a test copy, and so fourth..
he got it scanning again, but if I unplug the printer to put it away, and get it out to use it again, the same problem happens again
so today I turned the laptop on and brought the laptop into the room I'm working in and it's happening again 😞

Hi LadyBev59,
The 5,156,69 error can be caused by security software that is enabled on your computer.
Do you have Norton, McAfee or Webroot installed on your computer?

no i have TotalAV

Please try disabling that software and then attempting to scan again.

I'm having this problem as well - Pixma MG5750, running Win 10 with Avast antivirus running. I disabled Avast temporarily basd on advice in this post and had no results. Printing is fine, it's purely scanning which is one of the main reasons I bought this model. I even went and hunted up the USB cable and plugged that in. Still unable to scan. Please help?
