Error Code 5 156 69

[bmijgoodrich]

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 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?

[LadyBev59]

no i have TotalAV

[Patrick]

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?

My operating system is Windows 10.

Using Control panel I deleted all the Canon Printer.

Then plugged the printer into the mains and connected USB to Laptop.

It install a new driver by itself and the scan just work again
