Printer Pixma G7050: Cannot communicate with scanner. Code: 5,156,69



I have bought the printer Pixma G7050. After install the driver I have tested the test page. Everything is ok.

Then I started the Canon IJ Scan Utility. I clicked the icon <Document> in order to scan one document. I got the error message "Cannot communicate with scanner. Possible reasons: Scanner ist turned off, USC Cable is disconnected".

The error message is untrue because I have tested the test page sucessfully. I read a lot messages posted with the same error message. Just to clearify: I deinstalled the Software, installed it again and restared the window (Window operation system; WIN 11). I am really frustrated as I spent a half working day on it. If you knew the common problem with this product, I will never buy the canon product. 

I hope that somebody can help me to solve this problem.

Thanks a lot.



also have problem with pixma g7020.

When scanning, it will go to a red error saying loss of communications. Turning off vpn and anti-virus do not help. Microsoft WIA driver (with less capability) does not have this problem.
