I have the MF Scan Utility on my PC. I have uninstalled and reinstalled it mulitple times. I cannot scan from the printer to my PC nor can i start a scan from my PC. I can print fine so I know its not a network issue. I was able to scan fine for the last several months and it quit working a few weeks ago. Any clue or assistance.
Same problem as the others. Sometimes, pulling the plug and rebooting the printer will let me scan one page, but then the error message 155,0,0 returns. It seems obvious Canon has a coding problem with the Scan Utility that was updated in 2019, but won't admit it. As my machine is now out of expensive toner, it is headed from ebay with a warning. Glad I found out it is junk before investing more in toner!
I have been having this exact issue for weeks. I have re-installed everying including the scanner driver. It worked one time and then quit. Now I am getting a different message:
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 terminted.
The scanner is not off and I can print with no issues. I just can't scan. I have tried calling Support and was on hold for 18 minutes yesterday and no one ever answered. I am very frustrated and need a resolution to this problem. Any help you can offer would be greatly appreciated.
