I got Canon MX-492 and installed the latest firmware, drivers, and utility software. I could make print and access to the embedded Web server (EWS) work. However, I had to spend several days to make scan work.
After doing the following steps, scan started to work .
1. Wi-Fi connecton was enabled by using WPS button on the router. Although I wanted to use the Standard method for Wi-Fi connection as it is used by all of our other devices, entering a password by using the console of MX-492 is very difficult.
2. I removed the password for the administrator of the EWS by selecting Security on its home page The default administrator name is "ADMIN" and the default password was "canon".
3.I tried to perform scan by using IJ Scan Utility, but it failed. Therefore, I activated it by using Canon Quick Menu by going to
Start at lower left of Desktop > C > Canon Utilities > Quick Menu > Canon Quick Menu > Scan > Auto or Photo or ...
You may try these steps in reverse order as I do not know which step is crucial. If anyone finds the fundamental cause of the problem, let me know.
The error message when I use IJ Scan Utility is
-- Scanner is turned off.
-- USB cable is disconnedted.
However, it is easy to see that scanner is turned on from the green power-on light.
Further, I am using Wi-Fi connection and the USB cable is not used. Even when the USB cable is used, IP Scan Utility fails.
What is the error code that appears at the bottom of the error message when you attempt to scan using the IJ Scan Utility?
