I need help, I installed the Pixma E402 to a new PC with Windows 10 and when I try to use the scaner I get the, saying the printer is not connected or turn off; but that it is connected (it prints just fine). I don't have that problem with my very old laptop. I turn off the firewall with no success either (McAfee).
This error usually occurs if a firewall or anti-spyware program is blocking communication to the scanner. If the error remains after you have disabled this software, you may have to add exceptions for the TCP and UDP ports which are used by the printer. Visit THIS LINK for details about what ports are used. Contact the manufacturer of the firewall software for assistance with adjusting the settings in their software.
Please try disabling your security software and then attempting to scan again using the IJ Scan Utility.
