Hi community,
Facing a problem with WC6515 WiFi scanner
When I want to scan from flatbet in b&w, I get a message (translation from french): "fail to communicate with device via HTTP. See you administrator.." and scan doesn't start.
Printer service is working.
Sameone faces this error message? Any clues on that?
Regards,
