Installed an Epson XP-305 all in one about three months ago and it has worked fine until I tried to use the scanner today on my Acer desktop. Not something I use often so it may have been down for a while.
Whichever host I use it is listed in select source, but when I try to use it there is a failed to detect message.
Also the WIA option is missing from the select source option.
This device is also installed on my laptop. (Both connect by wifi) and it works fine from there.(WIA is there on the laptop) On investigation the IP address was missing on the desktop settings so this was copied from the laptop. Still no good and I'm now stuck.
I'm reluctant to reinstall because I think this problem lies with Windows and not the scanner driver because of the missing WIA.
The printer part works fine.
