I've just replaced my computer and now can't use the scanner function on my printer (Epson WF 2630). It prints OK using wifi so the wifi network is working. I've downloaded Epson scan which worked really well on my old computer but when I try to use it now it claims it can't communicate with the scanner and to make sure it's properly connected, turned on etc. I can't find any settings in windows that seem relevant and I think all the drivers are current as the scanner worked with my previous computer. What can I do?
