Can I reinstall without losing all my filessettings etc I really dont want to have to go down that path if I can avoid it.

Epson Wf-4630 Software Will See

Epson own scanner software will see and use the scanner but not the native OS X software.

I need this as I use some PDF OCR software, as the poor Epson software fails to OCR the PDF files it generates.

I connect the XP-760 printerscanner via Wi-Fi but the same occurs even if connected by Ethernet.

Delete any software relating to the printerscanner you installed.

In Finder select your hard drive and go to Library - Printers - PPDs - Contents - Resources and delete the files for your printer.

Also look under Library - Image Capture - Devices and delete your scanner.

Now reboot you Mac but enter recovery mode (Command R) and use the option to re-install Sierra.

Once complete and you are logged back shut down and perform a NVRAM (PRAM) reset and a SMC reset.

Epson Wf-4630 Drivers From Apple

It will take longer than normal as it will need to download the drivers from Apple.

Mine needed one extra re-boot before it sprung back into life.

I know how critical it is to be able to scan and print in a reliable manner from your Mac.

This also occurs on my 6 month old MacBook 11 but does not happen on my Wifes MacBook Pro that is still on Yosemite, so it looks like Apple has some work to do fixing the Epson scan driver.

Apple need to fix this, because adding an identical printer shouldnt warrant having to re-install the OS).

Now, again with my Mac and an Epson printer (weirdest part - on both occasions it was working fine until it wasnt).

I deleted the Epson apps that I had installed and that did the trick for me.
