My Epson Stylus 435W has suddenly decided not to scan. It prints ok, the cartridges are all renewed. I contacted Epson , but they just directed me to their Q & A pages - not much help.
The error message states "communication error", which can't be right, as I can print OK .I have re-installed printer, but still no joy.
After using Uninstall in control Panel, it leaves files on your PC that is where knowing what and how to look for comes in, so that you can delete them. as one file may have got the configurations on it, this is the one that needs removing as also Regedit will have settings in it, though you uninstalled these need to be removed before reloading drivers. Scanner Driver is different driver to Printer Driver. Name of Scanner Drivers are called Twain Drivers
OK. So you've tried everything obvious.
What OS are you using? Try this:-
Turn off the device and disconnect it from the computer
Uninstall everything relating to that device.
Reconnect the device
Restart the computer.
The computer should come up with something like "unknown device" and then give you the option of installing the new software for it.
