OK - Decided to restore my system prior to before I attempted to install the MFP. This time no error messages about PCL during install and everything seemed to go smoothly. I have not attempted the "Install Scanner Twain
Driver" as this initially asks for an IP address which unless my basic knowledge is correct has no relevance to a printer which is connected locally by USB.
If I am wrong please let me know.
Now I want to be able to scan multiple pages to a multi page pdf file. There is a utility that comes with the MFP called "ActKey". When I select the folder option for scanning too I get the message
"Please check that the device is set to remote PC mode".
I have looked through all the settings on the MFP and can't find any option like this so now I am stuck.
