Thanks for your help, honesty and reply.
To put it in context - I am a cardiac surgeon with a very small office looking after our private practice. Lets say less than 5 people. After using Lexmark and Brother for years with many difficulties I was recommended the Xerox WorkCentre. It was great and easy to configure for anyone to press Scan To and then enter. It automatically scanned using our presets to the network folder. (there is a server and 2 NAS - it is fairly safe and secure). I was so pleased comparing with our previous MFP's that I ordered the Versalink believing that the apps based control would be a further improvement. We did not definitely need an upgrade at that point.
I was disappointed that it was more difficult to set up the features we required, and online help did not answer our questions. Previously we could set up a workflow whereby an adminstrative assistant presed ScanTo and then the default folder on the network appeared and she pressed enter and it was scanned with our preset defaults.
Something significant has changed here and it is interesting to learn of your conjecture. I will remain interested in that, and if you can feed these thoughts back somehow to Xerox that might be useful.
Thanks once again for providing some excellent information. You also helped me with scan to email in a separate thread, and that's been extremely helpfull. I will be interested to learn of developments for VersaLInk and AltaLInk..
