I don't know of a printer that doesn't do exactly what you are stating, which means it is very much how it is intended to work, and it is not considered by Xerox (at least Xerox Engineering) to be broken.
So your only option is to contact Xerox and ask them to do a FER (Feature Enhancement Request)
It isn't guaranteed by any means they will do it though, so it is better if you can find a competitive model that does do what you want , because if there is a competitor in the market, it will be more likely to sway them into developing it.
Edit: I discovered that the older generation Discovery Controller machines do indeed do what you want, so if you can't find a competitors machine that does it, you can add that the Xerox 7556 for example could do it. But it has more sway when the model is Canon/Konica etc than a Xerox.
We are facing issue with altalink c8055 scan to email file name option.
Whenever we rename scan to email file name example:testscan 06.12.18 it comes with testscan 06_12_18
Everytime i have to rename the file after scanning and is there any solution for this issue.
Thanks in advance
