On the Touch Screen of the printer should appear 5 functions and only appear 3 (Copy, email, fax), when they should appear in addition to the three mentioned, network scanning and Scan. Mail / mailbox
How to do or what to do with all the menus assets?

Just ONE more: To send e-mail must be connected to a print server or just connect it to the switch to communicate with fixed ip? (Since we do not have the company's own SERVERS) I think it must have print server.Model # PLEASE ?WorkCenterproC 123Model # is out of production...
JUDGING by your issues it sounds LIKE it was setup as a network printer...but you don't need it to be.
I'd suggest uninstalling it in Device Manager...then remove the software via ADD/Remove Programs...then re-booting and re-installing it fresh.We have connected to a switch. But in manual it have 5 options in menu, but we only have 3!
Does anyone knows how to put it right?
Another one: i can access to xerox web configuration but it asks login and password to change anything.

Anyone?
