It looks like I am stuck until I look into a 3rd party to help me differentiate who is copying what... thanks for all your help.
On a sidenote, not logging copying usage per account is a poor design on the part of Xerox. There really isnt any reason then to create accounts for each person in a building if it isn't going to keep track per job (except going in to total usage and doing the math when needed, which would get old really fast if you have someone that made a 500 page copy and you have to go through each account).
