D95- Copy Code issues

I have 4-D95 copiers at my business and we are having issues with the accounting portion of the copier. 

When staff print from their devices (OSX), we can see on the usage that it was from their computers. However, when we set the staff up with copy codes, the codes do not register on the usage reports. We can see total usage by each copy code, but on the Job History Report, it shows as a blank owner. 

Is there a way for the machines to register who is copying what with what copy code without going into the total usage reports to figure out how much someone has copied?

Thanks!
