You can find the manual link here: http://www.office.xerox.com/userdoc/P6250/6250_Web/pdfs/reference_guide.pdf
On page 97 of the manual it states:
Using Printer Management FeaturesJob Accounting
The printer stores information about print jobs in a log file. The log file is stored either in the
printer’s memory or on an optional hard disk if one is installed in the printer. If the log file is
stored in the printer’s memory, it is lost when the printer is reset. It is recommended that a hard
disk be used for job accounting.
The log file lists job records. Each record contains fields such as user name, job name, pages
printed, job times, and toner and ink used. Not all fields are supported by all printers. For
information go to CentreWare IS online help or CentreWare Web online help.
The job accounting values reported vary depending on the protocol and print command used
when each job was printed. For example, using NPRINT over NetWare provides the printer
with the most information about the job being printed. When using Windows and NetWare, the
job name is often LST: or LST:BANNER. Other jobs from other ports may provide less
information about the job.
Job accounting is available through CentreWare IS and CentreWare Web.
