Print job page data files may pose a data security risk because they contain the
images of the pages in the print job..
b. The printer can store print job resources, such as fonts, macros, color tables, and
forms on the internal hard disk. Printing performance is improved when common
resources used across multiple print jobs are stored on the disk instead of
contained within every print job data stream that uses those resources.
These types of resources must be explicitly copied to the printer's internal hard
disk by a user by using a printer utility program, such as the Xerox Font
Management Utility. Other utility programs exist from Xerox and other vendors
for managing resources of various types on a printer's internal hard disk.
PostScript and PCL fonts may be listed and deleted from the printer's internal
hard disk through the built-in CentreWare IS web server.
Print job resource data such as fonts, and color tables are not likely to pose a data
security risk. Customer designed PostScript forms or PCL Macros may or may
not pose a data security risk depending on their contents. In any case, storing
these types of resources on the printer's internal hard disk is entirely at the user's
discretion. The printer never creates such disk files without a specific command to
do so by a utility program.
c. The printer records job accounting and usage profile information on the hard disk.
Xerox Phaser printers that support networking maintain a history of jobs printed,
with the details of each print job such as user name, job name, and the number of
pages and amount of ink or toner used. This job accounting data can be viewed
from the printer's internal web server, or downloaded to a host computer.
Small amounts of job accounting data are stored in printer RAM memory when an
internal hard disk is not present, usually the most recent 50 to 500 print jobs
depending on available RAM. Job accounting data in RAM memory are lost when
the printer is powered off or restarted.
When an internal hard disk option is present, the printer stores much more job
accounting data, usually 5000 records. This data is also preserved across printer
power off or reset cycles.
The job accounting record data is stored in a Xerox proprietary, unpublished
binary data format on the internal hard disk.
Job accounting data may be deleted from the printer through the printer's internal
CentreWare IS web server.
Job accounting record data may pose a data security risk because the names of
users, as well as the titles, date, time and lengths of printed jobs can be exposed.
The contents of print job pages are not stored in the job accounting system.
d. Additional features are available through the printer's internal CentreWare IS web
server when an internal hard disk option is present. Examples include user
manuals in PDF format, QuickTime instructional videos on printer operation and
user maintenance, and downloadable printer drivers. This content is preloaded
onto the hard disk by Xerox.
