1. Supported Printers

Xerox Phaser printer models now incorporate security features for data stored on the

printer's internal hard disk. Refer to the printer's documentation or visit

http://www.xerox.com/officeprinting

printer supports internal hard disk security options.

Earlier models of Xerox Phaser printers cannot be upgraded to support internal hard

disk security.

2. Types of data stored on the printer's internal hard disk

An internal hard disk is an optional feature for some models of Xerox Phaser printers.

Not all printer models can support an internal hard disk.

The internal hard disk on a Phaser printer is used in several ways to improve printing

performance, to implement additional features, and to improve printer usability and

management. Security-conscious users often wish to know what types of data are

stored on the internal hard disk.

When present, the printer uses the internal hard disk for the following purposes and

data types:

a. The printer stores page content data for Saved, Secure, Proof, and printer-

collated print jobs. Print jobs sent for immediate printing, e.g. Normal jobs that

do not use printer-based collation do not have their page content data saved on the

printer's internal hard disk.

For Saved, Secure, Proof, and printer-collated print jobs, the printer must be able

to access each page in a print job out of the order they were transmitted to the

printer, and possibly at a later time. Because the contents of only a few pages at a

time can be stored in RAM memory, the page content data is stored on the

printer's internal hard disk. These types of print jobs are not available without an

internal hard disk.

Page content data files are stored in a Xerox proprietary, unpublished compressed

binary data format. These data files are not directly accessible from any printer

interface other than the standard controls or commands for printing jobs, e.g. no

feature exists for transferring or retrieving this data to another computer or

printer.

For Proof, Secure, and printer-collated print jobs, the page content data files are

deleted by the printer when the print job is completed. The page content data files

for Saved print jobs are stored on the printer's internal hard disk and accessed

through the printer's CentreWare IS internal web server or the printer's front

panel, until they are explicitly deleted by the user.
