Subject: Volatility statement for Phaser 7400 color printers
Phaser 7400 printer does not retain any latent user image in the mechanical system of the printer during normal
operation. If a print job is disrupted prior to completion a latent image may exist in the mechanical systems of
the printer; the image may be removed by cycling power or printing a page.
Phaser 7400 printer does not retain any latent image in the print controller (raster image processor) or associated
RAM following the completion of printing. No user data is maintained in the print controller or associated
RAM following the cycling of power.
Phaser 7400 printer contaisn non-volatile flash memory contained on the controller. This memory does not
retain any variable printing data, but can be used to retain software updates, store fonts, etc.. No user
information is retained in this memory.
Phaser 7400 printers equipped with hard disk drives will retain latent images in the hard disk only when the job
retention features are enabled / utilized (Secure print, proof print, or saved print or job accounting).
A procedure for securely erasing any hard disk data is an appendix to this document.
Phaser 7400 printers contain non-volatile memory in the form of a configuration card. This card does not retain
any variable printing data, but does retain printer configuration details, including network address, configuration
details, printer name, etc. This configuration card can be removed and/or destroyed to eliminate the stored data.

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. - Page 4 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.
- Page 5 Xerox Phaser printers support a “Printer Neighborhood” feature in the printer’s CentreWare IS internal web server. This feature performs a network discovery to find other Xerox Phaser printers on the network, and can optionally discover non- Xerox printers as well. To increase the performance of this feature, the printer stores the list of discovered network printers in a cache file on the internal hard disk, if it is present.
- Page 6 To address these security concerns, Xerox Phaser printers now support a Hard Drive Overwrite Security software feature. This feature obliterates the data stored on the hard disk of a file marked for deletion, before the file’s directory entry is removed...
- Page 7 The printer’s administrator can configure the printer to automatically delete unprinted Secure, and Proof print jobs after a specific amount of time has elapsed since the job was sent to the printer; or after at certain time of day, or immediately upon pressing a button.
- Page 8 5. Setting Printer Security Features The printing security settings of the printer, including security settings affecting files on the printer’s internal hard disk, can be configured from within the printer’s CentreWare IS internal web server, from the “Security” selection available in “Properties”...
