Subject: Volatility statement for Phaser 5500 series printers

Phaser 5500 series printers do 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 5500 series printers do 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 5500 series printers contain 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 5500 series printers equipped with an optional 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.

The chart below shows the corresponding memory types for the Xerox Phaser 4500 printer. Please note there are no

remnants of customer print data retained in the printer when the optional Hard Disk Drive and/or Font DIMM is

removed and (ii) the power is turned off.
