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.
