Subject: Volatility statement for Phaser 7750 color printers

Phaser 7750 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 7750 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 7750 printer contains 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 7750 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).

The chart below shows the corresponding memory types for the Xerox Phaser 7760 printer. Please note, there
are no remnants of customer print data retained in the printer when both the (i) hard disk drive is removed (from
printers with hard drives) and (ii) the power is turned off.
