Subject: Volatility statement for Phaser 5550 laser printer

The Phaser 5550 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 system of the printer.

The image may be removed by clearing a

paper jam (resulting from the disruption), cycling power or printing a new page.

No user image data is maintained in the print controller or associated RAM following the

cycling of power.

The Phaser 5550 printer contains non-volatile flash memory on the controller board.

This

memory does not retain any variable printing data, but is used to retain firmware. No user

image data is retained in this memory.

The Phaser 5550 printer equipped with a hard disk drive will retain latent images in the hard

disk only when the job retention features are enabled/utilized such as Secure Print, Proof

Print, Saved Print, etc.

A procedure for securely erasing any hard disk data is available in a separate document titled

“Internal Hard Disk File Security”.

The Phaser 5550 printer contains non-volatile memory in the form of a configuration card.

This card does not retain any image data, but does retain printer configuration details.

This

configuration card can be removed and/or destroyed to eliminate the stored data. However,

the printer will not function properly without a replaced configuration card.

The Phaser 5550 printer contains non-volatile memory in the form of an optional font

DIMM.

This DINN does not retain any image data, but does retain user developed macros

used for overlays such as forms, logos and custom fonts and etc.

The optional font DIMM

can be removed and/or destroyed to eliminate the stored macros. The printer is fully

functional if the optional font DIMM in not installed or is removed.

The table on the next page lists the corresponding memory types for the Xerox Phaser 5550

printers. Please note there are no remnants of customer image data retained in the printer

when both the (i) hard disk drive is removed (from printers with hard drives) and (ii) the

power is cycled.
