Certificate of Volatility

Introduction

This document is a statement regarding the volatility of customer data stored in memory devices and hard

disk drives of the HP DesignJet Z5600 Photo Printer series

The printer uses volatile memory to store customer data during the printing process. When the printer is

turned off, this volatile memory is erased.

The printer uses non-volatile memory to store device configuration information. This non-volatile information

is used to initialize the volatile memory when the printer is turned on and at the beginning of a print job.

The printer also contains a hard disk drive that retains data after the printer is powered off.

Volatile memory

Volatile memory in HP DesignJet Z5600 Photo Printer series include:

• Main RAM memory. 640 MB by default. Used as system memory. All information is erased when

the printer is powered off.

• Other volatile memory used as the main memory for some ASICs or as microprocessor cache.

Non-volatile memory

Non-volatile memory components in HP DesignJet Z5600 Photo Printer series include:

• CMOS Memory – BIOS. 4 MB. Does not contain user data. Its purpose is to act as the BIOS

bootloader.

• NVM at line sensor. 2 KB. Contains calibration tables for the sensor.

• NVM at analog encoder PCA. 256 KB. Contains printer settings and calibrations; it also contains

usage counters. It can be reset to factory defaults by a service engineer.

• NVM in I/O Card. 64 KB. Contains information with the control parameters for the Gigabit

Ethernet card.
