T2500 eMFP Series Certificate of

Volatility

Introduction

The following is a statement regarding the volatility of customer data stored in memory devices

and hard disk drives of the HP Designjet T920 and T1500 ePrinter Series and the HP Designjet

T2500 eMFP 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 T920, T1500 ePrinter and T2500 eMFP Series include:

• Main RAM memory. 1536 MBytes by default. Used as system memory. All information is

erased when the printer is powered off.

• I/O Card: 128MB used to manage printer communications. All informacion is erased

when 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 T920, T1500 ePrinter and T2500 eMFP Series

include:

• NVRAM – BIOS. 2 MBytes. It does not contain user data. Its purpose is to act as the

bootloader for the BIOS.

• CMOS Memory. 256 Bytes. It does not contain user data. Its purpose is to contain BIOS

parameters.

• • • NVM in ink supplies. 1Kbyte per ink cartridge. It contains usage information and control parameters for the ink supply. NVM in printheads. 256 bits per printhead. It contains usage information and control parameters for the printhead. NVM at line sensor. 2KB. It contains calibration tables for the sensor. • NVM at analog encoder PCA. 256 KB. It contains printer settings and calibrations; it also contains usage counters. It can be reset to factory defaults by a service engineer. NVM. 64 Kbit.

• Calibration data, printer settings, usage information and accounting information can be erased by service engineers Designjet T920, T1500 and T2500 support Secure Disk Erase and Secure File Erase according to the U.S. Department of Defense 5220-22.M specification. Secure Disk Erase and Secure File Erase allow erasing the information from the Hard Disk drive in a secure mode which makes it impossible to have this information recovered.
