HP Designjet T1600, T2600 MFP and XL3600 MFP 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 T1600 Printer Series and the HP Designjet T2600 and

XL3600 MFP 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 T1600 Printer Series and the HP Designjet T2600 and XL3600

MFP Series include:

 XL3600 Main RAM memory. 8GBytes by default. Used as system memory. All

information is erased when the printer is powered off.

 T1600 Main RAM memory. 4GBytes by default. Used as system memory. All information

is erased when the printer is powered off.

 T2600 Main RAM memory. 8GBytes 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.

 SDRAM memory. 512 MB Located on scanner module. Used by this module for scan job

processing.

 SRAM memory. 12 MB. Located on scanner module. Used by this module for scan job

processing.

Non volatile memory

Non volatile memory components in HP Designjet T1600 Printer and T2600 and XL3600 MFP

Series include:

 XL3600 NVRAM – BIOS. 128 Mbits. It does not contain user data. Its purpose is to act as

the bootloader for the BIOS.

 T2600 NVRAM – BIOS. 16 MBytes. It does not contain user data. Its purpose is to act as

the bootloader for the BIOS.
