HP Designjet T2500 eMFP Series - Certificate of Volatility

This statement provides a generic view of memory device volatility for the stated HP Designjet printers. It should not be used

as a supporting document either directly or indirectly for any claims against Hewlett-Packard. HP assumes no obligation to

any legal issues arising from the use of this document either directly or indirectly. This document is privileged, confidential,

and contains private information. Any reading, retention, distribution, or copying of this communication by any person other

than its intended recipient is prohibited.

Introduction

This document is a statement regarding the volatility of customer data stored in HP Designjet T2500

eMFP Series memory devices and hard disk drives.

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

is turned off, the 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 the HP Designjet T2500 eMFP Series includes:

 Main RAM memory. 1.5 GB 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 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 the scanner module. Used by this module for scan job

processing.

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

processing.

Non volatile memory

Non volatile memory components in the HP Designjet T2500 eMFP Series include:

 NVRAM – BIOS. 2 MB. Does not contain user data. Its purpose is to act as the BIOS bootloader.

 CMOS Memory. 256 Bytes. Does not contain user data. Its purpose is to contain BIOS parameters.  NVM in ink supplies. 1KB per ink cartridge. Contains usage information and control parameters for the ink supply.  NVM in printheads. 256 bits per printhead. Contains usage information and control parameters for the printhead.  NVM at line sensor. 2KB. Contains calibration tables for the sensor.  NVM at analog encoder PCA. 256 KB.

There are different options to erase part of the user information on the hard drive:  User plots in native format stored in the Job Storage folder of the printer can be erased manually by users with administrative access to the printer’s Embedded Web Server.  User plots in rasterized format (in the printer’s queue) can be erased from the queue by users with administrative access to the printer’s Embedded Web Server or with access to the printers front panel.
