Certificate of Volatility

Manufacturer: Xerox

Equipment Name: Work Centre PE120/PE120i

Model : PE120, PE120i

Configuration: The PE120i is networked to print servers with operating systems Windows
98/ME/NT4.0/2000/XP/2003, MAC (web downloadable, PS print only) and Linux (scan and print
only)

General description: The PE120i printer is connected to a network.

Purpose: Multi -Functional Device, Print, Copy, Fax, and Scan

1. Type of memory:
Volatile memory: What is the amount? What period of time does the unit need to be

powered off to completely erase this memory?

User Interface Volatile memory:

DRAM: No (In FLASH ROM)
Marking Engine Volatile memory:

SRAM: No
Scanner Volatile Memory:

SRAM: 128 KB (No user image data stored.)
Copy Controller Volatile Memory:

SDRAM 28 MB (User image data stored. Data lost at power off.)
FAX Card Volatile Memory:

SDRAM 4 MB (User image data stored. Data lost at after 43hour power off )

Network Controller Volatile Memory:

SDRAM 8 MB (No user image data stored.)

Video Volatile Memory:

There are also a number of RAM buffers in the video path that are used for image manipulation
(Reduce/Enlarge, etc.), and all have no data retention capability. When power is removed all
data is lost..

Non-Volatile Memory:
Type: What type(s) of non-volatile memory are included, EPROM, EEPROM, Flash memory,

NVRAM, and battery backed, etc. (fill in)

User Interface Non-Volatile memory:

Flash ROM: No

2. Accessibility: Is it accessible by accidental/intentional keystroke, or software malfunction?

No. However, the login system administrator or service technician (via diagnostic operation)
may adjust certain machine operational parameters. User data is never accessible.

3. If "YES, it is accessible, describe location and purpose.

Purpose: typical uses for non-volatile memory location are system identification number and

system configuration, boot, and initialization parameters, for example (battery-backed NVRAM
on SUNs); put in for future design needs, internal depot repair, clock circuit, "nice" to have, or
to flag unauthorized software, etc.

If "NO", it is not accessible, ____X___ (Check here).

4. Required memory: Is device needed for normal operation, i.e. required for this processing

period?

All memory listed is required for normal operation.

5. Removal consequences: If device memory chip is erased, what impact will this have on
operation and normal function of device?
