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: NoScanner 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

Rigid Disk Drive: No
Flash ROM : 2MB (Network Control code, No user data stored)
There are other non volatile memory devices in the multi-functional device.
CRUM : EEPROM 0.5Kbyte (User data stored)
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?

Example: If the SUN is turned on without this means of checking for the authorized
configuration, the system will not boot and therefore the data cannot be processed per the
standard Practice Procedure (SPP).
ROM memory device content is required and essential for operation and normal function of the
device. Loss would render the device inoperable.
.
6. Method of access: How is it accessed? Is non-volatile memory location theoretically
accessible with any system code, not just via the operating system or low level booting
firmware?
Marking Engine non-volatile memory is used for storing Multifunction Device application
settings and is accessible by application level code. There is no user access to the memory
devices, except as provided programmatically to control device behaviors.
Remember: Modifying internal programming to access is not the same thing as unknowingly
accessing from an accidental keyboard stroke.
7. Warranty: Does chip removal or EEPROM erasure void the warranty?
Yes, memory removal or erasure will void the warranty. Disk removal of the internal disk drive
will void the warranty.
8. Size: How much memory is contained? Number of bytes, etc.
See section 1, “Type of Memory”
9. Spacing: Is the memory fully utilized or does it have available memory space for additional
information to be placed?
The non-volatile memory devices are sized to contain the necessary amount of data required for
system operation. Usually there are some unused memory addresses where additional
information could be theoretically stored. Without access to the software developers’ memory
maps, determining the location of this unused memory would require reverse engineering the
software.
10. Can this non-volatile memory be addressed to ensure that only authorized information is
resident? If yes, how?
At boot-up, the system computes a checksum for each non-volatile memory device. (Note:
The computed checksum is compared against a value stored in the device itself. This is
sufficient to detect hardware failures, but not necessarily intentional corruption.)
