1.

Type of memory:

Marking Engine

DRAM:

96MB (32MB on-board + 64MB optional). The executable software is loaded

and run in this memory. It is also used for temporary storage of images,

including sent and received fax images and scan-to-email images, if

optionally equipped. This non-volatile memory is battery supported but will

loose information if removed from the unit.

Flash ROM:

16MB. This flash memory contains the code necessary to boot, the

executable code (operating system, document scheduler, etc.) and the

resident fonts. A power-on self test is performed and the bootstrap OS is

loaded. This area never contains any user image or document data. All code

except for the boot loader is stored in compressed format and is expanded in

the DRAM to be executed. When the fax kit is installed, this memory is not

used.

SEEP ROM:

256Byte. This memory contains the system’s setting information and error

log data. The information is encrypted.

Fax Card

Memory Card: 64MB Compact Flash. This device overrides the Marking Engine flash

memory when present. This device contains the code necessary to boot, all

executable code (operating system, document scheduler, etc.) and all

resident fonts. A power-on self test is performed to ensure data integrity. This

device never contains any user image or document data. All operating

system and application executable control code resides here. All code

except for the boot loader is stored in compressed format and is expanded in

the DRAM to be executed.

SRAM:

256KB. This memory contains the system’s setting information, mailbox

information, speed dial information, Fax program memory, user management

information, and transmission logs are stored in it. The data gets encrypted

to be written. This memory is backed up with the battery.

Boot ROM:

1MB. This memory contains the code necessary to boot. This non-volatile

memory has no image data stored in it.

Print Controller

DRAM:

192MB (64MB on-board + 128MB optional). The executable software is

loaded and run in this memory. It is also used for temporary storage of data

files and images. This information is not backed up and is lost when the

power to the printer is removed.
