(Y/N)
Function or Use
Process to Clear:
DDR3 SDRAM non ECC –
System Memory
2GB N Executable code, Printer control
data, temporary storage of job
data
Power Off System
DDR2 SDRAM non ECC –
Image Memory
1GB N Image data - copy/scan/print/Fax Power Off System
DDR2 SDRAM non ECC – Page
Buffer
512MB N Scan image page buffer Power Off System
SRAM 1MB N JPEG image processing buffer Power Off System
Additional Information:
There are two main blocks of Volatile memory in the controller, System and Image memory. System memory contains a
mixture of executable code, control data and job data. Job data exists in System memory while the job is being processed.
Once the job is complete the memory is reused for the next job. Likewise Image memory holds job data in a proprietary
format while the job is being processed. Once the job is complete the image memory is reused for subsequent jobs.
Non-Volatile Memory Description
Type (Flash, EEPROM,
etc)
