Flash memory is contained in in-line memory modules (SIMMs) located
on the CMX controller board. (Shown in the
Maintenance Manual.
)
Printer emulation and operating system software are loaded into flash
memory at the factory, but you will install software in the following
situations:
•
You buy the IGP/PGL or Code V graphics option after the printer is
installed
•
You need to upgrade printer software
•
You need different emulation software
•
You have replaced the controller board
Emulation and operating system software are stored as a compressed
file on a 3.5 inch, double-density floppy diskette. The file is
“executable”. You will expand it and copy it into printer flash memory
with a single command.

configuration.
