Downloading Software To Flash Memory

Loading Flash Memory
Printer emulation and operating system software are loaded into flash
memory at the factory, but you will install software in some situations:
• You buy the PGL/VGL, or Expansion-C/T option after the printer is
installed
• You need to upgrade printer software
• You have replaced the printer Controller PCBA
• You have replaced the flash memory SIMM
Emulation and operating system software are stored as a compressed file on
3.5 inch floppy diskettes. These files are “executable”—you will expand them
and copy them into printer flash memory.
Flash memory is contained in two ICs soldered on to the Controller PCBA,
and an 80-pin 2MB SIMM at location U38, providing a total of 4MB of flash
memory for the printer.
Downloading Software To Flash Memory
IMPORTANT When downloading emulation and operating system software to the
printer, all other optional font files, customer-supplied logos, setup files,
and TIFF files will be erased. You will then need to reload those files.
Before starting a download procedure, be sure that you have all the
necessary files on hand.
You can download emulation and operating system software through the
Ethernet, serial, or parallel port of the printer.
1. If the printer has an Ethernet interface card, refer to your PrintNet User’s
Manual for download instructions. You are finished with this procedure.
2. Make a printout of all saved configurations. (Installing new software
erases all saved configurations. You will use the printouts to restore
printer configuration.)
3. Set the printer power switch to O (off).
4. If the printer is already connected to the serial or parallel port of a
computer capable of running an MS-DOS based PKZIP
®
self-extracting
file, go to step 11. If not, go to step 5.
5. Unplug the AC power cord from the printer.
6. Disconnect all data input cables from the printer interface.
