Appendix D Loading Flash Memory from Multiple Diskettes Loading Flash Memory from Multiple Diskettes Flash memory is contained in SIMMs (single in-line memory modules) located on the controller board. Printer emulation and operating system software are loaded into flash memory at the factory, but you will install software in some situations: • The customer buys the PGL or Code V graphics option after the printer is installed • The customer needs to upgrade printer software • The customer needs different emulation software • You have replaced the controller board • You have added or replaced the flash memory SIMM Emulation and operating system software are stored as compressed files on more than one 3.5 inch floppy diskette. You will recombine the multiple files from the diskettes into one file on your computer's hard disk in order to download the file to the printer. To assist in this process, the MS-DOS® based program PKUNZIP® is included on the last diskette with the program file. You can load software through the serial, parallel, or Ethernet ports of the printer. Note The following procedure is for loading software through the serial or parallel port. To download software through the Ethernet interface, refer to the LineJet Print Server User's Guide, 170989-001PX. The load commands are different, depending on the printer port you use. These differences are explained in the note following step 26. 1. Make a printout of all saved configurations. (Refer to the User's Manual.) (Installing new software erases all saved configurations. You will use the printouts to restore printer configuration.) 2. Set the printer power switch to O (off). 3. 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 10. If not, go to step 4. 4. Unplug the AC power cord from the printer. 5. Disconnect all data input cables from the printer interface. 288

Appendix D
Loading Flash Memory from Multiple Diskettes
Loading Flash Memory from Multiple Diskettes
Flash memory is contained in SIMMs (single in-line memory modules) located
on the controller board. Printer emulation and operating system software are
loaded into flash memory at the factory, but you will install software in some
situations:
The customer buys the PGL or Code V graphics option after the printer is
installed
The customer needs to upgrade printer software
The customer needs different emulation software
You have replaced the controller board
You have added or replaced the flash memory SIMM
Emulation and operating system software are stored as compressed files on
more than one 3.5 inch floppy diskette. You will recombine the multiple files
from the diskettes into one file on your computer’s hard disk in order to
download the file to the printer. To assist in this process, the MS-DOS®
based program PKUNZIP® is included on the last diskette with the program
file.
You can load software through the serial, parallel, or Ethernet ports of the
printer.
The load commands are different, depending on the printer port you use.
These differences are explained in the note following step 26.
1.
Make a printout of
all
saved configurations. (Refer to the
User’s Manual
.)
(Installing new software erases all saved configurations. You will use the
printouts to restore printer configuration.)
2.
Set the printer power switch to O (off).
3.
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 10. If not, go to step 4.
4.
Unplug the AC power cord from the printer.
5.
Disconnect all data input cables from the printer interface.
The following procedure is for loading software through the serial or
parallel port. To download software through the Ethernet interface, refer to
the
LineJet Print Server User’s Guide
, 170989-001PX.
