Chapter 4 Loading Flash Memory
Loading Flash Memory
Flash memory is contained in SIMMs (single in-line memory modules) located
on the controller board. Printer control languages (the “emulations”) and
printer operating system software are loaded into flash memory at the factory,
but there are times when you may have to install software:
• The customer buys the PGL or VGL graphics, the Expansion-CT, or the
IPDS 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 on CD-ROM. You copy
the appropriate file from the CD-ROM to your computer’s hard disk, then you
download that file to the printer.
You can load software through the serial, parallel, or ethernet port of the
printer:
• If you load memory through the serial or parallel port of the printer, see
“Loading Through The Serial Or Parallel Port” below. Certain load
commands differ, depending on which port you use. The different
commands are explained in the note following step 22 (page 152).
• If the printer has the ethernet interface installed, see “Loading Through
the Network Interface Card (NIC)” on page 154.
Loading Through The Serial Or Parallel Port
1. Make a printout of all saved configurations. Installing new software erases
all saved configurations and you will use the printouts to restore the
printer configurations.
2. Set the printer power switch to O (Off).
3. If the printer is already connected to the serial or parallel port of an
IBM-compatible computer running the PC-DOS™ or MS-DOS operating
system, go to step 9. If not, go to step 4.
4. Unplug the AC power cord from the printer.
5. Disconnect all data input cables from the printer interfaces.
6. Connect a parallel data printer cable to the LPT1 port or a serial data
printer cable to the COM1 port of an IBM-compatible computer running
the PC-DOS or MS-DOS operating system.
NOTE: You can connect the cable to the LPT2 port if the LPT1 port is in use.
The load commands are different if you use this port, as described in
the note after step 22.
7. Connect the data cable to the appropriate I/O port of the printer.
8. Plug the printer power cord into the printer and the AC power outlet.
