Chapter 4 Loading Flash Memory from One Diskette
Loading Flash Memory from One Diskette
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 VGL graphics, Expansion-CT, or 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 as a compressed file on
a 3.5 inch floppy diskette. This file is “executable.” You will expand it and copy
it into printer flash memory.
You can load software through either the serial or parallel port of the printer.
The load commands are different, depending on the printer port you use.
These differences are explained in the note following step 18.
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. If the printer
has an internal Ethernet interface card, do the following:
a. Cabinet models: remove the paper path (page 177).
Pedestal models: remove the top cover assembly (page 161).
b. Unplug the Centronics I/O cable from the Ethernet interface card.
c. Secure the loose end of the Centronics I/O cable to prevent the
connector from contacting any other exposed components.
d. Attach the parallel cable connector from the computer to the
Centronics I/O connector.
6. Connect a parallel data cable to the LPT1 port or a serial data cable to the
COM1 port of an IBM-compatible computer that is using the PC-DOS™ or
MS-DOS operating system.
NOTE: You can connect the cable to the LPT2 port if the LPT1 port is already
in use. The load commands are different if you use this port, as
described in the note after step 18.
7. Connect the data cable to the appropriate I/O port of the printer.
8. Plug the AC power cord into the printer.
