C Downloading Software
Loading Flash Memory
Flash memory is contained in a SIMM (single in-line memory module) located
on the controller PCBA. Printer control languages (the “emulations”) and
printer operating system software are loaded into flash memory at the factory,
but there are occasions when you may have to load this software:
• You have replaced the controller PCBA
• You have replaced flash memory
• The customer needs to upgrade printer software
• The customer needs different emulation software
• The customer buys the PGL or VGL graphics language, the
CT option, the IPDS option, or the ethernet NIC (network interface card)
option after the printer is installed
Emulation and operating system software are included as files on a CD-ROM
that comes with the printer. You will copy the appropriate file from the CD-
ROM to a computer’s hard disk, then download the file from the computer into
printer memory.
IMPORTANT When downloading emulation and operating system software to the
printer, all other optional fonts, customer-supplied logos, setup files,
feature 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 load software through the serial, parallel, or ethernet port of the
printer, and you can do it three ways:
• If your computer can run Java™ programs, you can load software through
any printer port by using the Firmware Download Utility included on the
CD that comes with the printer. (See below.)
• You can use DOS commands to load software through the parallel port or
serial port. (See page 265.)
• If the printer has the ethernet NIC (network interface card) installed, you
can load software through the ethernet port. (See page 268.)
