Downloading System Software to a
Functional Printer
—
SYSTEM.DL
If the print system software is non-functional (the printer can’t start
up), go to “Downloading System Software to a Non-Functional
Printer” on page 56.
If the print system software is functional (the printer starts up nor-
mally, and
IDLE
displays in the message window), and if you decom-
pressed the file SYSTEMLOADER (Macintosh) or SYSTEM.DL (PC)
in the previous section, use these instructions.
» Note:
Before you can use these instructions, you must have
decompressed the system software, as described in the previous
section.
Macintosh
» Note: This downloading procedure requires a connection from the
Macintosh’s serial port (either the modem or the printer port) to the
printer’s serial port. The cable must have a DIN-8 female connector
on the Macintosh end. It must also must be wired as a null modem or
it must have a null modem adapter. The type of connector for the
printer’s serial port end of the cable depends on the type of null
modem assembly. Your Macintosh vendor can provide you with this
equipment, or you can use the “Pinouts” section of chapter 3,
“Technical Specifications,” if you want to make your own cable.
1 Connect the Macintosh to the printer’s serial port.
You can use either the printer or modem port on the Macintosh.
However, the modem port provides the fastest download.
» Note: To use the printer port you must first disable AppleTalk in
the Chooser.
2 Turn on the printer, wait for
IDLE
to appear in the message
window, and then print an advanced status page.
This procedure should not change the current configuration set-
tings. However, the advanced status page provides a record of all
current configuration settings, so you can verify that they are the
same after the system software has been updated.
