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 the following section, “Downloading System Software to a Non-Functional Printer.”

If the print system software is functional (the printer starts up nor- mally, and IDLE displays in the message window), and if you decompressed 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 “Cable Pinouts” section of appendix B, “Technical Specifications,” if you want to make your own cable.

1Connect 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.

2Turn 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.
