# is 1 to 4. (/b refers to binary files.) If you’re not sure of the
number of the serial port, check your PC’s documentation.
The downloading process takes about 5 minutes, depending on
the size of the file and the speed of your PC. The Ready indicator
blinks as the new system image is copied to flash ROM. After the
updated system software has been written to flash ROM, the
printer reboots with the new system image, prints a start-up page,
and returns to IDLE.
» Note:
The new flash image does not erase the old image until the
printer verifies that the new image is valid.
11 Print another advanced status page, and verify that the cur-
rent configuration settings match the previous configuration
settings (on the advanced status page printed in step 5).
12 If there are differences in the configuration settings, correct
them through the printer configuration menu.
If the print system software is functional (the printer starts up nor-
mally, and IDLE displays in the message window), go to one of the
previous sections, “Downloading System Software to a Functional
Printer—SYSTEMDL.PS” or “Downloading System Software to a
Functional Printer—SYSTEM.DL.”
If the print system software is non-functional (the printer can’t start
up), use these instructions to download the system software.
If the current print system software is not functioning, you must con-
nect your Macintosh to the printer’s serial port to reinstall the system
software. The downloading procedure will not work over the LocalTalk
or CrownNet interface in this case.
