(2) Downloading the firmware from the parallel interface
This section explains how to download firmware data from the parallel interface. The printer system can automatically
recognize whether the data to be overwritten is for controller firmware.
CAUTION
Downloading the firmware takes several
minutes. Do not turn power off during
downloading.
NOTE
MS-DOS is required for a downloading from
the parallel interface. The computer must be
connected to the printer with a parallel
cable.
Procedure
1. Turn printer power on. Make sure the printer is
ready.
2. At the DOS prompt, send the following
command to the printer:
echo !R! UPGR "SYS";EXIT;>prn
3. Confirm that downloading was finished
normally by the LED indicator. (See page 1-
7-4)
4. Turn power off.
5. Turn power on again. Check the printer gets
ready.
* Confirm the status page shows the new
firmware version (See service information
on the status page). If downloading fails, the
printer indicates an error display using the
LED indicators. To identify error, refer to the
table on page 1-7-4.
