Loading optional
firmware
If you download new firmware as described below, all menu
settings will be overwritten. For this reason you should print a
menu dump in orto be able to reestablish the previous settings
if necessary (see Printing out menu configurations (Print),
page 47).
To load new firmware, proceed as follows.
The most current version of the firmware can be downloaded
from our internet page.
1Switch off the printer. Connect your DOS PC (LPT1:) to the par-
allel port on the printer.
2Press keys 1, 4 and Online. Hold the keys pressed.
3Switch on your printer.
The printer is ready for the download when BOOT appears on its
display.
4In Windows open the MS-DOS window.
5Copy the file, e.g. DOWNLOAD.FDF, to your printer:
COPY /B X:\path\DOWNLOAD.FDF PRN
(X:\path stands for the drive and the directory in which the file is lo-
cated.)
A progress indicator (bar) and DOWNLOAD FIRMWARE appears
on the display during the download; alternatively, an error message
is displayed:
PRG = Firmware
GEN = Character set or font (character generator)
P+G = Firmware and character set
BOO = Firmware, character set and boot block
The number of the currently transferred data block (frame) is dis-
played in addition in the top line of the display on the right.
DOWNLOAD OK and BOOTAREA SKIPPED is displayed briefly
when the procedure has been completed successfully. The printer
then runs through its initialisation routine, after which it is ready for
use. Repeated separate loading of firmware and character genera-
tors is possible.
Troubleshooting It is necessary to repeat the entire procedure if an error occurs dur-
ing the download. This is indicated by a corresponding message on
the display. It may be that not all fault messages can be shown on
the display. In this case, the operating system of your PC displays
an error message such as “Write error on device”.
