Upgrading Printer Firmware
About this Chapter
This chapter provides information about maintaining your printer. Although the printer requires
very little maintenance, with normal daily use you will need to perform some routine maintenance
procedures, including replacing consumable items and cleaning the printer.This chapter also con-
tains information about moving and storing the printer.
Upgrading Printer Firmware
The executable firmware for the printer controller is stored in FLASH memory. You can easily
upgrade this firmware on site when a new version of code is available. The upgrade process involves
sending the new code, which is usually named with a .LOD extension, to the printer using either
the parallelor network interface. When the printerreceives the file, it will automaticallyrecognize it
as a firmware upgrade file and will program it into the FL ASH memory.Dur ing this process the
printer will display information about each sub -file that it is receiving or programming. When fin-
ished, the printer displaysthe text “Upgrade Completed” and reboots, executing the new firmware.
Contact your dealeror service provider for more information about firmware upgrades.
Upgrading Firmware Using the Parallel Interface
Toupgrade the printer using the parallel interface, go to the DOS prompt and use the copy com-
mand to copy the new file to the printer. For example, type “copynewversio n.lod/b lpt1” at the
DOS prompt, where “newversion”is the name of the firmw areupgrade f ileand “lpt1” is the p rinter
you would like to upgrade.Be sure to use the “/b” switch on the copy command line to ensure that
the data is sent in binary mode.
NOTE: If you are using a PC that is not running Windows or if you do not have any printer drivers
installed and configuredto use the parallel interface, you will need to configure the parallel port
for permanent retry by entering the following commandPRIOR to entering the copy command
discussed above: mode lpt1:,,p
If you are running Windows, you may get an error message during the upgrade process that
indicates that the printer is busy or that there is a printererror. This message box will contain
check-boxes for “Retry” or “Cancel”. DO NOT SELECT CANCEL. This error message is only a
result of the printer programming a large fileinto FLASH memory and will disapp ear onceth e
programming is completed.
Upgrading Firmware Using the Network Interface
Toupgrade print er firmware using the network interface, simply send the new file to the pr inter
using whatever procedure you normally use to send a print file. This procedure varies depending on
the networkenvironment.
