Firmware Errors
Resolving the Upgrade Failed error
Symptom: An Upgrade Failed error is displayed on the LCD during the upgrade process
Step Procedure
1 Determine if there is interference from an external device.
a. Do not use an A/B switch box, dongle key or other peripheral in line with
the parallel cable.
b. If using a switch box, dongle key or other peripheral, remove it while testing
communication between the computer and the Printer.
c. If needed, replace the switch box, dongle key or other peripheral (once it is
determined that the cause of the interference is not the switch box or
peripheral).
d. Alternative: Add a second parallel port into the computer (if a second
Printer is required).
2 Ensure that the proper procedure is being used.
a. Be sure to follow the instructions on the attached HDP Firmware Upgrade
Guide to insure that the correct data is being transferred to the Printer.
b. It is possible that the Firmware Update Program is corrupt. In this case, the
entire program should be uninstalled from the PC and the newest version
of the program should be downloaded and installed from Fargo’s web site:
