Firmware Errors
Resolving an 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). See the Updating the Main Firmware
procedure on page 210.
Alternative: Add a second Parallel Port into the computer (if a second Printer
is required).
