Maintenance
Reference
11. Turn off the power of the machine, and then turn it back on.
12. Print a configuration or maintenance page to check the machine's firmware version.
Do not turn off the machine until the update completion message appears on the
machine’s control panel. Otherwise, the controller board will be damaged.
If the update completion message does not appear, the download failed. Try again. You
can also switch from an Ethernet connection to a USB connection and see if that works. If
you still cannot download the firmware, it may be necessary to change the EGB and/or
the controller board.
If power failed during the download, try again. If you still cannot download the firmware, it
may be necessary to change the EGB and/or the controller board.
