After the update has been completed, the message "Update Successful!" is dis-
played. Turn the copier's main power switch OFF, and then turn it back ON again after
waiting for at least 10 seconds.
There is a chance that an error occurred if the updating process is not completed in about 15 min-
utes. If this happens, turn the copier's main power switch OFF, wait at least 10 seconds then turn it
back ON again, before repeating the updating process from the beginning. (Remember, however, the
time it takes for the updating process to be completed depends on computer performance.) If an error
occurred during the updating process, the firmware is not updated and the old version remains in
effect.

Caution
Avoid operating the PC and the copier as long as the message "Updating
printer controller F/W." is displayed on the copier's LCD panel.
The print controller may be damaged if you turn the copier's main power off
while this message is displayed.
Caution
If the copier's main power switch is turned ON again immediately after the
power has been turned OFF, the print controller may fail to function correctly
and errors may occur.
If this happens, turn the copier's main power switch OFF and wait at least 10
seconds before turning it back ON again.
