has been removed and then reattach it to the new main PWB.

If the main PWB was replaced with a service supplied part, perform the following.
1. Insert the USB flash device in which an upgrade pack of the latest firmware or the Main/MMI/Browser
and Dictionary Jpn (excluding Language) were copied, into the slot on the machine and turn power on.
(see page 1-6-1).
2. After the main-circuit PWB has been replaced, perform U026 to restore backed-up data.
*: Do not replace the main-circuit PWB and the HDD at the same time.
(Otherwise, the settings retained by U026 in the HDD will not become restorable.)
*: Referring to the U000 maintenance report printed previously, enter the following values.
U278 Setting the delivery date
U402 Adjusting margins of image printing
U952 Maintenance mode workflow
