When replacing the main PWB, remove the EEPROM (YC14) and DIMM (YS1,YS3) from the main PWB that
has been removed and then reattach it to the new main PWB.
When refitting DIMM, Refit them to the original positions.

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.)

U278 Setting the delivery date
U402 Adjusting margins of image printing
