A new main board revision has been made for the VJ-626UF with part number DH-40237. The main board has been revised so it offers a stronger torque margin for the Z-motor (stepper motor of the lifting-table).
This implies some changes in the main board spare part numbering which should be used for the correct model of printer:
Old situation:
| DG-48128 - Main board assy | |
| Usable on | VJ-426UF & VJ-628UF |
 |
New situation:
The correct main board numbers can be identified and used as a spare in the following configurations:
| DG-48128 - Main board assy | DH-40237 - Main board assy | |
| Usable on | VJ-426UF | VJ-626UF |
 |
|
|
| Note | Serial header is FTP****** | Serial header is FUD****** |
| Note: When replacing the mainboard in the VJ-626UF we strongly recommend to use DH-40237 spare part only. |
All new VJ-626UF units with serial number IQ2U000392 or higher, will standard be equipped with the new main board revision. Spare part lists will be adapted according in future releases.
