When you replace to a board for service, the written destination data of the board for service also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “Destination data write”.

When you replace to a board for service, get the data from the former one.
Start the Adjust Manual in the Adjust Station and execute the “RESTORE DATA” to get the data. 
The data getting for this model is as follows.

• PRODUCT ID & USB SERIAL No.
• Hash data setting
• AWB standard data input & check, Color reproduction check

The unit is shipped after an ID (USB Serial No.) unique to each unit and an ID (Product ID) unique to each model have been written.
These IDs have not been written in a new board for service, and therefore they must be entered after the board replacement.
After the board has been replaced with a board for service, start the Adjust Manual in the Adjust Station and execute the “PRODUCT ID & 
USB SERIAL No. INPUT” and enter these IDs.

Note: 

A newly entered Product ID is not always equal to the ID before board replacement. If the new ID differs from the previous ID, it may cause a difference 
from the ID registered by the customer.
