Turn off the main power switch of the MFP and disconnect the power cord.
After replacing, make sure that all disconnected harnesses are connected up again and secured in their clamps (if the MFP has harnesses).
When handling the operation panel cable, hold down the connector of the cable with your finger as shown in the picture to prevent excessive force from being applied to the connector of the PCB.
If excessive force is applied to the connector of the PCB in the direction of the arrow, connection failure may occur.
For machines manufactured in October 2016 or later, a bracket [A] will be added to cover the connector of the cable.

By factory default, switches No.3 and No.7 of the DIP switch [A] on the micro computer board are set to ON. When installing the operation panel unit, make sure that the DIP switch setting is correct for the MFP on which you are installing the panel.
The correct DIP switch setting depends on the MFP. Note the DIP switch settings of the old operation panel unit before replacing, and apply the same settings to the new Smart Operation Panel. (Below are two examples for DIP switch settings.)
