Summary
Read first
The integrated circuits of board are easily damaged by static electricity. Be sure to make the following
precautions before you change any setting:
Before installing the controller board, please put it in an anti-static mat or anti-static bag.
When handling the controller board, avoid touching any metal leads or connectors
It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic components
such as a controller board. If you do not have an ESD wrist strap, keep your hands dry and first touch
a metal object to eliminate static electricity.
Prior to installation, make sure the chassis is suitable for the controller board.
Prior to installation, do not remove or break controller board S/N (Serial Number) sticker or warranty
sticker provided by your dealer. These stickers are required for warranty validation
Always remove the AC power by unplugging the power cord from the power outlet before installing
or removing the controller board or other hardware components.
When connecting hardware components to the internal connectors on the controller board, make
sure they are connected tightly and securely
To prevent damage to the controller board, do not allow screws to come in contact with the controller
board circuit or its components
Make sure there are no leftover screws or metal components placed on the controller board or within
the printer casing.
Turning on the power during the installation process can lead to damage to system components as
well as physical harm to the user
If you use an adapter, extension power cable, or power strip, ensure to consult with its installation
and/or grounding instructions
