1.1 The color parameter is kept in 24LC256( locate at U619),
and the color parameter is different due to different optical engine.
1.2 EDI will provide a new 24LC256 with a new optical engine when you need to change an
optical engine. The color parameter settings of the 24LC256 have to match with the optical
engine in EDI factory.
1.3 When you replace an optical engine or main board, please always confirm the 24LC256 go
with its original optical engine.
2.1 Make sure the direction of 24LC256 on main board, the mark (*) at the left side.

automatically.

original optical engine when you replace the main board or Optical Engine.
