Hello all.

I would like someone help me with this issue.

I have ascreen plate rite 4000II which, while it is starting, presents this error:

e4e25 sensor for the periphery of the optical unit has not been connected

I would like to know what sensor is it, on the othe hand, if someone has suggestions, please, let me know.

Most probably broken signal cable in black tray between laser head and the rest of the imager.
