Hi dear Everybody !

I hope all are fine.
Hopefully, somebody can you help me.
My C368 has a C-9401 code. I prit out the management list. The machine had earlier sometimes this code and C-9402 too. But since friday the code 9401 is permanently.
I changed the LED Exposure Unit with Flatban Cable, Scanner Drive Board, CCD Unit with cable without succex. I tried to upgrade the firmware, nothing.
Does have anybody idea?

Yes, it is.
It is moving in the right home position and in the shading position and light.

Hi everybody!

I solve it!!
DC Power Supply has a direct cable contact for the scanner drive PWG, especially a 12V for the CCD Unit. This pin had a contact trouble on the DC Power PWB. Horrible. I have it repaired and all right after that.

Thanks the comments and see you for all.
