Duplex scanning on Brother MFC9340-CDW are blue

[depanninfo06]

Hello,


I have just changed the scanner lamp of the adf on my brother MFC-9340CDW, no problem on the front side in black and white but in color the back is all in blue. You can see on vuescan below
I tried to make Acquisition of White Level Data with code 55 like on SM but get an error :scan error adf in maintenance mode.
Does anyone have any idea where it could be coming from?
Thanks in advance

did you retrace all your steps to make sure all connections were seated properly?

Finally, i got the solution. I tried with another cis scanner module, go on maintenance mode and make white registration (Code 55) and all is fine.
