Problème de calibration

Hi!

I require your help regarding a problem I’m encountering.

Some of the robots I use in my classroom can’t be calibrated.
Lumisity and contraste are on 100% but robots don’t ligth white and also don’t charge programs.
I test them on white paper and black line, I have the same problem.
How can I do ?
