Makerbot 5th Gen Smart Extruder Error

[Wacker357]

I am having a problem with smart extruder on a printer. I have a printer of model MB 5TH generation 3D.
when I attach a extruder, the printer make an error about extruder attachment. I tried with different type of extruder, but the problem is the same.
I check connector pins, but they are OK. What should I do now…???
