Hello Expert, Canon image runner was moved to a new location. Now error displays "attach finisher". Do you know what may be causing this error? Thank you

Hello rob,
the copier sees the finisher is attached but it does not believe the finisher is firmly docked against the copier.There is a mechanical latching system that holds the finisher firmly against the copier and has a positive latching system, This externally mounted hardware that resides on the copier not only has a physically latching mechanism **** also has a metal tab that sticks out and penetrates an area of the finisher.This small **** on the finisher has a switch inside,When the finisher is close enough and secured to the copier the metal tab on the copier penetrates the **** on the finisher and presses the switch and tells the copier the finisher is in place.The finisher is either not close enough and docked securely to the copier, or the metal tab on the copier is bent and not reaching the switch on the finisher, or the switch was damaged by the move.
