Be very careful when doing this, and if you must do it, only move it
very slowly. Like any motor, the stepper motor that moves the head
carriage will generate voltage when it's turned by hand. This often
fries stepper motor drivers. Slower motion generates less voltage and
is safer. I did this accidentally on my pick-and-place machine last year.
