[TERMINATOR 2] Why did the T-1000 threaten Sarah with force for her to "call John" instead of just copying her voice or turning into her?

He was currently making contact with her, and had done so earlier in the elevator when he cut her. Why not imitate her voice, or outright copy her entire body, and then terminate her as was standard protocol?

The T-1000 is composed of billions of tiny nanomachines that allow for its shapeshifting abilities.  These billions of tiny nanomachines had just been frozen solid by liquid nitrogen, blown apart with a 9mm round, and reformed all in the space of a few minutes.  With all of that, hardware damage is inevitable.

(Meta: deleted scenes show that, as a direct result of the above, the T-1000 was starting to malfunction hardcore)
