I suppose technically you are correct that the fuser lamp pulses on and off at 60hz. But the same is true for the ordinary light bulb. The only problem is that it does it so fast that the human eye can't see it. As far as when a fuser lamp (or light bulb) draws the most power during the AC sine wave? Well, I agree it's never zero and to explain any further would require going into RMS power measurements.
