1.11 Reliability

1) Life:
Mechanism:	15,000,000 lines
Thermal head:	100 million pulses, 100 km
Auto cutter:	1,500,000 cuts
	(End of life is defined to have reached the end of its life when it reaches
	the beginning of the Wearout Period.)
2) MTBF:	360,000 hours
	(Failure is defined as Random Failure occurring at the time of the
	Random Failure Period.)
3) MCBF:	52,000,000 lines
	(This is an average failure interval based on failures relating to wearout
	and random failures up to the life of 15 million lines.)
