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 f ailures r elating to wearout
and random failures up to the life of 15 million lines.)

NOTE: If the printer is not used for a long time with paper installed, some part of the printing may be
light due to the deformation of the paper. If the printer is not used f or a long time with paper
installed, be sure to feed paper approximately 30 mm {1.18"} before printing.
