10-6. Reliability Specifications
1) Life
Mechanical: 20 million lines
Head:
100 million pulses, 100 km (±15% max. average head resistance
fluctuation)
For 2-color printing, 50 million pulses, 50 km (±15% max. aver-
age head resistance fluctuation)
Auto cutter: 1 million cuttings (provided the paper thickness is between 65
and 85 µm)
<Conditions>
Average printing ratio:
12.5%
Recommended thermal paper: 65 µm
2) MCBF: 60 million lines
The Mean Cycle Between Failure (MCBF) is defined to be the overall failure cycle, which
includes random or wear failures that occur until the printer reaches its mechanical life of
20 million lines.
* As the mechanical remains at 20 million lines, the MCBF of 60 million lines does not
indicate its useful life.
3) Auto Cutter (Life)
1 million cuttings (provided the paper thickness is between 65 and 85
µ
m)
* All the reliability values indicated above are based on the use of the recommended thermal
paper. No reliability can be guaranteed for the use of non-recommended thermal paper.
