10-8. Reliability Specifications
10-8-1. Thermal Printer
(1) Life
Mechanical:
Head:
<Conditions>
Average printing ratio:
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)
Paper width of 79.5 mm:
Paper width of 75.5 or 57.5 mm:
* 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.
10-8-2. Slip Printer
(1) Life
Number of printing columns: 15 million lines
Head:
Ribbon:
Note: The life of the ribbon has been determined under the test conditions existing in our
facilities.
(2) MCBF: 37 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
15 million lines.
* As the mechanical remains at 15 million lines, the MCBF of 37 million lines does not
indicate its useful life.
