9-6. Reliability Specications
(1) Life Mechanical: 20 million lines
Print Head: 150 km (150 million pulses )
Auto Cutter: 2 million cuttings
<Conditions>
Paper roll: P220AG (Mitsubishi Paper Mills Limited)
Paper thickness: 65 µm
Paper width: 115.5 mm
Cutting Mode: Partial cut
Average printing ratio: 12.5%
Note:
The life of the print head and the auto cutter are strongly inuenced by factors such as
the type of paper that you use. For information about the life of the print head and auto
cutter when they are not used under the conditions described above, refer to the separate
Specications Manual
(2) MCBF: 37 million lines
The Mean Cycle Between Failure (MCBF) is dened 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 37 million lines does not
indicate its useful life.
Note :
1) When recommended thermal paper whose thickness is above 75 µm but not more
than 150 µm is used, the mechanical life of the printer is 10 million lines and the
MCBF is 25 million lines.
2) 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.
