2.7 Reliability Specifications
(1) Life: Mechanical Unit: 20 Million Lines
Head: 100 Million Pulses, 100 Km (Head average resistance value change rate: Max.
±15%)
Auto-cutter: 65 µm ≤
Paper Thickness 100 µm: Partial Cut:
1 Million Cuts/Full Cut: 800,000 Cuts
100 µm < Paper Thickness ≤
150 µm;
Partial Cut and Full Cut are both 300,000 Cuts
* 65 µm ≤
Paper Thickness ≤ 85 µm (When paper width is 57.5 ±0.5 mm)
Partial Cut: 600,000 Cuts/Full Cut: 500,000 Cuts
* Mechanical parts life is defined as the period at which failures from wear out is entered.
<Conditions>
• Average Print Rate: 12.5%
• Recommended Thermal Paper 65µm ≤
Paper Thickness ≤ 75µm
• Print Density Standard Settings
(2) MCBF: 60 Million Lines
MCBF is defined as overall failures including accidental failures and failures from part wear out
leading to the life of the mechanical parts which is 20 million lines.
* Mechanical life is 20 million lines. The 60 million lines of MCBF relate to its durability life.
<Note>
1) Recommended Thermal Paper:
Mechanical Life is 10 million lines; MCBF is 25 million lines for 75 µm < Paper Thickness ≤
150
µm
2) The above provides the numerical values for reliability specifications when all use the
recommended thermal paper. Reliability cannot be guaranteed if different paper is used.
