(1)  Life 

Mechanical:  20 million lines

Auto Cutter:  2 million cuttings

 <Conditions>

 

Paper roll: 

P220AG (Mitsubishi Paper Mills Limited)

 

Paper thickness: 

65 µm

12.5%

The life of the print head and the auto cutter are strongly influenced 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 

Specifications Manual

(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 

20 million lines.

As the mechanical remains at 20 million lines, the MCBF of 37 million lines does not 

indicate its useful life.

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.
