∗
1: Indicates the point at which the wear-out failure period starts.
∗
2: Indicates the mean time between failures during the random failure period.
∗
3: Indicates the overall mean time between failures, including wear-out and random failures, before the life is
reached.

Printer mechanism
Capable of printing 10 million lines
This is based on the assumption that the specified paper is used, that each
line is 3.75 mm, and that the paper is fed for 26 lines and 20 lines are printed
repeatedly. The total distance of paper passing through the print head is
equivalent to about 50 km.
Thermal head
50 km (when printed with recommended print density and print speed)
(Reference: 100 million dots per heating element)
MTBF
*2
120,000 hours
MCBF
*3
16 million lines
Depending on the paper condition, paper dust may adhere to the head and platen.
