20,000,000 lines
NOTE: The line spacing for the ANK or multilingual model is 4.23
mm {0.17"}, and for the Japanese model is 3.75 mm {0.15"}.
The reliability values above are measured when a 15-line
feed and a 10-line print repeat alternately.
150 million pulses
150 km {93.21 miles} (when single-color thermal paper is used)
75 km {46.60 miles} (when two-color thermal paper is used)
NOTE: The life of the thermal head when two-color thermal paper is
used is reduced to half of the life when the single-color
thermal paper is used.
2,000,000 cuts (except for KF50)
1,200,000 cuts (for KF50 (KANZAN))
(The printer is defined to have reached the end of its life when it
reaches the beginning of the wearout period.)
360,000 hours
(Failure is defined as a random failure occurring during the random
failure period in the life period – 20,000,000 lines for single-color
printing.)
70,000,000 lines
(This is an average failure interval based on failures relating to wearout
and random failures up to the life period – 20,000,000 lines.)
