Reliability TM-L90 Life MTBF MCBF When printing labels When issuing receipts (thickness type) When printing receipts Thermal head Autocutter 1,000,000 labels issued (When the length of the label in the paper feeding direction is 25.4 mm {1"} through 63.5 mm {2.5"}. The value above corresponds to approximately 30 km to 70 km {18.64 to 43.5 miles} of running length. When printing labels whose length exceeds 63.5 mm, the labelissuing life is 70 km {43.5 miles} of running length.) DTM9502 (only for 4** models): 700,000 labels issued (1,000,000 labels issued after cleaning the platen.) 10,000,000 lines printed (3.75 mm {0.15"} for one line) (The value above is calculated based on the printer using 15-line feeding and 10-line printing repeatedly with a 145 m paper thickness. The value above corresponds to approximately 60 km {37.28 miles} of running length.) 20,000,000 lines printed (3.75 mm {0.15"} for one line) (The value above is calculated based on the printer using 15-line feeding and 10-line printing repeatedly with 75 m of paper thickness. The value above corresponds to approximately 120 km {74.57 miles} of running length.) 150 million pulses When cutting receipts: 2,000,000 cuts (except for KF50, when the paper thickness is less than 75 m) 1,200,000 cuts (for KF50 (KANZAN)) 1,000,000 cuts (when the paper thickness is more than 75 m and less than 145 m) When cutting labels: 1,000,000 cuts (Cutting between the labels) 500,000 cuts (Cutting labels not die-cut. 1,000,000-cut is available by cleaning the blade.) Note: When cutting die cut labels, cut between the labels. 360,000 hours (when printing receipts with the ENTPD series) (Failure is defined as a random failure occurring during the random failure period.) 70,000,000 lines printed (when printing receipts with the ENTPD series. This is an average failure interval based on failures relating to wear out and random failures up to the life of 20,000,000 lines printed.) 134 Appendix
