6.3.1 TM-L90

Life	When printing labels (face	1,000,000 labels issued
	stock) with the ENTLA	(When the length of the label in the paper feeding direction is 25.4
	series (in monochrome	mm {1"} through 63.5 mm {2.5"}. The value above corresponds to
	mode)	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 label-
		issuing life is 70 km {43.5 miles} of running length.)
	When issuing receipts	10,000,000 lines printed (3.75 mm {0.15"} for one line)

		{37.28 miles} of running length.)
	When printing receipts	20,000,000 lines printed (3.75 mm {0.15"} for one line)

	monochrome mode)	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.)
	When printing labels (face	500,000 labels issued
	stock) with the ENTLB series	(When the length of the label in the paper feed direction is 25.4 mm
	(in two-color mode)	{1"} through 63.5 mm {2.5"}. The value above corresponds to
		approximately 15 km to 35 km {9.32 to 21.75 miles} of running
		length.)

	Thermal head	150 million pulses
	Autocutter	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.
MTBF		360,000 hours
		(when printing receipts with the ENTPD series in monochrome)
		(Failure is defined as a random failure occurring during the random
		failure period.)
MCBF		70,000,000 lines printed
		(when printing receipts with the ENTPD series in monochrome.
		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.)
