136 Appendix
TM-L90 Peeler Model
The values in the above table are based on use of Epson specified paper.
Depending on the paper, paper dust and adhesive may stick to the platen, head, and peeler unit.
Life Labels Issues 1,000,000 labels
(With feed direction label length of 25.4 {1 inch} to 63.5 mm {2.5
inch}. Equivalent to a travel distance of about 30 to 70 km. When
printing labels in excess of 63.5 mm, product lifetime in number of
labels comes after a travel distance of 70 km)
Receipts 20,000,000 lines printed (with 1 line at 3.75 mm)
(Assuming repeated printing of 10 lines with paper thickness of 75
µm or less and 15 line feed. Equivalent to a travel distance of about
120 km)
Thermal head 150 million pulses
MTBF 360,000 hours
(Using receipts during the product lifetime. Failure means random
failure in the random failure period)
MCBF 70,000,000 lines printed
(Using receipts during the product lifetime. Indicates the overall
mean time between failures including wear-out failure and random
failure up to product lifetime of 20 million lines printed)
Vibration resistance When packed: Frequency: 5 to 55 Hz
Acceleration: Approximately 19.6 m/s
2
{2 G}
Sweep: 10 minutes (half cycle)
Duration: 1 hour
Directions: x, y, and z
No external or internal damage should be found after the vibration
test, and the unit should operate normally.
Impact resistance When packed: Package: Epson standard package
Height: 60 cm {23.62"}
Directions: 1 corner, 3 edges, and 6 surfaces
No external or internal damage should be found after the drop test,
and the unit should operate normally.
When unpacked:Height: 5 cm {1.97"}
Directions: Lift one edge and release it
(for all 4 edges).
When the printer is not printing, no external or internal damage
should be found after the drop test.
Acoustic noise (operating) Approximately 53 dB (ANSI bystander position)
NOTE: The value as shown above is measured when the Epson
evaluation printing pattern is used. This value may be
different, depending on the paper to be printed, the print
duty, or the print conditions, such as the print speed or the
print density.
