KS55 SERIES OPERATION MANUAL
3.10 - RELIABILITY AND
ENVIROMENTAL CONDITIONS
Printer service life
15 millions lines
MCBF
37 millions lines
Print head service life
(1)
100 Km, one hundred million pulses
Autocutter service life
(1)
1 million cuts
Operating temperature
-20 to 70ºC
Reliable printing: 5 to 50
°
C
Note that there are some restrictions, depending on the
temperature range
Operating humidity
10 to 80% (non-condensing)
(Humidity at 34
°
C or higher is equivalent to the absolute
humidity at 34
°
C, 80%.)
Storage temperature
-35 to 75ºC (without paper, in a dry place)
(1)
The service life of the print head and autocutter may become shorter if paper other than specified is used.
NOTES:
1
. Reliability statistics assume that the printer repeats printing in which one dot line
consists of an average of 112 dots or less, and the average number of printing dots
per dot line per element is 30.
2
. Life end is defined as the point at which two or more adjacent heat elements are
damaged (when two or more adjacent dots are omitted), except when damaged by
foreign objects or external causes.
3
. The print head life is measured using the specified paper.
4
. Using the printer with the density correction factor of the print head energization
width set to a value larger than 1 may shorten the life of the print head
5
. The ambient temperature should be kept close to room temperature.
Stop printing when the print head temperature detected by the head thermistor reaches 75
°
C.
Resume printing when the temperature drops down to 70
°
C for lower.
