1.6.3 Reliability
1.6.3.1 Slip/Validation printer section:
1.6.3.2 Endorsement print mechanism section:
Life: Mechanism: 15,000,000 lines
The printer is each defined to have reached the end of its life
when it reaches the beginning of the Wearout Period.
MTBF: 180,000 hours
Failure is defined as a Random Failure occurring during the
Random Failure Period.
MCBF: 37,000,000 lines
This is an average failure interval based on failures relating to
Wearout and Random Failures up to the life of 15 million
lines.
Print head life: 200 million characters (when printed with Font B only)
Note
Printing pattern: Average 2 dots / wire per character
This printer has nine wire (dots) vertically and prints characters
moving horizontally. If one wire prints repeatedly, the problem may
occur. Consider this when you use the printer.
Example:
If the characters which consists of the horizontally adjacent dots
such as "H", "L", "-", or " A" are repeatedly printed, the number of
the printed lines should be ten or less. If more than ten such lines
need to be printed, the printer should pause for a time longer the
total printing time for each 10 lines.
MICR reader mechanism
(only when the printer is
used with the MICR reader):
240,000 passes (when used with US personal checks)
Life: Mechanism: 1,350,000 lines
The printer is defined to have reached the end of its life when
it reaches the beginning of the Wearout Period.
MTBF: 180,000 hours
Failure is defined as a Random Failure occurring at the time
of the Random Failure Period.
MCBF: 3,300,000 lines
This is an average failure interval based on failures relating to
Wearout and Random Failures up to the life of 1.35 million
lines.
