An
"FFFF"
result display indicates the memory is normal.
Any other display indicates abnormality.
Check of shading memory, and display of result
2
Two digits will be displayed. The first digit represents a count
based on the thermal head PCB unit's synchronized signal, and
the second a count based on the main PCB unit's start signal.
These counts rise from
0 up to 7
, in increments of 1.
The increments occur at intervals of approximately 1 second.
Check of thermal head and main PCB unit synchronized signals
2
The ambient temperature will be displayed as a value
between 0 and 35 (
y
y
)
.
Display of ambient temperature according to thermistor in main PCB unit
Check that the increment of both digits occurs at a rate of
approximately 1 second per implement, so that
over a
period of 10 second
, there is no marked difference between
the two values. A marked difference indicates abnormality.
2
A value
between 000 and 255
will be displayed. To obtain
the time lapse since the last print run (in hours) multiply
the value displayed by
