This test sequentially applies power to each of the heaters to verify the relationship between
power applied and heating/cooling and to check the current drawn by each heater. Test results
are derived for each heater. When information about a specific heater is requested, all of the
heaters are tested as a group, and then the data for the specified heater is reported.
R# Definition
Typical
Value Actions
0 Initial Temperature
(deg c)
MFG
Only
Reports the temperature prior to application of
heater power.
This value may indicate how to interpret the
following values as the temperature "bump"
may be a different shape depending on initial
temperature. In particular the printhead only
reports a constant (room temperature), value if
the temp is < 32
o
C.
1 Average AC Current
(amps)
MFG
Only
Reports the difference from baseline AC
current during the specified heating
interval.For heaters with multiple elements in
parallel, a significantly different value can
indicate a partial failure. The nominal values
could change with operating hours.
2 Average Voltage
Change (volts)
MFG
Only
Reports the difference from baseline AC volts
during the specified heating period. Normally
the changes should be small. Negative
changes for high current heaters indicate the
load provided by the system is pulling down the
external AC supply, indicating a more robust
supply may be required.
3 Response Time
(ms)
MFG
Only
Reports the time after power is applied to the
specified heater that the temperature begins to
rise. For printhead temperatures < 32
o
C, this
time becomes the time at which the
temperature reaches 32
o
C. This is the
propagation time of the heat pulse through the
mechanism from the heating element to the
corresponding thermistor.
4 End Heating
Temperature (deg c)
MFG
Only
Reports the temperature at the end of the
specified heating interval. This may not be the
actual temperature for printhead temperatures
< 32 deg (normally the temp would be >
32 deg). For the linear portion of the heating
curve (i.e. quite a ways from the setpoint), the
end temp minus the initial temp is the
parameter of interest.
