Kodak DryView 8300 Service Manual page 179

The running average temperature that is calculated from the RTD values begins to drop now, as more and
more low RTD readings accumulate in the running average. Once the RTD running average is filled with
648s, the average temperature value will remain constant. Note that this is NOT a valid temperature, just
as the 648 is NOT a valid representation of the true RTD value. Although 648 doesn't indicate it, the
HEATER is actually heating up because full power is being applied.

Software thinks the HEATER is too cold, because the RTD value is so low and not going higher. Software
is applying full power to the HEATER, but the RTD value is not going up. Software detects this as an
error condition and turns off the HEATER as a safety measure. Error code 19 (DEVELOPER UNDER
TEMPERATURE) is reported, because the software sees that applying power does not increase the RTD
value.
