Do not turn on machine power with the triac leads disconnected. This
will burn out the opto-isolater on the AJ1 PC board. Do not switch the
(m) Temperature sensor testing requires that you disconnect the leads
of the probe from the rest of the circuit and check for resistance between the leads. The
developer sensor is connected to terminal strip TS5, at TS5-2 and TS5-3. You check
the dryer sensor at TS3-2 and TS3-1. The resistance of the sensor varies with
temperature. Figure 1-25 gives the resistance of the sensor according to temperature.
Both developer and dryer sensors are the same. If in doubt, check at room
