10-384 Job Incomplete External Heat Roll Not Ready RAP
The External Heat Roll declared Not Ready during a job and the External Heat Roll Lamp was
On continuously for 3 minutes after the machine stopped, but the External Heat Roll did not
reach operating temperature.
Initial Actions
Refer to BSD 10.3 and 10.12 for the following procedure.
Procedure
Cheat the Front Door Interlock. Switch on the power. Enter dC330 010-029 External Heat Roll
Lamp. Press Start. ACH is measured momentarily between P/J100-1
on the SSR and P/
J15-1 on the AC Driver PWB (ACN into AC Driver PWB).
YN
Go to the OF
10-5 Ex
ternal Heat Roll AC Power RAP.
Open the drawer. Remove the cheater on the Front Door Interlock. Measure the resistance
across t
he External Heat Roll Heater Rod ( P/J193-1 to P/J196-1). The resistance is less
than 10 O
hms.
YN
Replace the External Heat Roll Heater Rod (PL 8.8).
Measure the resistance across the External Heat Roll Thermostat. The resistance is less
th
an 10 O
hms.
YN
Replace the External Heat Roll Thermostat (PL
8.8).
Check
the resistance of the harness as follows:
• Switch off the power.
• Cheat the Front Door Interlock Switch.
• Disconnect P/
J41
3A from the IOT Drive PWB.
• Check the resistance between J413- A13 and J413-A11 of the harness. The resistance
should be in the range of 0.
78K ohms when the Heat Roll is hot, to 150K ohms when cool
(room temperature).
The resistance is within specification.
YN
Disconnect P/J175 on the External Heat Roll Control Thermistor. The resistance should
be i
n t
he range of 0.78K ohms when the Roll is hot, to 150K ohms when cool (room tem-
perature). The resistance is within specification.
YN
Replace the External Heat Roll Control Thermistor (PL 8.8).
Go to Fl
ag 6 and Fla
g 4 of BSD 10.3. Check for an open circuit or short circuit to ground.
Check the following:
• Check the External Heat Control Thermistor for cleanliness, damage and excessive wear
at t
he point where the Thermistor contacts the Heat Roll. Ensure that it is installed cor-
rectly.
• If the surface of the Thermistor is worn, replace
the
External Heat Roll Control Thermistor
(PL 8.8).
• Inspect the surface of the Heat Roll for excessive wear due to the Thermistor.
• Replace the Pressure Roll if necessary (PL 8.8).
If the problem continues, replace the E
xternal Heat Roll Control Thermistor (PL 8.8).
If the fault persists, replace the IOT Drive PWB (PL 9.2).
