10-382 Stand By External Heat Roll Not Ready RAP
The External Heat Roll Lamp was On continuously for 1 minute during the Standby Mode, 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).
Swit
ch off the power. Cheat the Front Door Interlock Switch. Disconnect P/J413A f
rom the IOT
Drive PWB. Check the resistance between J413-A13 and J413-A11 of the harness. The resis-
tance 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 F
lag 4 of BSD 10.3. Check for an intermittent 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
Pres
sure Roll if necessary (PL 8.8).
If the problem continues, replace the External Heat Roll Control Thermistor (PL 8.8). I
f the fault
persists, replace the IOT Drive PWB (PL 9.2).

The External Heat Roll Lamp was On continuously for 3 minutes after the current job com-
pleted, but the External Heat Roll did not reach operating
temperature.

External Heat Roll AC Power RAP.
Open the drawer. Remove the cheater on the Front Door In
terlock. Measure the resistance
across the External Heat Roll Heater Rod ( P/J193-1 to P/J196-1). The resistance is less
than 10
Ohms.
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
