10-130 Duplex In Sensor On Jam RAP
The Duplex In Sensor did not actuate within the specified time after the start of Reverse Feed.
Initial Actions
Refer to BSD 10.8, 10.9, and 10.12 for the following procedure.
Check for the following:
• Obstructions in the paper path.
• Skewed sheets with LE corner damage.
• Ensure that the Upper Inverter Roll (PL
2.24) ha
s proper nip pressure.
• Ensure that connectors P/J412A, P/J4
17A and P/J150 are seated correctly on the IOT
Drive PWB and the Duplex In Sensor, and there are no obvious crimped or broken wires.
Procedure
NOTE: In the following step, to block the Duplex In Sensor, open the Inverter Door. Slide a
sheet of paper up, and under, the mylar guides at the bottom of the Inverter 1 Upper Chute.
Enter dC330 010-130 Duplex In Sensor. Press Start. O
pen the Inverter Cover and block the
Duplex In Sensor with a sheet of paper. The display changes from L to H.
YN
There display is a constant H.
YN
Go to Fl
ag 3 on BS
D 10.10 and check the harness for an short circuit. If the harness
is good, replace the Duplex In Sensor (PL 2.24).
Connect the meter from P/J4
12A-5 on the IOT PWB to GND. Block the Duplex In Sen-
sor. The voltage at P/J412A-5 go
es from less than +1.0 VDC when the sensor is not
blocked, to +5 VDC when the sensor is blocked.
YN
There is +5 VDC between P
/J412A-
6 and P/J412A-4 on the IOT Drive PWB.
YN
Go to F
lag 4 on BSD 10.10 and check the harness for a short circuit. If the har-
ness
is good, replace the IOT Drive PWB (PL 9.
2).
Go to Flag 3 and Flag 4 on BSD 10.10 and check the harness for an open circuit. If
th
e harness is good, replace the Duplex In Sensor (PL 2.24). If the problem contin-
ues, replace the IOT Drive PWB (PL
9.2).
Replace t
he IOT Drive PWB (PL 9.2).
Ent
er dC330 010-025 Inverter Roll Solenoid Nip. Pre
ss Start. The Release Solenoid ener-
gizes.
YN
+24 VDC is measured between P/
J412A-14 an
d GND.
YN
+24 VDC is measured between P/
J412A-13 and
GND.
YN
Replace the IOT Drive PWB (PL 9.
2).
Go
to Flag 4 on BSD 10.8 and check the harness for an open circuit. If the harness is
good, replac
e the Release Solenoid (PL 2.24).
Press Start. Th
e voltage at P/J412A-14 momentarily goes to approximately +12 to
+15 VDC then returns to +24 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace the Release Solenoid (PL 2.24).
Ente
r dC330 010-026 Inverter Roll Solenoid Release. Pre
ss Start. The Release Solenoid
energizes.
YN
+24 VDC is measured between P/
J412A-12 and
GND.
YN
Go to F
lag 5 on BSD 10.8 and check the harness for an open circuit. If the harness is
good, replac
e the Release Solenoid (PL 2.24).
Press Start. Th
e voltage at P/J412A-12 momentarily goes to approximately +12 to
+15 VDC then returns to +24 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace the Release Solenoid (PL 2.24).
Ente
r dC330 010-020 Inverter Motor Forward. Pre
ss Start and Stop several times. The
Inverter Motor energizes and deenergizes.
YN
Press St
op. +24 V
DC is measured between P/J417A-13, 14, 17, 18 on the IOT Drive
PWB and GND.
YN
+24 VDC is measured between P/
J417A-15 on
the IOT Drive PWB and GND.
YN
Replace the IOT Drive PWB (PL
9.
2).
Go to Flag 4 and Fl
ag 5 on BSD 10.9 and check the harness and connectors. If the
harness and connectors are OK, replace the Inverter Motor (PL 2.24).
Press Start. Th
e voltage at P/J417A-13, 14, 17, 18 on the IOT Drive PWB goes to
approximately +18.5 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace the Inverter Motor (PL 2.24).
Ent
er dC330 010-021 Inverter Motor Reverse. Pr
ess Start and Stop several times. The
Inverter Motor energizes and deenergizes.
YN
Replace the IOT Drive PWB (PL
9.2).
Check
for obvious damage, missing and/or broken Drive Motor gear as
semblies and drive
belts that would cause the paper to be slow to actuate the Duplex In Sensor.
