5-110 DADF Registration Sensor ON Dynamic Jam RAP

The DADF Registration Sensor did not actuate within 650 msec after the DADF Transport
Motor was energized.
Initial Actions
Check for the following:
• Obstructions in the document transportation path.
• Contamination on the DADF Registration Sensor.
• Sufficient normal force at the Nudger Rolls
• Nudger Rolls and Feed Rolls that are glazed or contaminated
• Ensure that connectors P/J599 and P/J580 are seated correctly on the DADF Control
PWB and DADF Registration Sensor and there are no obvious crimped or broken wires.
• Refer to BSD 5.1, 5.2, 5.3, 5.4 and 5.6 for the following procedure.
Procedure
Enter dC330 005-110 Regi Sensor. Press Start. Block the DADF Registration Sensor. The
display changed from L to H.
Y N
With paper at the DADF Registration Sensor, less than +1 VDC is measured at
J599-2 on the DADF Control PWB.
Y N
+5 VDC is measured between P/J599-1 and P/J599-3 on DADF Control PWB.
Y N
Go to Flag 5 on BSD 5.3. Check the wires for an open circuit or a short circuit. If
the wires are good, replace the DADF Control PWB
Go to Flag 1 and Flag 5 on BSD 5.3. Check the wires for an open circuit. If the wires
are good, replace the DADF Registration Sensor
Replace the DADF Control PWB (PL
Enter dC330 005-040 Feed Motor. Press Start. DADF Feed Motor cycles.
Y N
+24 VDC is measured between P/J598-7 and P/J598-8 on the DADF Control PWB
with the motor on.
Y N
Go to Flag 1 on BSD 5.2. Check the wires for a short circuit. If the wires are good,
replace the DADF Control PWB
+24 VDC is measured between P/J588-1 and P/J588-2 on the DADF Feed Motor
with the motor on.
Y N
Go to Flag 1 on BSD 5.2. Check the wires for an open circuit.
Check the in line fuse for an open circuit. If the fuse is good, replace the DADF Feed
Motor (PL 12.4)
Feed rolls turn.

+24 VDC is measured between P/J598-2 and P/J598-1 on the DADF Con-
trol PWB.
Y N
+24 VDC is measured between P/J550-3 and P/J550-1 on the DADF
Control PWB.
Y N
Go to the IIT/IPS +24VDC Wirenet and the DC COM (24V RET)
Wirenet. Check the wires between P/J550-2 and-1 on the DADF
Control PWB and P/J35-1 and -2 on the IIT/IPS LVPS, and the wires
P/
between P/J550-4 and-3 on the DADF Control PWB, and P/J35-5
and -6 on the IIT/IPS LVPS for an open circuit.
Replace the DADF Control PWB
Go to Flag 2 on BSD 5.2 and check the wires for an open circuit. If the wires are
good, replace the DADF Control PWB
Replace the Set Gate Solenoid
Enter dC330 005-011 Set Gate Solenoid

Y N
+24 VDC is measured between P/J598-2 and P/J598-1 on the DADF Control
PWB.
Y N
Replace the DADF Control PWB
+24 VDC is measured between P/J586-1 and P/J586-3 on the Set Gate Sole-
noid.
Y N
Go to Flag 2 on BSD 5.2 and check the wires for an open circuit or a short cir-
cuit. If the wires are good, replace the Set Gate Solenoid
