Go to Flag 1 on BSD 11.4. Check the harness for a short circuit to ground. If the har-
ness is good, replace the V-Tra Sensor ( PL 13.9 ).
+5 VDC is measured between P/J562 -7 and P/J562 -9

Go to the +5 VDC wirenet and troubleshoot the wires between P/J569 -1 and
P/J44 -6 on the Distribution PWB.
Replace the Mail Box Control PWB ( PL 13.10 ).
Go to Flag 1 and Flag 3 on BSD11.4. Check the harness for an open circuit. If the harness
is good, replace the Oct Exit Sensor ( PL 13.9 ).
With paper at the sensor, less than +0.5 VDC is measured between P/ P/J562 -8 and
GND.

Replace the V-Tra In Sensor ( PL 13.9 ).
Check the following parts for wear, glazing, or slipping.
•
Entrance Roll ( PL 13.9 )
• Pinch Rollers ( PL 13.9 )
• Exit Roll ( PL 13.9 )
• Drive Belt ( PL 13.10 )
Check the Drive Belt Tension Roll for proper tension.
11-143 V-Tra In Sensor Off Jam RAP
The V-Tra In Sensor did not deactuate within the specified time after the V-Tra In Sensor actu-
ated.
NOTE: If this machine has a Finisher/Sorter Accessory, go to Section 8D, 11-143 Mailbox
Entrance Sensor Off Jam RAP to troubleshoot this Fault Code.
Initial Actions
Refer to BSD 11.2 and 11.4 for the following procedure.
Check for the following:
•
Obstructions in the Mail Box paper path
• Bent or out of position paper chutes/guides in the Mail Box paper path
• Ensure that the Mail Box front Door is closed properly, in order to provide proper nip pres-
sure to the Vertical Transport Rolls.
• Ensure that connectors P/J562 on the Mail Box Control PWB and P/J567 on the V-Tra In
Sensor are seated correctly and there are no obvious crimped or broken wires.
Procedure
The trail edge of the paper is past the Oct Exit Sensor

Switch Off the Power. Disconnect P/J572
from the Mail Box Drive
Motor. Switch On the Power. +24 VDC is measured between P/
J572 -1 and P/J572 -2.

Go to Flag 1 on BSD11.2. Check the wires for an open circuit. If
the wires are good, replace the Mail Box Control PWB ( PL
13.10 ).
Replace the Mail Box Drive Motor ( PL 13.10 )
Press Stop . +5 VDC is measured between P/J572 -3 and GND.
Y N
Go to Flag 3 on BSD 11.2. Check the wire for an open circuit. If the
wire is good, replace the Mail Box Control PWB ( PL 13.10 ).
Press Start. Less than +1 VDC is measured between P/J572 -3 and
GND.
