9-370 Rotary Release Fail Rap - Xerox DocuColor 12/DCCS50 Service Manual

9-370 Rotary Release Fail RAP

The Control Logic has detected that the Rotary Latch Solenoid failed to unlock
Initial Actions
Refer to BSD 9.2 and BSD 9.15 for the following procedure.
Ensure that P/J412A and P/J418A on the IOT Drive PWB,
noid, and P/J116 on the Rotary Latch Sensor are connected before beginning this RAP.
Procedure
Enter dC330 009-237 Rotary Lock Mech Sensor. Press Start. The Display is (L)

+0 VDC is measured between P/J418A-4 and GND on the IOT Drive PWB.
Y N
+5 VDC is measured between P/J418A-5 and P/J418A-3 on the IOT Drive
PWB.
Y N
Go to the +5 VDC (IOT) Wirenet and check the wires between P/J21-1 on
the IOT LVPS and P/J418A-5 on the IOT Drive PWB. Go to the DC COM
(IOT) Wirenet and check the wires between P/J21-5 on the IOT LVPS and
P/J418A-3 on the IOT Drive PWB.
Go to Flag 5 on BSD 9.2 and check the wire for an open. Go to the +5 VDC
(IOT) Wirenet and check the wires between P/J116-1 on the Rotary Latch Sen-
sor and P/J418A-5 on the IOT Drive PWB. Go to the DC COM (IOT) Wirenet
and check the wires between P/J116-3 on the Rotary Latch Sensor and
J418A-3 on the IOT Drive PWB. If the wires are good, replace the Rotary Latch
Sensor (PL 6.1).
Replace the IOT Drive PWB (PL
Enter dC330 009-018 Rotary Lock Mech Latch. Press Start. The Rotary Latch Sole-
noid releases.

+24 VDC is measured between P/J412A-2 and P/J412A-1 on the IOT Drive
PWB.

Go to Flag 2 on BSD 9.2. Check the wires for an open circuit or a short circuit. If
the wires are good, replace the IOT Drive PWB

Go to Flag 2 on BSD 9.2 and check the wires for an open circuit. If the wires are
good, replace the Rotary Latch Solenoid
Check the Rotary Latch Solenoid for binding or intermittent operation. If the Rotary Latch
Solenoid is good, replace the Rotary Latch Sensor
