9-369 Rotary Lock Fail Rap - Xerox DocuColor 12/DCCS50 Service Manual

9-369 Rotary Lock Fail RAP

The Control Logic has detected that the Rotary Latch Solenoid failed to lock
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 (H)

+5 VDC is measured between P/J418A-5 and P/J418A-3 on the IOT Drive
PWB.

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 a short circuit to ground. Go to
the +5 VDC (IOT) Wirenet and check the wires between P/J116-1 on the
Rotary Latch Sensor 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 P/J418A-3 on the IOT Drive PWB. If the wires are good,
replace the Rotary Latch Sensor

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

Check the Rotary Latch Solenoid for binding or intermittent operation. If the Rotary Latch
Solenoid is good, replace the Rotary Latch Sensor
