Initial Issue
005-121 DADF Feed Out Sensor On Jam RAP
BSD-ON:
BSD 5.5 - Document Feed (2 of 2)
After feeding started (DADF Feed Motor On (CW)) in Duplex, the DADF Feed Out Sensor did
not turn ON within the specified time.
NOTE: When turning the power OFF, turn OFF the power switch first and then the main power
switch.
Procedure
Remove the DADF Rear Cover and open the Top Cover. Enter the Diag Mode, turn ON
Com-
ponent Control
[005-205]. Activate the Actuator of the DADF Feed Out Sensor manually.
Does the display change between High/Low?
Y
N
Disconnect the DADF Feed Out Sensor connector
P/J772
. Is High displayed?
Y
N
Check the wire between the DADF Feed Out Sensor
P/J772
-2 and the DADF PWB
P/J757
-5 for a short circuit. If no problems are found, replace the DADF PWB (
PL
51.2
).
Is the voltage between the DADF Feed Out Sensor
P/J772
-1 (+) and
P/J772
-3 (-)
+5VDC?
Y
N
Check the wires between the DADF PWB
P/J757
-6 and the DADF Feed Out Sensor
P/J772
-1, as well as between the DADF PWB
P/J757
-4 and the DADF Feed Out
Sensor
P/J772
-3 for open circuits and poor contacts.
Replace the DADF Feed Out Sensor (
PL 51.6
).
Press the Stop button. Turn ON
Component Control
[005-010] (DADF Feed Motor). Does the
DADF Feed Motor operate?
Y

Is the voltage between the DADF Feed Motor
P/J776
-5/2 (+) and the GND (-)
+24VDC?
Y
N
Is the voltage between the DADF PWB
P/J754
-B1/B2 (+) and the GND (-)
+24VDC?
Y
N
Is the voltage between the DADF PWB
P/J753
-2 (+) and the GND (-)
+24VDC?
Y
N
Refer to
BSD 5.1 - Document Setting
and check the +24VDC circuit to the
DADF PWB
P/J753
-2.
Replace the DADF PWB (
PL 51.2
).
Check the wires between the DADF PWB
P/J754
-B1 and the DADF Feed Motor
P/
J776
-5, as well as between the DADF PWB
P/J754
-B2 and the DADF Feed Motor
P/J776
-2 for an open circuit and poor contact.
Turn OFF the power and disconnect
P/J754
from the DADF PWB.
Measure the wire wound resistance of the Motor.
•
Between
P/J754
pin-B1 and
P/J754
pin-B5/B6
•
Between
P/J754
pin-B2 and
P/J754
pin-B3/B4
Is the resistance approximately 1Ohm for each?
Y
N
Replace the DADF Feed Motor (
PL 51.5
).
Replace the DADF PWB (
PL 51.2
).
Check the following:
•
The document path for foreign substances.
•
The DADF Feed/Nudger Roll for contamination, wear or revolution failure.
•
The DADF Feed Out Sensor Actuator for disengagement, drag and damage.
