BSD 8.3 - Paper Transportation (Tandem Tray Module)
BSD-ON:
BSD 8.4 - Tandem Tray Module Takeaway Drive
The Tray 3 Feed Out Sensor does not turn ON within the specified time after the Feed from
Tray 3 has started.
NOTE: When turning the power OFF, turn OFF the power switch first and then the main power
switch.
Initial Actions
•
Check F4 on the Tray Module PWB for an open.
•
Go to the +24VDC-2
IOT wirenets
. Check the connection between the MCU PWB
P423
-
2 and the Tray Module PWB
P/J541
-8 for open circuit, short circuit, and poor contact.
Procedure
Remove Tray 3. Turn the power ON and enter the Diag mode. Turn ON
Component Control
[073-001] (Tray 3 Feed/Lift Motor). Does the Tray 3 Feed/Lift Motor rotate?
Y
N
Go to the +24VDC-2
IOT wirenets
. Is the voltage between the Tray Module PWB P/J
541-8 (+) and the GND (-) +24VDC?
Y
N
Go to +24VDC Power RAP.
Turn the power OFF, then measure the Tray 3 Feed/Lift Motor wire wound resistance.
Check the resistance of the following.
•
Between the Tray Module PWB
P/J555
-1 and
P/J555
-2
•
Between the Tray Module PWB
P/J555
-3 and
P/J555
-4
Is the resistance approx. 4Ohm for each? (When the temperature is 25
°
C)
Y
N
Check the connection between the Tray Module PWB
P/J555
and the Tray 3 Feed/
Lift Motor
P/J222
for open circuit, short circuit, and poor contact. If there are no
problems, replace the Tray 3 Feed/Lift Motor (
PL 11.9
).
Measure the resistance between the Tray Module PWB
P/J555
-1/2/3/4 and the Frame.
Is the resistance infinite for all?
Y
N
Check the wires of the pins with non-infinite resistance for peeled-off coatings and
short circuits due to pinching.
Replace the following parts in sequence:
•
Tray Module PWB (
PL 11.13
)
•
MCU PWB (
PL 18.2
)
•
Press the Stop button. Turn ON
Component Control
[077-033] (TM Takeaway Motor).
Does the TM Takeaway Motor rotate?
Y
N
Is the voltage between the TM Takeaway Motor
P/J224
-2/5 (+) and the GND (-)
+24VDC?
Y
N
Go to +24VDC Power RAP.
Turn the power OFF, disconnect the TM Takeaway Motor connector
P/J224
.
Measure the TM Takeaway Motor wire wound resistance.
•
Between the TM Takeaway Motor
P/J224
-2 and
P/J224
-1
•
Between the TM Takeaway Motor
P/J224
-2 and
P/J224
-3
•
Between the TM Takeaway Motor
P/J224
-5 and
P/J224
-4
•
Between the TM Takeaway Motor
P/J224
-5 and
P/J224
-6
Is the resistance approx. 0.85Ohm for each? (When the temperature is 25
°
C)
Y
N
Replace the TM Takeaway Motor (
PL 11.5
)
Measure the resistance between the disconnected TM Takeaway Motor connectors
P/
J224
-1/3/4/6 and the Frame. Is the resistance infinite for all?
Y
N
Check the wires of the pins with non-infinite resistance for peeled-off coatings and
short circuits due to pinching.
Check the connection between the Tray Module PWB
P/J554
and the TM Takeaway
Motor
P/J224
for open circuit, short circuit, and poor contact. If no problems are found,
replace the following parts in sequence:
•
Tray Module PWB (
PL 11.13
)
•
MCU PWB (
PL 18.2
)
Press the Stop button and open the L/H Cover. Turn ON
Component Control
[073-103] (Tray 3
Feed Out Sensor). Move the Actuator manually to block/clear the light path to the Tray 3 Feed
Out Sensor.
Does the display change between High/Low?
Y
N
Use to check the Tray 3 Feed Out Sensor (
PL 11.7
).
Press the Stop button and turn the power OFF. Check the following:
•
A paper transportation failure due to a foreign substance/burr on the paper path
•
The Feed Roll, Retard Roll, and Nudger Roll for contamination, wear, and revolution fail-
ure
•
The Takeaway Roll 3 and Pinch Roll for contamination, wear, and revolution failure
•
The Feed Roll, Retard Roll, and Nudger Roll Drive Gears for wear and damage
•
The Takeaway Roll 3 Drive Gear for wear and damage
•
Use of paper out of spec
If no problems are found, replace the following parts in sequence:
•
Reload the machine software (
GP 16
).
•
Tray Module PWB (
PL 11.13
)
•
MCU PWB (
PL 18.2
)
