The Tray 4 Feed Out Sensor does not turn ON within the specified time after the Feed from
Tray 4 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 4. Turn the power ON and enter the Diag mode. Turn ON
[074-001] (Tray 4 Feed/Lift Motor). Does the Tray 4 Feed/Lift Motor rotate?

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 4 Feed/Lift Motor wire wound resistance.
Check the resistance of the following.
•
Between the Tray Module PWB
•
Between the Tray Module PWB P/J555-7 and P/J555-8
Is the resistance approx. 4Ohm for each? (When the temperature is 25 °C)
Y
N
Check the connection between the Tray Module PWB
Lift Motor
P/J223
for open circuit, short circuit, and poor contact. If there are no
problems, replace the Tray 3 Feed/Lift Motor
Measure the resistance between the Tray Module PWB P/J555-5/6/7/8 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

Use to check the Tray 4 Feed Out Sensor
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 4 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 4 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
