Status Indicator RAPs Initial issue
7-119 Tray 4 Misfeed (TTM)
The Tray 4 Feed Out Sensor does not detect paper after feeding from Tray 4.
Initial Actions
• Check condition and specification of paper in Tray 4.
• Check the paper path for obstructions.
• Check for wear and clean the Tray 4 Feeder Roll, Takeaway Roll and the Pinch Roll.
Procedure
Enter dC330 [008-103] and press Start . Block and unblock the Tray 4 Feed Out Sensor ( PL
16.5 ) by sliding Tray 4 in and out of the machine. The display changes.
Y N
Press Stop . Check the circuit of the Tray 4 Feed Out Sensor ( Figure 1 ). Refer to the OF
99-1 RAP for troubleshooting procedure.
Press Stop . Enter dC330 [008-007] and press Start . The Tray 4 Feed/Lift motor energizes
( PL 16.11 ).
Y N
Press Stop . Check the circuit of the Tray 4 Feed/Lift Motor ( Figure 2 ). Check the wires
from the Tray Module PWB to the Tray 4 Feed/Lift Motor for an open circuit. If the wires
are good, replace the Tray 4 Feed/Lift Motor (
PL 16.11 ). If the problem still exits, replace
the Tray Module PWB ( PL 16.15 ).
Press Stop . Remove the TTM Rear Cover ( PL 16.16 ). Enter dC330 [008-048] and press
Start . The Takeaway Motor 2 ( PL 16.15 ) energizes.
Y N
Press Stop . +24 VDC is measured between P/J553 -3 and GND on the Tray Module
PWB.
Y
N
+24 VDC is measured at
P/J555 -3 on the Tray Module PWB.
Y N
Refer to the +24 VDC Wirenets ( Figure 5 ). Check the +24 VDC to the Tray
Module PWB.
Replace the Tray Module PWB ( PL 16.15 ).
+24 VDC is measured at each of the following pins on P/J553 : Pin 1, 2, 5, and 6.
Y N
Refer to Figure 3 . Check the wires from the Tray Module PWB to the Takeaway
Motor 2 for an open circuit. If the wires are good, replace the Takeaway Motor 2 ( PL
16.15 )
With [008-048] still entered, press Start and check that the voltage at P/J553 pins 1, 2, 5,
and 6 each drop to approxi22 VDC. The voltage at P/J553 pins 1, 2, 5, and 6
all drop to approxi22 VDC when [008-048] is entered.
Y
N
Replace the Tray Module PWB ( PL 16.15 ).
Replace the Takeaway Motor 1 ( PL 16.15 ).
Press Stop .
• Check the Tray 4 Feed / Lift Motor and its associated gears ( PL 16.11 ) for damage, con-
tamination and misalignment.
• Check the Takeaway Motor 2 and its associated gears ( PL 16.15 ) for damage, contamina-
tion and misalignment.
• Check that the Tray 4 Upper and Lower Chutes ( PL 16.5 ) are properly seated and not
damaged.
• Ensure that the connectors shown in the circuit diagrams ( Figure 1 , Figure 2 , Figure 3 )
are securely connected and that the wires are not damaged.
• If these checks are OK, replace the Tray Module PWB ( PL 16.15 ).
