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.
YN
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).
YN
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.
YN
Press Stop. +24 VDC is measured between P/J553-3 and GND on the Tray Module
PWB.
YN
+24 VDC is measured at P/J555-3 on the Tray Module PWB.
YN
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.
YN
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 approximately +22 VDC. The voltage at P/J553 pins 1, 2, 5, and 6
all drop to approximately +22 VDC when [008-048] is entered.
YN
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).
