Status Indicator RAPs Initial issue
8-151 Tray 3 Takeaway Sensor On (TTM)
The Takeaway Sensor does not detect paper fed from Tray 3.
Initial Actions
• Check condition and specification of paper in Tray 3.
• Check the paper path and sensor area for obstructions.
• Check for wear and clean the Tray 3 Feeder Roll, Takeaway Roll and the Pinch Roll.
• Check that the Left Cover is properly latched and that the Interlock Actuator is not dam-
aged.
Procedure
Open the Left Cover and cheat the Left Cover Interlock Switch ( PL 16.13 ). Enter dC330 [008-
106] and press Start . Block and unblock the Takeaway Sensor ( PL 16.6 ). The display
changes state.

Press Stop . Check the circuit of the Takeaway Sensor ( Figure 1 ). Refer to the OF 99-2
RAP for troubleshooting procedure.
Press Stop . Enter dC330 [008-036] and press Start . Both Takeaway Rolls ( PL 16.6 ) rotate.

Takeaway Motor 1 (
PL 16.15 ) energizes.

Press Stop . +24 VDC is measured between P/J552 -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/J552 : Pin 1, 2, 5, and
6.

Refer to Figure 2 . Check the wires from the Tray Module PWB to the Takeaway
Motor 1 for an open circuit. If the wires are good, replace the Takeaway Motor 1
(
PL 16.15 ).
With dC330 [008-036] still entered, press Start and check that the voltage at P/J552
pins 1, 2, 5, and 6 each drop to approxi22 VDC. The voltage at P/J552
pins 1, 2, 5, and 6 all drop to approxi22 VDC when [008-036] is entered.

N
Replace the Tray Module PWB ( PL 16.15 ).
Replace the Takeaway Motor ( PL 16.15 ).
Press Stop . Check the Takeaway Motor 1 and its associated gears ( PL 16.15 ) for dam-
age, contamination or misalignment.
Press Stop .
• Ensure that the Chutes ( PL 16.6 ) are properly seated and not damaged.
• Ensure that the connectors shown in the circuit diagrams ( Figure 1 , Figure 2 ) are securely
connected and that the wires are not damaged.
• Replace the Takeaway Sensor ( PL 16.6 ).
• If the problem persists, replace the Tray Module PWB ( PL 16.15 ).
