Initial issue
7-271 Tray 2 Paper Size Sensor
An abnormal AD value was detected by the Tray 2 Paper Size Sensor.
Initial Actions
• Check that the paper size setting is correct.
• Check the Tray 2 Paper Size Sensor for damage or incorrect mounting. Repair or replace
as required.
• Check the switch actuators on Tray 2 for wear or damage. Repair or replace as required
Procedure
The machine is equipped with a 3TM.
YN
Ensure that Tray 2 is closed. The voltage measured a P/J546-8 on the Tray Module
PWB (PL 16.15) corresponds to the paper size in Table 1.
YN
There is +5 VDC from P/J816-1 to P/J816-3 on the Tray 2 Paper Size Sensor
(PL 16.1).
YN
There is +5VDC from P/J546-9 to P/J546-7 on the Tray Module PWB.
YN
Go to the +5VDC Wirenets (Figure 4) to troubleshoot the power circuit.
Go to Figure 1. Check the wires from P/J546 to P/J816.
Go to Figure 1. Check the wire from P/J546-8 to P/J816-2. If the wire is OK, replace
the Tray 2 Paper Size Sensor (PL 16.1).
• Replace the Tray 2 Paper Size Sensor (PL 16.1).
• If the problem continues, replace the Tray Module PWB (PL 16.15).
Ensure that Tray 2 is closed. The voltage measured at P/J546-8 on the Tray Module PWB
(PL 15.9) corresponds to the paper size in Table 1.
YN
There is +5VDC from P/J816-1 to P/J816-3 on the Tray 2 Paper Size Sensor (PL
15.1).
YN
There is +5VDC from P/J546-9 to P/J546-7 on the Tray Module PWB.
YN
Go to the +5VDC Wirenets (Figure 4) to troubleshoot the power circuit.
Go to Figure 2. Check the wires from P/J546 to P/J816.
Go to Figure 2. Check the wire from P/J546-8 to P/J816-2. If the wire is OK, replace the
Tray 2 Paper Size Sensor (PL 15.1).
• Replace the Tray 2 Paper Size Sensor (PL 15.1).
• If the problem continues, replace the Tray Module PWB (PL 15.9).
