7-287 Tray 5 Broken (Down) RAP
The Tray 5 Stack Down Sensor failed to change state within 3 seconds after the Tray 5 Feed/
Lift Motor Down was energized.
Initial Actions
• Refer to BSD 7.9 and BSD 7.10 for the following procedure.
• Ensure the Tray 5 top cover is closed.
• Ensure there is paper loaded in the Tray 5.
• Ensure connector P/J416A o
n the IOT Drive PWB is properly seated (PL 9.2).
• Check for crimped or broken wires to connecto
rs on the IOT Drive PWB (PL 9.2).
Procedure
Cheat the Tray 5 Switch. Enter dC330 008-226 Tray 5 (Bypass) Level up Sensor. Press
Start. Manually actuate the Tray 5 Stack Up Sensor. The display changed from H to L.
YN
+0 VDC is measured at P
/J416B-
6 on the IOT Drive PWB.
YN
+5 VDC is measured at P
/J145
-2 on the Tray 5 Stack Up Sensor.
YN
Go to Fl
ag 2 on BS
D 7.9 and check the harness and connectors. If the harness
and connectors are OK, replace the IOT Drive PWB.
+5 VDC is measured between P/J145-1 and
P/J145-3 on the Tray 5 Stack Up
Sensor.
YN
+5 VDC is measured between P/
J21-
1 and P/J21-5 on the IOT LVPS.

VDC Power (IOT LVPS) RAP.
+5 VDC is measured between P/J416
B-5 on the IOT Drive PWB and P/
J21-5 on the IOT LVPS.
YN
Replace the Tray 5 Stack Up Sensor (PL
2.
11).
Go to Flag 3 on BSD 7.9 and check wires for an open circuit. If the wires are
OK, r
eplace the IOT Drive PWB (PL 9.2).
Replace the Tray 5 Stack Up Sensor (PL 2.
11).
Replace the IOT Drive PWB (PL 9.2).
Cheat
the Tray 5 Switch. Enter dC330 008-2
27 Tray 5 (Bypass) Level Down Sensor. Press
Start. Manually actuate the Tray 5 Stack Down Sensor. The display changed from H to L.
YN
+0 VDC is measured at P
/J416B-
4 on the IOT Drive PWB.
YN
+5 VDC is measured at P
/J147
-2 on the Tray 5 Stack Down Sensor.
YN
Go to Flag 4 on BSD 7.9 and check the harness and co
nnectors. If the harness
and connectors are OK, replace the IOT Drive PWB.
+5 VDC is measured between P/J147-1 and
P/J147-3 on the Tray 5 Stack Down
Sensor.
YN
+5 VDC is measured between P/
J21-1 an
d P/J21-5 on the IOT LVPS.
YN
Go to the +
5 VD
C Power (IOT LVPS) RAP.
+5 VDC is measured between P/J4
16B-5 on the IOT Drive PWB and P/
J21-5 on the IOT LVPS.
YN
Replace the Tray 5 Stack Down Sensor (PL 2.
12).
Go to
Flag 1 on BS
D 7.9 and check wires for an open circuit. If the wires are
OK, replace the IOT Drive PWB (PL 9.2).
Replace the Tray 5 Stack Down Sensor (PL 2.12).
Replace the I
OT Drive PWB (PL 9.2).
Ent
er dC330 008-042 Tray 5 Lifter Motor CW. P
ress Start and Stop several times.
CAUTION
Do not operate the component control more than twice before resetting paper position. To
lower the paper f
rom the feed position, pull out respective tray. If the tray is overdriven, it will be
hard to pull out and may cause component damage.
The Feed/Lift Motor energizes and deenergizes.
YN
+24 VDC is measured between P/
J416B-20 and
GND on the IOT Drive PWB.
YN
+24 VDC is measured between P/
J23-3
and GND on the IOT LVPS.
YN
