7-283 Tray 3 Lift Motor Failure RAP
The Tray 3 Stack Height Sensor (PL 2.5) failed to change state within the specified time after
Tray 3 Feed/Lift Motor was energized.
Initial Actions
• Refer to BSD 7.7 and BSD 7.10 for the following procedure.
• Ensure there is paper loaded in the Tray 3.
• Ensure connector P/J803 on the T
ray PWB is properly seated (PL 9.2).
• Check for crimped or broken wires to connecto
rs on the IOT Drive PWB (PL 9.2).
• Pull out Paper Tray 3.
• Open the Lower Left Door (PL 2.
8).
• Remove the Screw and open the Tray 3 Feed Assembly (PL 2.4).
Procedure
Cheat the L/H Cover INTLK Switch. Remove the Tray 3 Feed Assembly without disconnecting
P/J793. Enter dC330 008-223 Tray 3 Level Sensor. Press Start. Manually actuate the Tray 3
Stack Height Sensor. The display changed from H to L.
YN
+0 VDC is measured at P
/J415A-
12 on the IOT Drive PWB.
YN
+5 VDC is measured at P
/J130
-2 on the Tray 3 Stack Height Sensor.
YN
Go to F
lag 5 and Fl
ag 6 on BSD 7.7 and check the harness and connectors. If
the harness and connectors are OK, replace the IOT Drive PWB.
+5 VDC is measured between P/J13
0-1 and P/J130-3 on the Tray 3 Stack
Height Sensor.
YN
+5 VDC is measured between P/
J21-
1 and P/J21-5 on the IOT LVPS.
YN
Go to the +
5
VDC Power (IOT LVPS) RAP.
+5 VDC is measured between P/J803B-11 o
n the Tray PWB and P/J21-5
on the IOT LVPS.
YN
Replace the IOT Drive PWB (PL 9.
2).
Go
to Flag 5 on BSD 7.7 and check wires for an open circuit. If the wires are
OK
, replace the Tray PWB (PL 9.3).
Replace the Tray 3 Stack Height Sensor (PL 2.5).
Go to Flag 6 on BS
D 7.7 and check wires for an open circuit. If the wires are OK, replace
the IOT Drive PWB (PL 9.2).
Enter dC330 008-017 Tray 3 Feed/Lift Motor (Lift), 008-018 Tray 3 Feed/Lift Motor (Feed)]
Tr
ay 3 Feed/Lift Motor. Press 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/
J803B-14 and
GND on the Tray PWB.
YN
Check the fuse on the Tray PWB. Fuse is OK.
YN
Replace fuse (PL
9.
3).
+24 VDC is measured between P/J23-3
and GND on the IOT LVPS.
YN
Go to the +
24 V
DC Power (IOT LVPS) RAP.
Go to Flag 4 on BS
D 7.7 and check the harness and connectors. If the harness and
connectors are OK, replace the Tray 3 Feed/Lift Motor (PL 2.6).
+24 VDC is measured between P/J803B-15 and
GND on the Tray PWB.
YN
Check the fuse on the Tray PWB. Fuse is OK.
YN
Replace fuse (PL
9.
3).
+24 VDC is measured between P/J23-3
and GND on the IOT LVPS.
YN
Go to the +
24 V
DC Power (IOT LVPS) RAP.
Go to Flag 3 on BSD 7.7 and check the wires and connectors. If the wires and con-
nectors
are OK, replace the Tray 3 Feed/Lift Motor (PL 2.6).
Go
to Flag 3 and Fl
ag 4 on BSD 7.7 and check the wires and connectors. If the wires and
connectors are OK, replace the Tray 3 Feed/Lift Motor (PL 2.6). If the problem continue
place the Tray PWB (PL 9.2).
Enter dC330 008-233 Tray 3 No Paper Sensor. Pr
ess Start. Manually actuate the Tray 3 No
Paper Sensor. The display changed from H to L.
YN
+0 VDC is measured at P
/J803B-
7 on the IOT Drive PWB and GND.
YN
+5 VDC is measured at P
/J129-
2 on the Tray 3 No Paper Sensor.
YN
Go to F
lag 1 and Fla
g 2 on BSD 7.7 and check the harness and connectors. If
the harness and connectors are OK, replace the IOT Drive PWB.
+5 VDC is measured between P/J129-1
and P/J129-3 on the Tray 3 No Paper
Sensor.
YN
+5 VDC is measured between P/
J21-1 an
d P/J21-5 on the IOT LVPS.
