9-345/9-435 IBT Cleaner Retract Fail RAP
The Control Logic has detected that the IBT Clean Blade failed to retract from the IBT.
Initial Actions
• Refer to BSD 9.11 and BSD 9.15 for the following procedure.
• Ensure that P/J417A and P/J418B on the IOT Drive PWB, P/J252 on the Cleaner
Retract Clutch, and P/J111 on the IBT Clean Blade Home Position Sensor are connected
before beginning this RAP.
Procedure
Stack the dC330 codes 4-007 and 9-067. Enter dC330 009-216 IBT Cleaner Retract Home
Sensor. Press
Start. The Display is (L)
Y N
Remove the IBT REP 7.1.1 (Reinstall IBT after test is completed). Manually unblock the
IBT Clean Home Position Sensor. The display changes to (L)
Y N
+0 VDC is measured between
P/J418B -5 and GND on the IOT Drive PWB.
Y N
+5 VDC is measured between
P/J418B 6 and P/J418B -4 on the IOT Drive
PWB.
Y

Go to the +5 VDC-3 Wirenet and check the wires between P/J21
-1 on the
IOT LVPS and P/J418B -6 on the IOT Drive PWB. Go to the DC COM (+5
V Ret.)-3 Wirenet and check the wires between P/J21 -5 on the IOT LVPS
and P/J418B -4 on the IOT Drive PWB.
Go to Flag 1 on BSD 9.11 and check the wire for an open circuit. Go to Flag 3
on BSD 9.11. Check the wires for an open circuit. If the wires are good, replace
the IBT Clean Blade Home Position Sensor (
PL 7.3 ).
Replace the IOT Drive PWB ( PL 9.2 ).
Enter dC330 009-059 2ND Belt Transfer Roll Retract. Press Start. Enter dC330 009-067
IBT Cleaner Retract. Press Start. The Cleaner Retract Clutch de-energizes.
Y N
+24 VDC is measured between
P/J417A -10 and GND on the IOT Drive PWB.
Y N
Go to Flag 2 on BSD 9.11. Check the wires for an open circuit or a short circuit.
If the wires are good, replace the IOT Drive PWB ( PL 9.2 ). If the problem con-
tinues, replace the Cleaner Retract Clutch ( PL 1.3 ).
Replace the Cleaner Retract Clutch ( PL 1.3 ).
Check the Cleaner Retract Clutch for binding or intermittent operation. If the Cleaner
Retract Clutch is good, replace the IBT Clean Blade Home Position Sensor (
PL 7.3 ). If the
problem continues, replace the Cleaner Retract Clutch ( PL 1.3 ).
Replace the IOT Drive PWB ( PL 9.2 ).
9-354 Yellow Toner Dispenser Broken RAP
This fault code appears when any one of the following conditions occurs: the Low Toner Sensor
detects that there is no toner for a period of 2 seconds; the low toner sensor detects that there
is no toner for a period of 500 seconds (approximately 8 minutes); or when the toner dispense
motor remains energized.
Initial Actions
Refer to BSD 9.4, 9.6 and BSD 9.15 for the following procedure.
Ensure that P/J432 , P/J433B , and P/J434 on the Dispense PWB, P/J421B on the IOT Drive
PWB, P/J214 on the Yellow Cartridge Motor and P/J118 on the Yellow Low Toner Sensor are
connected before beginning this RAP.
NOTE: If the code doesn’t clear and the auger isn’t broken, go to NVM 776-060 and set the
value to 0. Then, go to NVM 776-372 Toner Cartridge Y Empty and set the value to 0.
Procedure
Check the Yellow Toner Cartridge. The toner cartridge is empty.
Y N
NOTE: The Cartridge Motor is only energized for 10 seconds each time Start is pressed.
The display will indicate Off when the 10 seconds have expired. Pressing Start will ener-
gize the Cartridge Motor for another 10 seconds. Press Start as often as necessary to get
an accurate reading.
Remove the Yellow Toner Cartridge to see the Toner Cartridge Coupling ( PL 6.3 ). Cheat
the Front Door Interlock. Enter dC330 009-012 Cartridge Motor Y. Press Start. The Yel-
low Toner Cartridge Coupling rotates.
Y
N
Press Start. The Yellow Cartridge Motor operates.
Y N
+12 VDC is measured at
P/J433B
-9 and at P/J433B -7 on the Dispense
PWB.
Y
N
+24 VDC is measured between
P/J431
-2 and P/J431 -1 on the Dis-
pense PWB.
Y
N
Go to +24VDC Wirenets
and check the wires between P/J24 -2 on
the IOT LVPS and P/J431 -2 on the Dispense PWB.
Go to DC COM (24V RET) Wirenets and check the wires between
P/J23 -4 on the IOT LVPS and P/J431 -1 on the Dispense PWB.
+5VDC is measured between P/J421B -4 and GND on the IOT Drive
PWB when the display indicates Off.
Y
N
Go to Flag 4 on BSD 9.4. Check the wire for an open or a short cir-
cuit. If the wire is good, replace the Dispense PWB ( PL 6.4 ). If the
problem continues, replace the IOT Drive PWB ( PL 9.2 ).
Press Start. The voltage momentarily goes to less than +1 VDC.
