Vacuum the Black Dispense Housing. Reinstall the Black Toner Cartridge. Enter
dC330. Stack the codes [009-031 Dispense Motor K] and [009-255 Low Toner Sen-
sor K].
The sensor changes state as toner is dispensed.
Y N
+5 VDC is measured between
P/J433A
-3 and P/J433A -1.
Y N
Go to +5VDC Wirenets ( Figure 1 ) and check the wires between P/J21 -1
on the IOT LVPS and P/J117 -1 on the Low Toner Sensor (K).
Go to DC COM (+5V RET) Wirenets and check the wires between P/J21 -
5 on the IOT LVPS and P/J117 -3 on the Low Toner Sensor (K).
Go to Flag 3 on BSD 9.4 and check the wire for a short circuit to ground. Check
the wires between P/J117 -1and P/J433A -3 and between P/J117 -3 and P/
J433A -1 for an open circuit. If the wires are good, replace the Low Toner (K)
Sensor ( PL 6.3 ).
This should resolve the problem. Ensure that there is no blockage in the dispense
area. Check the machine for proper operation.
The sensor indicates that toner is present in the Toner Dispense Housing and is being dis-
pensed. Replace the IOT Drive PWB (
PL 9.2 ).
Replace the Black Toner Cartridge (Section 6, Machine Consumables ).
9-358 Cleaning Auger Full RAP
The Control Logic has determined that 130 copies have been made since the Cleaning Auger
Stopped.
Initial Actions
• Refer to BSD 9.13 and BSD 9.15 for the following procedure.
• Ensure that P/J418B on the IOT Drive PWB and P/J115 0n the Auger Sensor are con-
nected.
• Check that the Auger sensor is clean and properly installed.
Procedure
Enter dC330 009-248 Waste Auger Rotate Sensor. Press Start. The Display is (H)
Y N
Check the Auger Sensor for intermittent operation. If there is intermittent operation,
replace the Auger Sensor (
PL 5.5 ). If the problem continues, replace the IOT Drive PWB
( PL 9.2 ).

+5 VDC is measured between P/J418B -2 and GND on the IOT Drive PWB.
Y N
Replace the IOT Drive PWB ( PL 9.2 ).
+5 VDC is measured between P/J418B -3 and P/J418B -1 on the IOT Drive
PWB.
Y
N
Go to the +5 VDC (IOT) Wirenet and check the wires between P/J21
-1 on the
IOT LVPS and P/J418B -3 on the IOT Drive PWB. Go to the DC COM (IOT)
Wirenet and check the wires between P/J21 -5 on the IOT LVPS and P/J418B -
1 on the IOT Drive PWB.
Go to Flag 5 on BSD 9.13. Check the wires for an open circuit. If the wires are good,
replace the Auger Sensor ( PL 5.5 ).
Clean the Waste Toner Junction. If large particle of fused toner are present, replace the
Waste Toner Junction (
PL 5.5 ).
Replace the Waste Toner Bottle and clean the Waste Toner Junction (Section 6, Machine Con-
sumables ).
