9-357 Black Toner Dispenser Broken RAP
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/J4
32 and P/J433B on the Dispense PWB, P/J421B on the IOT DRIVE PWB, P/
P/J213 on the Black Cartridge Motor, and P/J117 on the Black Low Toner Sensor are con-
nected before beginning this RAP.
NOTE: If the code doesn’t clear and the auger isn’t broken, go to NVM 776-063 and set the
value t
o 0.
Then, go to NVM 776-371 Toner Cartridge K Empty and set the value to 0.
Procedure
Check the Black Toner Cartridge. The toner cartridge is empty.
YN
NOTE: The Cartridge Motor is only energized for 10 seconds each time Star
t 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 ac
curate
reading.
Remove the Black Toner Cartridge to see the Toner Cartridge Coupling. Cheat the Front
Door Int
erlock. Enter dC330 009-011 Cartridge Motor K. Press Start. The Toner Car-
tridge Motor K operates.
YN
+12 VDC is measured at P/
J433B-12 and
at P/J433B-10 on the Dispense PWB.
YN
+24 VDC is measured between P
/J431-
2 and P/J431-1 on the Dispense
PWB.
YN
Go to +24V
DC Wi
renets 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-2 and
GND on the IOT Drive PWB
when the display indicates Off.
YN
Go to Fl
ag 1 on B
SD 9.4. Check the wire for an open or a short circuit. If
the wire is good, replace the Dispense PWB (PL 6.4). If the problem con-
tinues, replace the IOT Drive PWB (PL 9.2)
Press Start. Th
e voltage momentarily goes to less than +1 VDC
YN
Replace the IOT Drive PWB (PL 9.
2)
Replace t
he Dispense PWB (PL 6.4)
Go to Flag 2 on BSD 9.
4. Check the wires for an open circuit or a short circuit. If the
wires are good, replace the Cartridge Motor (K). (PL 6.3)
NOTE: The Dispense Motor is only energized for 10 seconds each time Star
t is pressed.
The display will indicate Off when the 10 seconds have expired. Pressing Start will ener-
gize the Dispense Motor for another 10 seconds. Press
St
art as often as necessary to get
an accurate reading.
Enter dC330 009-031 Dispense Motor K. Press Star
t. Watch the Dispense and Conveyor
Gears to see if they rotate. The Toner Dispense Motor (K) operates.
YN
+12 VDC is measured at P
/J434-
8 and at P/J434-7 on the Dispense PWB.
YN
+24 VDC is measured between P
/J431-2
and P/J431-1 on the Dispense
PWB.
YN
Go to +24VDC W
irenet
s and check the wires between P/J24-2 on the IOT
LVPS and P/J431-2 on the Dispense PWB.
Go to D
C 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-1 and
GND on the IOT Drive PWB
when the display indicates Off.
YN
Go to F
lag 1 on BSD 9.6. Check the wire for an open or a short circuit. If
th
e wire is good, replace the Dispense PWB (PL 6.4). If the problem con-
tinues, replace the IOT Drive PWB (PL 9.
2)
Pr
ess Start. Th
e voltage momentarily goes to less than +1 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2)
Replace the Dispense PWB (PL 6.4)
Go to Flag 2 on BS
D 9.6 and check the wires for an open circuit. If the wires are OK,
check the toner dispense gears (PL 6.3) and (PL 6.4) for damage. If the gears are
OK, replace the Toner Dispense Motor K (PL 6.3). If the problem continues, replace
the Toner Dispense Assembly K (PL 6.4).
Reinstall the Black Toner Cartridge. Enter dC330. Stack the codes [009-031 Dispense
Mot
or
K] and [009-255 Low Toner Sensor K]. The sensor changes state as toner is
disp
ensed.
YN
Connect the meter between P/
J432-4 and
GND. The meter reads a constant +5
VDC.
YN
Go to F
lag 3 on BSD 9.4 and check the wire for an open circuit or a short circuit
to
ground. If the wire is good, replace the Low Toner (K) Sensor (PL 6.3). If the
problem continues, replace the IOT Drive PWB (PL 9.2).
