BSD-ON:9.15 Toner Dispense Control (1 Of 3) BSD, CH9.16
Yellow Dispense failure.
Procedure
Enter the Diagnostics. Enter DC330 [093-006] (Yellow Dispense Motor). Select Start. Dispense
Motor is heard rotating. (ON duration is 2 sec.)
Y N
Open the PWB Chassis. (REP2.1.1) +24VDC is measured between P/J430-8 (+) on
the IOT PWB and GND (-).
Y N
Refer to BSD CH2.2, check the +24VDC circuit to P/J430-6 on the IOT PWB.
Turn off the power. Disconnect Connectors P/J201Y on the Dispense Motor. Measure the
wire-wound resistance of the Dispense Motor. The resistance between P/J201Y-1 and
-2 pins is between 22.0 and 27.0 ohms.
Y N
Replace the Yellow Dispense Motor (PL6.4).
Check the following for continuity:
�6�1 IOT PWB P/J436-A14 to Dispense Motor J201Y-1
�6�1 IOT PWB P/J436-A13 to Dispense Motor J201Y-2
Every resistance is 1 ohm or less.
Y N
Check any wire with more than 1 ohm for an open wire or poor contact.
Perform the following:
�6�1 Disconnect and reconnect the cable between P/J432 on the IOT PWB and P/J402
on the MCU PWB.
�6�1 Remove the Yellow Toner Dispenser. (REPX.X) Check that there is no such load as
poor Auger rotation, toner blocking and Drive gears binding.
If no problem is found, replace the Flexible Print Cable (PL 11.1), IOT PWB (PL 11.1) and
MCU PWB (PL 11.1) in that order.
+5VDC is measured between Connectors P/J653A-1 (+) and -2 (-) on the Low Toner
Sensor PWB.
Y N
+5VDC is measured between P/J414-B4 (+) and -B5 (-) on the MCU PWB.
Y N
+5VDC is measured between P/J400-2 (+) on the MCU PWB and GND (-).
Y N
Refer to BSD CH2.2, check the +5VDC circuit to P/J400-2 on the MCU PWB.
Replace the MCU PWB (PL11.1).
Check the wires between P/J414-B4 on the MCU PWB and Connector P/J653A-2, and
between P/J414-B5 on the MCU PWB and Connector P/J653A-1 for an open wire or
poor contact.
Remove the Low Toner Sensor Y. There is any toner on the detection area of the Low
Toner Sensor.
Y N
Check for toner blocking, poor Auger rotation, gears binding, etc. Replace defective parts,
if any (PL 6.4).
Replace the Low Toner Sensor Y (PL 6.4).
