BSD-ON:9.15 Toner Dispense Control (1 Of 3) BSD, CH9.16
Magenta Dispense failure.
Procedure
Enter the Diagnostics. Enter DC330 [093-007] (Magenta 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/J201M on the Dispense Motor. Measure
the wire-wound resistance of the Dispense Motor. The resistance between P/J201M-1
and -2 pins is between 22.0 and 27.0 ohms.
Y N
Replace the Magenta Dispense Motor (PL6.4).
Check the following for continuity:
?IOT PWB P/J436-A12 to Dispense Motor P/J201M-1
?IOT PWB P/J436-A11 to Dispense Motor P/J201M-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:
?Disconnect and reconnect the cable between P/J432 on the IOT PWB and P/J402
on the MCU PWB.
?Remove the Magenta 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 J400-2 on the MCU PWB.
Replace the MCU PWB (PL 11.1).
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 J653A-1 for an open wire or poor
contact.
Remove the Low Toner Sensor M. 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 M (PL 6.4).
