Initial issue
Status Indicator RAPs
4-341 IOT Logic Failure
MCU PWB cannot detect INTLK +5 VDC.
Initial Actions
•
Check that the Waste Toner Bottle and all four Drum Cartridges are seated correctly.
•
Check fault history for 9-925 faults. If this fault has occurred recently, go to the
9-925
RAP.
•
Check that the I/F PWB is securely connected to the MCU PWB at
P410
.
•
Reinstall the IOT software. Refer to the instructions on the s/w install CD.
Procedure
There is +5VDC from
P/J535
-B13 on the I/F PWB to GND.
Y
N
There is +5VDC from
P/J631
-1 to GND.
Y
N
There is +5VDC from
P/J631
-3 to GND.

Go to
Figure 1
. Check the wire from
FS134
to
P/J631
-3 for an open circuit.
Go to
Figure 1
. Check the +5VDC INTLK wiring through the Drum connectors (
P/
J151
-
P/J154
). If the wires are OK, check the CRUM connectors on the Drum Car-
tridges for damage, wear, or contamination. Clean, repair, or replace as required
(
Machine Consumables
) (
PL 4.1
).
Go to
Figure 1
. Check for an open circuit between
P/J631
-1 and
P/J568
-2 on the Inter-
lock Relay PWB (
PL 9.1
). If this wire is OK, check for an open circuit between
P/J535
-
B13 and
P/J568
-1. If this wire is OK, replace the Interlock Relay PWB (
PL 9.1
).
There is +5VDC from
P/J401
-B20 to GND.
Y
N
There is +5VDC from
P/J400
-9 to GND.
Y
N
Go to
Figure 1
. Check the wire from J568-5 to J400 -9 for an open circuit. If the wire
is OK, replace the Interlock Relay PWB (
PL 9.1
).
Go to
Figure 1
. Check the four wires from J401 to
P/J526
-
P/J529
on the ROS for a
short circuit. If the wires are OK, replace the MCU PWB (
PL 13.1
). If the problem contin-
ues, replace the ROS (
PL 3.1
).
Go to
Figure 1
. Check the wires between the MCU PWB and the ROS for an open circuit or
loose connection:
•
J401-A1 to J527-1
•
J401-A2 to J526-1
•
J401-B19 to J528-1
•
J401-B20 to J529-1
If the wires are OK, replace the MCU PWB (
PL 13.1
). If the problem continues, replace the
ROS (
PL 3.1
).
