01H +12 Volt Circuits
NOTE: Before disconnection, switch off the machine,
GP 14
. Switch on the machine,
GP 14
, to
check CR15.
CR15 is OFF. Check the harnesses that follow for a short circuit, until CR15 is on,
Figure 1
.
1.
Disconnect PJ25 on the
LVPS
. CR15 is ON. Check from PJ25,
Flag 5
, to the power distri-
bution PWB,
WD 2
. If the harness from PJ25 to PJ131 is good. Reconnect PJ25 and per-
form the steps that follow:
a.
Disconnect PJ133 on the
power distribution PWB
. Check the harness,
Flag 9
, to
PJ130 on the
UI control PWB,
PL 2.10
.
b.
Disconnect PJ135 on the
power distribution PWB
. Check the harness,
Flag 10
, to
the
Scanner PWB
and
CCD PWB
(W/O
TAG 150
).
c.
Disconnect PJ138 on the
power distribution PWB
. Check the harness,
Flag 12
, to
PJ155 on the
riser PWB
,
PL 3.22 Item 3
.
01H +24 Volt Circuits
NOTE: Before disconnection, switch off the machine,
GP 14
. Switch on the machine,
GP 14
, to
check CR16.
CR16 is OFF. Check the harnesses that follow for a short circuit, until CR16 is on,
Figure 1
.
1.
Disconnect PJ18 on the
LVPS
. CR16 is ON. Check from PJ18 to the
ROS
,
PL 6.10 Item

,
WD 1
.
2.
Disconnect PJ19 on the
LVPS
. CR16 is ON. Check from PJ19,
Flag 4
, to the
tray 1 and 2
control PWB
,
WD 1
,
WD 20
and
WD 21
.
3.
Switch off the machine,
GP 14
.
If the F1 fuse on the IOT PWB has failed. Set the meter to measure ohms. Connect the
black lead to PJ27 pin 9 or pin 10 and the red lead to the bottom of the F1 fuse on the IOT
PWB. If the output is shorted the measurement will be less than 1 ohm.
a.
Disconnect PJ3 on the
IOT PWB.
If the measurement remains below 1 Ohm, this cir-
cuit is good, move to the next step. If the measurement changes to open circuit,
check from PJ3,
Flag 13
, to the
main drive PWB
,
WD 6.
b.
Disconnect PJ4 on the
IOT PWB.
If the measurement remains below 1 Ohm, this cir-
cuit is good, move to the next step. If the measurement changes to open circuit,
check from PJ4,
Flag 16
, to the inverter motor,
PL 10.11 Item 11
, and the duplex
motor, (35-55)
PL 8.22 Item 8
, (65-90 ppm)
PL 8.20 Item 8
,
WD 7.
c.
Disconnect PJ6 on the
IOT PWB.
If the measurement remains below 1 Ohm, this cir-
cuit is good, move to the next step. If the measurement changes to open circuit,
check from PJ6,
Flag 18
, to PJ93 on the
developer module
,
WD 10.
d.
Disconnect PJ10 on the
IOT PWB.
If the measurement remains below 1 Ohm, this
circuit is good, move to the next step. If the measurement changes to open circuit,
check from PJ10,
Flag 20
, to the paper tray bypass,
PL 7.30
,
WD 10.
e.
Disconnect PJ11 on the
IOT PWB.
If the measurement remains below 1 Ohm, this
circuit is good, move to the next step. If the measurement changes to open circuit,
check from PJ11,
Flag 21
, to P/J151 and onto the output device,
WD 5.
f.
Disconnect PJ14 on the
IOT PWB.
If the measurement remains below 1 Ohm, this
circuit is good, move to the next step. If the measurement changes to open circuit,
check from PJ14,
Flag 22
, to PJ55 on the
HVPS
,
PL 1.10
,
WD 11.
g.
Install a new IOT PWB,
PL 1.10 Item 2
.
h.
If after completing the checks above, the F1 fuse on the IOT PWB fails. Switch off
the machine,
GP 14
. Install a new IOT PWB,
PL 1.10 Item 2
.
Disconnect PJ3, PJ4, PJ6, PJ11 and PJ14. Switch off the machine,
GP 14
before a
PJ is connected. Connect each PJ, one at a time until the PJ is found that causes
the fuse to fail. Check and repair the harness or install new components as neces-
sary.
4.
Switch on the machine,
GP 14
.
5.
Disconnect PJ132 on the
power distribution PWB
, check the harness, to DADH,
Flag 8
.
i.
Disconnect PJ135 on the
power distribution PWB
check the harness, to the
CCD
PWB
(W/O
TAG 150
) or
Scanner PWB
(W/
TAG 150
).
