Status Indicator RAPs
14-110B Scan Carriage Home Sensor RAP (W/TAG 150)
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14
. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
•
Make sure that the correct RAP is used. To identify the correct RAP to use, go to the
14-
110
Scan Carriage Home Sensor Entry RAP.
•
Check that the scan cables are correctly positioned,
Figure 2
.
•
Check that the harness from PJ152 is not routed under the single board controller PWB. If
the harness was under the PWB, examine the harness sleeving for punctures or other
damage. If necessary, install a new DADH/power distribution PWB harness,
PL 3.24 Item
6
. Route the new harness to the right, away from the single board controller PWB. If this
has caused a blown fuse F1 on the power distribution PWB, install a new power distribu-
tion PWB,
PL 3.24 Item 5
.
NOTE: This fault has been caused on a number of machines by bad routing of the DADH/
power distribution PWB harness
PL 3.24 Item 6
.
Procedure
Go to
Flag 3
. Check for +24V on
P/J135
between pins 1 to 3 and 2 to 4 on the power distribu-
tion PWB. The voltage is good.

As necessary, perform the steps that follow:
•
Go to the
01G
+24V Distribution RAP.
•
Go to the
01B
0V Distribution RAP, refer to the 24V return.
Go to
Flag 3
. Check for +12V on
P/J135
between pins 6 to 8 on the power distribution PWB.
The voltage is good.
Y
N
As necessary, perform the steps that follow:
•
Go to
01F
+12V Distribution RAP.
•
Go to
01B
0V Distribution RAP, refer to the 12V return.
Check that +24V is available in the scanner by entering the
dC330
output code 14-005. The
exposure lamp illuminates.
Y
N
Go to
Flag 3
. Check for +24V on
P/J920
between pins 1 to 2 and 3 to 4 on the scanner
PWB. Also check for +12V on
P/J920
between pins 1 and 2 on the scanner PWB. The
voltages are good.
Y
N
Check the harnesses between the power distribution PWB and the scanner PWB. If
necessary, install a new single board controller PWB/DADH comms/scanner power
harness
PL 14.15 Item 5
.
Go to the
14D
Exposure Lamp Failure RAP.
Check that +5V is available in the scanner by entering the
dC330
input code 14-310, actuate
the input module angle sensor by opening and closing the DADH. The display changes.
Y
N
Go to
Flag 4
. Check for +5V on
P/J136
between pins 1 to 4 on the PDB PWB. Also check
for +3.3V on
P/J136
between pins 2 and 3 on the PDB PWB. The voltages are good.
Y
N
lnstall new components as necessary:
•
PDB PWB,
PL 3.24 Item 5
.
Go to the
14A
Scanning Document Size RAP and check the input module angle sensor,
Q14-310.
Go to
Flag 4
. Check for +5V on
P/J920
between pins 7 to 8 on the scanner PWB. Also check
for +3.3V on
P/J920
between pins 15 and 16 on the scanner PWB. The voltages are good.
Y
N
Check the harness between
P/J136
and
P/J920
. If necessary, install a new SBC PWB/
DADH comms/scanner power harness,
PL 14.15 Item 5
.
Enter
dC330
code 14-100 to check the scan carriage home sensor, Q14-100. Activate Q14-
100. The display changes.
Y
N
Check Q14-100. Refer to:
•
GP 11
How to Check a Sensor.
•
P/J924
,
Scanner PWB
.
•
01D
+3.3V Distribution RAP.
•
01B
0V Distribution RAP, refer to the 3.3V and 5V return.
Repair or install new components as necessary:
•
Sensor harness,
REP 1.2
.
•
Scan carriage home sensor,
PL 14.15 Item 16
.
•
Scanner PWB,
PL 14.15 Item 4
.
•
Scanner,
PL 14.10 Item 1
.
Perform
ADJ 14.2
Optics Cleaning Procedure.
Switch off the machine,
GP 14
. Open the DADH or document cover. Switch on the machine,
GP 14
. Observe the scan carriage as the machine initializes. The scan carriage moves
away from and back to the scan carriage home sensor.
Y
N
Go to
Flag 2
. Check the wiring and
P/J929
. The wiring and connector are good.
Y
N
Repair the wiring and connector,
REP 1.2
.
Perform the following:
•
If necessary install a new scan motor,
PL 14.15 Item 2
.
•
If necessary install a new scanner,
PL 14.10 Item 1
.
The sensor and carriage motor are working correctly, the fault may be intermittent. Check the
following:
•
The connectors are fully seated and the wiring is not damaged.
•
Q14-100 is mounted correctly.
•
Check that the scanner drive belt is not loose, causing the belt to slip. If necessary re-
position the scan motor so that the belt does not slip.
