11J-171 Inserter Paper Sensing and +5V Supply RAP
Use this RAP to find the cause of inserter empty, inserter paper width and +5v supply prob-
lems.
Procedure
Switch off the electricity to the machine, GP 14. Disconnect the power cord from the
customer supply while performing tasks that do not need electricity. Electricity can
cause death or injury. Moving parts can cause injury.
Figure 1 and Figure 2 show the component locations.
If a +5V supply problem is suspected, perform the following:
Go to 11A-171 and check the 0V and +5V supply from the HVF control PWB to the inserter
control PWB. Repair the wiring as necessary, REP 1.2, or refer to 11A-171 HVF BM Power Dis-
tribution RAP.
Install new components as necessary:
•
Inserter control PWB, PL 11.179.
•
HVF control PWB, PL 11.157 Item 2.
To diagnose PPI paper sensing and paper width problems, perform the following:
Enter the dC330 code 11-153, PPI paper present sensor. Actuate the sensor using a sheet of
paper. The sensor display changes.

N
Go to Flag 1 and Flag 2 and check the PPI paper present sensor. Refer to:
•
GP 11 How to Check a Sensor.
•
P/J8 and P/J4 on the inserter control PWB.
•
11A-171 HVF BM Power Distribution RAP
Install new component as necessary:
•
PPI paper present sensor, Q11-153, PL 11.175.
•
Inserter control PWB, PL 11.179.
•
HVF control PWB, PL 11.157 Item 2.
Go to Flag 3 and Flag 4 and measure the voltage from the paper width 1 sensor, while select-
ing width 1 with the sliding paper width guide. The voltage changes.
Y
N
Check the PPI paper width 1 sensor. Refer to:
•
GP 11 How to Check a Sensor.
•
P/J8 and P/J4 on the inserter control PWB.
•
11A-171 HVF BM Power Distribution RAP.
Install new components as necessary:
•
PPI paper width 1 sensor, PL 11.175 Item 13.
•
Inserter control PWB, PL 11.179.
•
HVF control PWB, PL 11.157 Item 2.
Go to Flag 5 and Flag 6 and measure the voltage from the paper width 2 sensor, while select-
ing width 1 with the sliding paper width guide. The voltage changes.
Y
N
Check the PPI paper width 2 sensor. Refer to:
•
GP 11 How to Check a Sensor.
