Initial Actions
Make sure that the correct RAP is used. To identify the correct RAP to use, go to the 14A
Scanning Document Size Entry RAP
Procedure
WARNING
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.
Check that the input module angle sensor actuator is not damaged, if necessary, install a new
input module angle sensor actuator, PL 14.25 Item 21.
Enter the dC330 input code 14-310. Actuate the input module angle sensor, Q14-310 by open-
ing and closing the DADH. The display changes.

Go to the following RAPs:
•
01B 0V distribution RAP, refer to the 12V return.
•
01F +12V Distribution RAP.
Go to Flag 4. +5V is available at pin 3 on Q14-310 connector (brown wire).

Remove the CVT glass and document glass, REP 14.6A.
Remove the PWB cover, 3 screws, PL 14.25 Item 1.
Re-install the scanner top cover and GUI, but do not install the screws. Re-connect
the power cord and switch on the machine, GP 14.
Go to Flag 2. Check for +12V on P/J450 between pins 1 and 2 on the CCD PWB.
The voltage is good.

Check the harness between P/J135 and P/J450 for an open or short circuit.
Repair the wiring, REP 1.2, or install a new harness, PL 14.25 Item 13.
Go to Flag 3. Check for +5V on P/J451 between pins 1 and 2 on the scanner PWB.
The voltage is good.

Input module angle sensor, PL 14.25 Item 16.
•
Scanner PWB, PL 14.25 Item 4.
•
Scanner, PL 14.20 Item 1.
Raise the DADH. Enter the dC330 input code 14-315. Actuate the document size sensor 1 by
placing a piece of paper on the document glass above the sensor, Figure 1. Enter the dC330
input code 14-320 and repeat the test for document size sensor 2. The display changes for
both sensors.

Go to Flag 1. Check the document size sensors 1 and 2, refer to:
•
GP 11 How to Check a Sensor.
NOTE: If necessary, temporarily install the document glass when checking the size
sensors, to ensure that the document is the correct distance from the sensor.
•
01D +3.3V Distribution RAP.
•
01B 0V Distribution RAP, refer to the 3.3V return.
Repair or install new components as necessary:
•
