14C Scanning Document Size RAP (65-87 ppm)

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.
Figure 1 shows the component location. Go to Flag 1 and check the voltages at P/J135 on the
power distribution PWB. As necessary, refer to:
• 01D +3.3V Distribution RAP.
• 01G +24V Distribution RAP.
• 01B 0V Distribution RAP.
Check the wiring between P/J135 on the power distribution PWB in the image processing mod-
ule and P/J455 and P/J450 on the scanner PWB. Repair as necessary, REP 1.2 or install a
new power distribution PWB/scanner PWB harness, PL 14.16 Item 7.
Check that the input module angle sensor actuator is not damaged, if necessary, install a new
actuator, PL 14.15 Item 10.
NOTE: The +5V supply for the sensors is generated from the +24V supply on the scanner
PWB, see Figure 2. If necessary, install a new scanner PWB, PL 14.16 Item 8.
Enter the dC330 input code 14-310, Document Handler Angle Sensor and actuate the input
module angle sensor, Q14-310 by opening and closing the DADH. The display changes.

Go to Flag 2 and check the input module angle sensor, Q14-310. Refer to GP 11, How to
Check a Sensor.
Repair or install new components as necessary:
• Input module angle sensor, PL 14.15 Item 7.
• Scanner PWB, PL 14.16 Item 8.
Raise the DADH, enter the dC330 input code 14-315, actuate the document size sensor 1,
Q14-315 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, Q14-320. The
display changes for both sensors.
Y N
Go to Flag 3, 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.
Repair or install new components as necessary:
• Document size sensor, PL 14.16 Item 11.
• Scanner PWB, PL 14.16 Item 8.
The scanner is working correctly, perform dC604 Registration Setup.
