Go to Flag 4. Check for +5V on P/J451 pins 1 to 2 on the CCD PWB right side. The
voltage is good.

Perform the following:
• Check all harness connectors on the scanner PWB and CCD PWB are
securely connected.
• Check the CCD PWB for damaged components. Install new components as
necessary:
– (32-38 ppm Only) CCD PWB, PL 14.25 Item 19.
– (45-55 ppm Only) Scanner, PL 14.20 Item 1.
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/J452 pins 17 to 18 on the scanner PWB. The voltage is
good.

Check the harness between P/J451 and P/J452. If necessary, install a new harness, PL
14.25 Item 23.
Perform REP 14.7A Scan Carriage Home Sensor, to access the sensor, but do not disconnect
the harness from the sensor.
Switch on the machine, GP 14. Enter the dC330 input code 14-100, Figure 1. Use a strip of
paper to actuate the scan carriage home sensor, Q14-100. The display changes.

Go to Flag 1. Check Q14-100. Refer to:
• GP 11 How to Check a Sensor.
• P/J454, 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 14.25 Item 16.
• Scanner PWB, PL 14.25 Item 4.
• Scanner, PL 14.20 Item 1.
Perform ADJ 14.1A Optics Cleaning Procedure.
Re-install Q14-100. 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.

Go to Flag 2. Check the wiring and P/J457. The wiring and connector are good.
Y
N
Repair the wiring and connector, REP 1.2. If necessary, install a new scan motor, PL
14.25 Item 2.
Perform the following:
• Check the scan motor bracket, the rubber component can fail, allowing the motor to
move out of position. If necessary, install a new scan motor bracket, PL 14.25 Item
18.
• If necessary install a new scan motor, PL 14.25 Item 2.
• If necessary install a new scanner, PL 14.25 Item 1.
The sensor and scan motor are working correctly, the fault may be intermittent. Check the fol-
lowing:
• 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, refer to REP
14.11A. If necessary, go to REP 14.11A Scan Motor and re-position the scan motor so
that the belt does not slip.
• Check the scan motor bracket, the rubber component can fail, allowing the motor to move
out of position. If necessary, install a new scan motor bracket, PL 14.25 Item 18.
