General Troubleshooting

SYMPTOM

CORRECTIVE ACTION

Profile memory not storing profiles.

Check battery back up connection to
CN5 of PCB RD200c.

Land pattern on PCB appears
skewed or crooked on video display.

Perform Board to Optics Alignment.
(See page 37)

Reflow head is not parallel with PCB

Perform Reflow Head Planarity
Alignment.  (See page 41)

Lamps in the optical housing
assembly are not operational.

1.  Replace failed lamp or lamps.
2.  Check transistors T1 (PCB side)

and T2 (BGA side), or Micro-
switch S1 located on the chassis.

The camera does not operate.

Check the wiring and connection of
the camera.  If nothing is found
abnormal, replace the camera.
