Initial issue
15-381 CCD AGC
Automatic Gain Control (AGC) for CCD Channel 2 red failed.
Initial Actions
• Verify that the Platen Glass is installed correctly (REP 6.2).
• Verify that NVM location 715-400 = 1
Procedure
Enter dC330 [6-002] and press Start. The Exposure Lamp illuminates.
YN
Go to the 6-371.
The Exposure Lamp illumination is bright and steady.
YN
Go to P/J722 (Figure 2) and P/J724 (Figure 1) and check the wires for an open or short
circuit.
Verify that P/J742 on the Lamp Ballast PWB and P/J724 on the IIT/IPS PWB are seated.
If the wires and connectors are good, replace the Exposure Lamp (PL 18.6).
If the problem continues, replace the Lamp Ballast PWB (PL 18.6).
If the problem continues, replace the IIT/IPS PWB (PL 18.3).
Remove the Platen Glass (REP 6.2). The white reference strip on frame under the Regis-
tration Gate is clean and undamaged.
YN
Clean the white reference strip.
Go to P/J721 (Figure 3) and check the flat cable on the IIT/IPS PWB and P/J741 on the CCD
PWB for damage. Reseat the flat cable.
If the problem continues, replace the Lens Kit (PL 18.4).
If the problem continues, replace the IIT/IPS PWB (PL 18.3).
