• Transfer the control program dump to the host and print it. Refer to the NCP, SSP, and
EP Diagnosis Guide.
• Resume operations and perform problem determination procedures. If the problem
occurs repeatedly:
Check and, if

and give reference code.
2. If it is a low or medium speed TSS, check whether the LlC or its lines have just been
installed or modified.
• If yes: Verify if the NCP and CDF are matching the LlC configuration. (For a L1CS or
a L1C6 check the configuration sheet values with a PKD.)
If no, correct them. Reload the scanner if other lines are down. Restart the
lines.
If yes, replace the L1C (refer to the 3745 Connection and Integration Guide) and if
the problem persists,

• If no: verify if any other lines driven by this scanner are down.
If no, replace the L1C.
Refer to the 3745 Connection and Integration Guide.
If yes and all the down lines are on the same L1C, the.n re.pJace the L1C.
