Signal Processing Problems

Troubles due to signal processing are listed below.
Cause
1) Occurrence of a 04905 SCB2
communication error from the
mechanical control
2) Image forwarding is extremely
slow (i.e., cycle time is exceeded
even for a single reading)
3) Blank white images are gener-
ated (i.e., correction data only)
• For details regarding action in response to other signal-processing errors (10000 to 19999 ; i.e., first digit is
"1".), refer to "4.4.7 SCB2 Error Codes, p.163"

Remedy
1) Confirm whether power is being supplied to the SCB2 (and also carry
out a voltage check).
• If the power-supply cable is connected and 5 V is being supplied, carry out a
check of the power-supply cable and unit, and replace if necessary.
2) Check the connectors between the SCB2 and the MCB2.
3) Confirm whether the CF card is properly inserted.
4) Confirm whether operation is possible when the CF card is replaced.
• If this is possible, replace the original CF card and return it to the plant.
5) Confirm whether operation is possible when the SCB2 is replaced.
• If this is possible, replace the original SCB2 and return it to the plant.
6) Check the simultaneous communication condition of the SCB2,
MCB2, and connection cable
• If simultaneous communication is not being carried out, replace the cable.
Confirm that a 10BASE hub or cables are not being used on the network
system.
1) Confirm that HVSW (SW3) for the ADB2 is on.
2) Confirm whether the high-voltage cable is connected to the ADB2.
3) Confirm that DIP-SW (i.e., the Auto/Manual setting switch for high
voltage) for the ADB2 is set to Auto.
