REGIUS MODEL 190 Service Manual Ver.1.00 2004.11.01
4.1.3 Signal Processing Problems
Troubles due to signal processing are listed below.
• For details regarding action in response to other signal-processing errors (10000 to 19999 ; i.e., fi rst digit is
"1".), refer to " 4.4.7 SCB2 Error Codes, p.163"
Cause Remedy
1) Occurrence of a 04905 SCB2
communication error from the
mechanical control
1) Con fi rm 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) Con fi rm whether the CF card is properly inserted.
4) Con fi rm 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) Con fi rm 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.
2) Image forwarding is extremely
slow (i.e., cycle time is exceeded
even for a single reading)
Con fi rm that a 10BASE hub or cables are not being used on the network
system.
3) Blank white images are gener-
ated (i.e., correction data only)
1) Con fi rm that HVSW (SW3) for the ADB2 is on.
2) Con fi rm whether the high-voltage cable is connected to the ADB2.
3) Con fi rm that DIP-SW (i.e., the Auto/Manual setting switch for high
voltage) for the ADB2 is set to Auto.
