ERROR-08 DRUM ERROR
Description:
Malfunction of drum motor was detected.
Detecting condition:
When the drum FG cycle is shifted more than about
±
20 % continuously for
more than 10 seconds as compared with during normal rotation.
Sub error message:
None
Possible causes:
.
Drum motor trouble
.
SV CPU (IC801 on SS-95 board) trouble
.
DR MPU (IC100 on DR-508 board) trouble
.
Drum motor drive circuit (Q302 on DR-508 board) trouble
.
Drum FG/PG waveform shaper circuit (IC303 on DR-508 board) trouble
.
Assembly defect during upper drum replacement
Protecting operation:
Stops the tape transport and switches to the rest state in the unthread end state.
ERROR-09 THREAD TIME OVER
Description:
Malfunction of threading or unthreading operation was detected.
Detecting conditions:
1) When no operation is completed within about six seconds after operation
start.
2) When states other than unthread end are continued for more than six seconds
in case that the unit should be in the unthread end state.
Sub error message:
None
Possible causes:
.
Unthread end sensor (TR-120 board) trouble
.
Thread end sensor (TR-120 board) trouble
.
Thread end/unthread end input port (IC801 on SS-95 board) trouble
.
Threading motor trouble
.
Threading FG sensor (PTC-102 board) trouble
.
Threading FG waveform shaper circuit (IC207 on DR-508 board) trouble
.
Threading motor drive circuit (IC500 on DR-508 board) trouble
.
Threading mechanism trouble
Protecting operations:
Ejects the cassette during cassette insertion or ejection.
Switches to the protection mode during tape threading/unthreading.
Stops the tape transport and switches to the rest state in cases except the above.
