5607 TU/SUP REEL STOPPED DUE TO A CUT TAPE
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Tape is cut due to abnormal tension
or a mechanism defect or because
the cassette was inserted while the
tape was slack.
•Detection method : When the FGs from the SUP and
TU reels were not detected at all (at
pins 59 and 60 of IC401) during load-
ing.
5702 TAPE END DETECTED AFTER SHORT REW
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Tape is cut after the end of the tape
has been detected. The mode tran-
sition of the mechanism failed.
•Detection method : When the tape end sensor output
(at pin 125 of IC401) remains Low
even after 3 seconds have elapsed
since the start of the short REW
operation following the tape end
detection in play mode, etc.
5802 TAPE BEGIN DETECTED AFTER SHORT FF
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Tape is cut after the end of the tape
has been detected. The mode tran-
sition of the mechanism failed.
•Detection method : When the tape begin sensor output
(at pin 126 of IC401) remains Low
even after 3 seconds have elapsed
since the start of the short FF op-
eration following the tape beginning
detection in the reverse search
mode, etc.
7001 DRUM MOTOR ROTATION ERROR
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Malfunction of the drum motor,
MDA circuit or FG detector circuit.
•Detection method : When the drum FG has not been
detected (at pin 54 of IC401) for
more than 4 seconds in the drum
driving mode.
7101 CAPSTAN MOTOR ROTATION ERROR
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Malfunction of the capstan motor,
MDA circuit or FG detector circuit.
•Detection method : When the drum FG has not been
detected (at pin 55 of IC401) for
more than 2 seconds in the capstan
driving mode.
3300 UNLOADING INCOMPLETE
•VCR operation : After the first unloading error, the
cassette is loaded temporarily, then
unloading is retried. If the retry fails
again, the AUTO OFF mode is initi-
ated.
•Cause : Malfunction of the loading motor,
rotary encoder or mechanism.
•Detection method : The rotary encoder output is
checked (at pins 44, 45 and 46 of
IC401) and an error is detected
when unloading has not completed
in 4 seconds.
4000 INTAKE INCOMPLETE
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Malfunction of the cassette hous-
ing switch or cassette housing mo-
tor.
•Detection method : When completion of insertion is not
detected (at pin 27 of IC401) within
3 seconds after the start.
4100 EJECTION INCOMPLETE
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Malfunction of the cassette hous-
ing switch or cassette housing mo-
tor.
•Detection method : When completion of ejection is not
detected (at pin 27 of IC401) within
3 seconds after the start.
5605 TAPE BEGIN/END DETECTED SIMULTANEOUSLY
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Tape is cut due to abnormal tension
or a mechanism defect or because
the cassette was inserted while the
tape was slack.
•Detection method : When both the tape begin sensor
(at pin 126 of IC401) and the tape
end sensor (at pin 125 of IC401)
output Low level together when a
cassette is loaded.
5606 SP REEL RUNAWAY DURING UNLOADING
•VCR operation : The AUTO OFF mode is initiated.
•Cause : Tape is cut due to abnormal tension
or a mechanism defect or because
the cassette was inserted while the
tape was slack.
•Detection method : When the detected TU reel rotation
count (at pin 59 of IC401) exceeds
30 revs. per sec. (1200 pulses) dur-
ing unloading.
