released.
Er32-000 Tape end could not be
released.
Er33-000
Reel position sensor
detected STANDARD and
MINI at the same time.
Note 1: For errors of the servo system and tape path system, basic operations can be checked in the test mode.
Note 2: The "Possible Cause" above are only for the main problem area.
Note 3: Regarding the test mode, refer to section "2-25. Menu (LCD)."

Error detection method
The mechanism control
MICRO COM. could not
obtain an appropriate input
signal from the cam
position sensor or detected
abnormal current of the
function cam (LD) motor.
The mechanism control
MICRO COM. could not
obtain an appropriate input
signal from the reel position
sensor or detected
abnormal current of the reel
position motor.
The detection signal
(detected tape top or tape
end after SHORT FF or
SHORT REW) was input to
the mechanism control
MICRO COM. from the tape
top sensor or tape end
sensor.
Both the detections signals
from the L reel position
sensor and S reel position
sensor were input to the
mechanism control MICRO
COM..
