PRECAUTIONS IN-REASSEMBLING
MOUNTING THE CASSETTE CONTROLLER
Initial setting is indispensable
before placing the cassette controller in the mechanism. The initial
setting
is made in two ways; electrical and mechanical.
Electrical setting:
(1) Make a short-circuit between
TP5001
and TP5002
of the
TP
plug
(TPSOO*)
which is on the
timer
PWB.
(2) Plug in the AC
power
cord and make sure the mechanism is in the initial setting position
(*l)
.
(3) Unplug the
AC
power cord. Remove the above short-circuit.
NOTE: This method is used when the mechanism has been already set on its-PWB.

Mechanical setting:
Turn the loading motor’s
pulley feed gear using a
screwdriver
and be sure
that the mechanism is
back to its initial setting
position
(*l).
Now place
Drive
angle
of
the cassette controller in
cassette control
position. (This method is
applicable for the
mechanism alone.)

COUPLING
TH.E.MECHANISM
TO THE PWB
Match the mechanism’s projections with the two
symbots
(r&nd
reference and oval sub-reference) on the
main PWB. Place the mechanism straight-down in position with due care so that the mechanism chassis’s outer
edges should not damage any parts nearby.
Tighten up the two screws (one for fixing the mechanism and
th6
head amplifier shield, the other on the main
PWB’s
soldering side and located near the loading motor) to fix the mechanism and main PWB. Reconnect the
FFC
cables
(AG,
AD and ZA) and harnesses (AE and AL) between the mechanism and main PWB.
Parts to pay attention to:
Stat-t and end sensors
07
10, D709
Record tip switch
5701
Take special care of the MC-AC connector
(board to board) between the mechanism
and main PWB.
