ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the
individual gears and levers that make up the tape load-
ing/unloading mechanism. Since information about the
state of the mechanism is provided to the System Con-
trol Circuit only through the Mode Switch, it is essential
that the correct relationship between individual gears
and levers be maintained.
All alignments are to be performed with the mecha-
nism in Eject mode, in the sequence given. Each
procedure assumes that all previous procedures have
been completed.
IMPORTANT:
If any one of these alignments is not performed
properly, even if off by only one tooth, the unit will
unload or stop and it may result in damage to the
mechanical or electrical parts.
Alignment points in Eject Position
Alignment 1
Loading Arm, S and T Assembly
Install Loading Arm S and T Assembly so that their
triangle marks point to each other as shown in
Fig. AL2.
Alignment 2
Mode Gear
Keeping the two triangles pointing at each other, in-
stall the Loading Arm T Assembly so that the last
tooth of the gear meets the most inside teeth of
the Mode Gear. See Fig. AL2.
Alignment [a]
Tape Guide Assembly
Measurement of the screw must be as specified in
Fig. AL3.
