ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the
individual gears and levers that make up the tape
loading/unloading mechanism. Since information
about the state of the mechanism is provided to the
System Control 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 mech-
anism 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,
install 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.
