ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align theAlignment 1
individual gears and levers that make up the tape

loading/unloading mechanism. Since information
about the state of the mechanism is provided to theInstall Loading Arm S and T Assembly so that their

individual gears and levers be maintained.
Alignment 2
All alignments are to be performed with the mech-
anism in Eject mode, in the sequence given. Each
Mode Gear
procedure assumes that all previous procedures have
been completed. 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.
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
