5. Notice the following mechanisms:
a. Loader mechanism gear (8) nearest the front of the drive that actuates the cartridge loader
mechanism
b. Position of the rotator stub (3).
c. Front loader motor worm gear (1). Rotating this gear allows the loader mechanism gear (8) to
turn.
6. Rotate the loader motor worm gear (1) to turn the loader mechanism gear (6) counterclockwise.
Continue turning until the rotator stub (3) loses contact with the lever (7). This action releases the
LBA leader pin.
7. Rotate the threader motor worm gear (4) to turn the threader mechanism gear (6)
counterclockwise. This action moves the LBA out of the cartridge and past the read/write head.
Stop this rotation when the LBA is near the tape guide roller nearest the rear of the drive (1).
