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).

8.
Continue rotating the loader motor worm gear (
1) until the r
otate stub (
3) is positioned as sho
wn.
Notice that the rotator stub (
3) is nearl
y aligned with the cartridge loader tray guide bearing (
2).
9.
Remove the cartridge from the cartridge loader tray.
