5. As the leader pin is secured in the cartridge, the leader pin retention spring clips click into place. If
you do not hear the click, continue rolling until the threader intermediate gear ( 1 in Figure 179)
stops. The LBA is in the correct position.
Note: Be sure to keep tension on the tape as the LBA is drawn into the cartridge.
6. Rotate the loader intermediate gear ( 3 in Figure 179 and 1 in Figure 180) clockwise as viewed
from the front of the drive until it stops. This procedure releases the LBA leader pin.
7. Rotate the threader motor worm gear ( 1 in Figure 180) counterclockwise until the leader block is in
front of the read/write head. This procedure moves the LBA out of the cartridge.
