5. As the leader pin is secured in the cartridge, you should hear the leader pin
retention spring clips click into place. If you do not hear the click, continue
rolling until the threader intermediate gear (

in Figure E-12) 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 (

from the front of the drive until it stops. This releases the LBA leader pin.
7. Rotate the threader motor worm gear (

in Figure E-13) counterclockwise
until the leader block is in front of the Read/Write head. This moves the LBA
out of the cartridge.
