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 A-22) 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 ( in Figure A-22 and in Figure A-23)
clockwise as viewed from the front of the drive until it stops. This releases the
LBA leader pin.
7. Rotate the threader motor worm gear ( in Figure A-23) counterclockwise until
the leader block is in front of the Read/Write head. This moves the LBA out of
the cartridge.
