Tape Pulled from or Broken near Leader Pin
Figure A-17. Drive with cover removed to reveal gear train
1. Pull out tape from the takeup reel.
Note: If there is more than approximately 0.6 m (2 ft.) of tape on the takeup reel,
go to “Tape Broken in Mid-tape” on page A-16.
2. If there is less than approximately 0.6 m (2 ft.) of tape on the takeup reel, cut off
the excess tape as close to the leader pin, as possible.
3. Reattach the leader pin to the remaining tape.
4. Locate the threader intermediate gear ( in Figure A-17) near the rear of the
drive. You can use your finger to rotate the threader intermediate gear ( in
Figure A-17) and slowly rotate the threader mechanism gear (
in Figure A-17)
clockwise. This draws the tape leader block assembly (LBA) into the cartridge.
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-17) 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 motor worm gear ( in Figure A-17 and in Figure A-18)
clockwise as viewed from the front of the drive until it stops. This releases the
LBA leader pin.
7. Rotate the threader intermediate gear ( in Figure A-17) counterclockwise until
the leader block is in front of the Read/Write head. This moves the LBA out of
the cartridge.
