Procedure
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 "Half height
drive: Tape broken in mid-tape" on page 234
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 ( 1 ) near the rear of the drive. You can use your finger to rotate
the threader intermediate gear ( 1 ) and slowly rotate the threader mechanism gear ( 2 ) clockwise.
This action draws the tape leader block assembly (LBA) into the cartridge.
5. As the leader pin is secured in the cartridge, you hear the leader pin retention spring clips click into
place. If you do not hear the click, continue rolling until the threader intermediate gear ( 1 ) stops. The
LBA is in the correct position.
6. Rotate the loader motor worm gear ( 3 ) clockwise as viewed from the front of the drive until it stops.
This action releases the LBA leader pin.
7. Rotate the threader intermediate gear ( 1 ) counterclockwise until the leader block is in front of the
read/write head. This action moves the LBA out of the cartridge.
