Procedure
1. From the left side of the drive, pull out tape from the take up reel.
Note: If there is more than approximately 0.6 m (2 ft.) of tape on the take up reel, go to "Full height
drive: Tape broken in mid-tape" on page 250.
2. If there is less than approximately 0.6 m (2 ft.) of tape on the take up reel, cut off the excess tape as
close to the leader pin, as possible.
3. Locate the threader motor worm gear ( 4 ) the rear of the drive. Use your finger to rotate the threader
motor worm gear and slowly rotate the threader mechanism gear ( 6 ) clockwise. This action rotates
the threader motor worm gear ( 4 ) clockwise, drawing the tape leader block assembly (LBA) into the
cartridge.
4. As the LBA is secured in the cartridge, you hear the LBA retention spring clips click into place. If you
do not hear the click, continue rolling until the threader motor worm gear ( 4 ) 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 by using a hex
wrench as shown in Figure 114 on page 245.
