7. As the tape leader block assembly (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 in Figure 209) 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 208 on page 274.
8. Notice these mechanisms:
a. Loader mechanism gear ( 6 in Figure 209) nearest the front of the drive that actuates the
cartridge loader mechanism.
b. Position of the rotate stub ( 3 in Figure 209).
c. Front loader motor worm gear ( 1 in Figure 209). Rotating this gear allows the loader
mechanism gear ( 8 in Figure 209) to turn.
9. Rotate the loader motor worm gear ( 1 in Figure 209) to turn the threader mechanism gear ( 6 in
Figure 209) counterclockwise. Continue turning until the rotator stub ( 3 in Figure 209) loses contact
with the lever ( 7 in Figure 209). This action releases the LBA leader pin.
10. Rotate the threader motor worm gear ( 4 in Figure 209) to turn the threader mechanism gear ( 6 in
Figure 209) counterclockwise. This action moves the LBA out of the cartridge and past the
read/write head. Stop this rotation when the LBA is near the tape guide roller nearest the rear of the
