6. 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 127 on page 216) 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 126 on page 215.
7. Notice these mechanisms:
a) Loader mechanism gear (6 in Figure 127 on page 216) nearest the front of the drive that actuates
the cartridge loader mechanism.
b) Position of the rotate stub (3 in Fig
ure 127 on page 216
).
c)
Front loader motor worm gear (
1 in Fig
ure 127 on page 216
). Rotating this gear allows the loader
mechanism g
ear (
8 in Fig
ure 127 on page 216
) to turn.
8.
Rotate the loader motor worm gear (
1 in Fig
ure 127 on page 216
) to turn the loader mechanism gear
(6 in Fig
ure 127 on page 216
) counterclockwise. Continue turning until the rotator stub (3 in Fig
ure
127 on page 216) loses contact with the lever (7 in Fig
ure 127 on page 216
). This action releases
the LBA leader pin.
9.
Rotate the threader motor worm gear (
4 in Fig
ure 127 on page 216
) to turn the threader mechanism
g
ear (
6 in Fig
ure 127 on page 216
) counterclockwise. This action moves the LBA out of the cartridge
and pas
t the read/write head. Stop this rotation when the LBA is near the tape guide roller nearest
the rear of the drive that is shown as
1 Fig
ure 128 on page 217
.
