9. Rotate the threader motor worm gear 4 to turn the threader mechanism gear 6 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 drive rear end (see 1 in Figure 72 on page 201).
10. See Figure 71 on page 200. Continue rotating the loader motor worm gear 1 until the rotator stub 3
is positioned. Notice that the rotator stub 3 is nearly aligned with the cartridge loader tray guide
bearing 2 .
11. Remove the cartridge from the cartridge loader tray.
12. Reassemble the drive by reversing Step 5 in “Manual cartridge removal” on page 195
13. Reassemble the drive canister by reversing Step 2 in “Manual cartridge removal” on page 195.
14. Install a new drive canister. See “Replacing or reinstalling the drive canister” on page 254.
15. Repack and return the failed drive through your IBM parts network. For information about
repackaging the failed drive canister, see “Repacking instructions” on page 181.
No apparent failure or damage to tape
Use this procedure if you cannot see a failure or there does not seem to be any damage to the tape. Use
Figure 71 on page 200, as you follow this procedure.
1. Set the drive on its left side with the head and the tape path facing up.
2. See Figure 70 on page 199. From the bottom of the drive, locate the access hole
1 in the bottom
cover. Insert a 2.5 mm offset hex wrench through the bottom cover access hole and into the reel
motor axle. Begin spooling tape back into the cartridge by turning the hex wrench clockwise.
3. Continue spooling tape into the cartridge until the tape is taut and remains within the flanges of the
tape guiding rollers. Ensure that you do not stretch the tape.
4. See Figure 71 on page 200. Locate the threader motor worm gear 4 on the rear end of the drive. Use
your finger to rotate the threader motor worm gear and slowly drive the threader mechanism gear 6 .
Rotating the threader motor worm gear clockwise draws the leader block assembly (LBA) into the
cartridge.
5. 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.
6. Notice the following -
• Loader mechanism gear 8 nearest the front of the drive that actuates the cartridge loader
mechanism
• Position of the rotator stub 3
• Front loader motor worm gear 1 . Rotating this gear allows the loader mechanism gear 8 to turn.
7. Rotate the loader motor worm gear 1 to turn the loader mechanism gear 8 counterclockwise.
Continue turning until the rotator stub 3 passes under the aluminum bracket 7 . This action releases
the LBA leader pin.
8. Rotate the threader motor worm gear 4 to turn the threader mechanism gear 6 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 drive rear end (see 1 in Figure 72 on page 201).
9. See Figure 71 on page 200. Continue rotating the loader motor worm gear 1 until the rotator stub 3
is positioned. Notice that the rotator stub 3 is nearly aligned with the cartridge loader tray guide
bearing 2 .
10. Remove the cartridge from the cartridge loader tray.
11. Reassemble the drive by reversing Step 5 in “Manual cartridge removal” on page 195
12. Reassemble the drive canister by reversing Step 2 in “Manual cartridge removal” on page 195.
13. Install a new drive canister. See “Replacing or reinstalling the drive canister” on page 254.
14. Repack and return the failed drive through your IBM parts network. For information about
repackaging the failed drive canister, see “Repacking instructions” on page 181.
