▌1▐ Loader motor worm gear ▌2▐ Leader block assembly (LBA)
8. Rotate the loader motor worm gear (▌3▐ in Figure 174 on page 180) counterclockwise as viewed from
the front of the drive until it stops.
9. Remove the cartridge from the cartridge loader tray.
10. Reassemble the drive, reversing the steps in “Beginning procedure” on page 177.
11. Reassemble the library chassis. See “Ending procedure” on page 186.
Tape broken in mid-tape
1. With the front of the drive facing you, pull an arm's length of tape out of the takeup reel. From the
takeup reel, thread tape around the rear of the tape path and over the head rollers on the left side of
the drive.
Note: If there is less than approximately 5 cm (2 in.) of tape on the takeup reel, go to “Tape pulled
from or broken near leader pin” on page 180.
2. From the supply reel inside the cartridge, pull approximately 0.3 m (1 ft.) of tape.
3. Make sure that the tape is not twisted. Untwist tape if required.
4. Moisten a cotton swab with water, and wet approximately 13 mm (0.5 in.) of the tape end. Overlap
the tape ends, loosely mending them together.
5. Set the drive on its left side with the head and tape path facing up.
6. Turn the supply reel (▌4▐ in Figure 176 on page 182) clockwise, carefully guiding the mended portion
of the tape to wind around the hub of the supply reel that is located inside the cartridge. Continue
spooling into the cartridge until the tape is taut. The tape must remain within the flanges of the tape
guiding rollers. Turn the supply reel (▌4▐ in Figure 176 on page 182) 10 more turns. Ensure that you
do not stretch the tape.
