2. Begin spooling the tape back into the cartridge by turning the supply reel motor (▌4▐ in Figure 178)
clockwise.
3. Continue spooling 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. Continue spooling until all tape is removed
from the takeup reel (▌3▐ in Figure 178).
4. Locate the threader intermediate gear (▌1▐ in Figure 179 on page 185) near the rear of the drive. You
can use your finger to rotate the threader intermediate gear (▌1▐ in Figure 179 on page 185) and
slowly rotate the threader mechanism gear (▌2▐ in Figure 179 on page 185) clockwise. This procedure
draws the tape leader block assembly (LBA) into the cartridge.
