Figure 120. Rewinding tape into cartridge

Loader motor worm gear

Takeup reel motor

Outer guide rail (WARNING: Do

Not Touch)

Supply reel motor

2. Begin spooling the tape back into the cartridge by turning the supply reel motor (

) 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 (

4. Locate the threader intermediate gear (

) near the rear of the drive. You can use your finger to rotate

the threader intermediate gear (

) and slowly rotate the threader mechanism gear (

) clockwise.

This action draws the tape leader block assembly (LBA) into the cartridge.
