Tape Broken in Midtape
Note: The term ‘midtape’ refers to tape that was not in the first or final 1.8 m (6 ft) of
tape.
Use this procedure if the tape is broken in midtape, and not near either end.
1. With the front of the drive facing you, pull 0.6 m (2 ft) of tape out of the drive,
from the take-up reel on the left side of the drive.
Note: If there is less than approximately 5 cm (2 in.) of tape on the take-up reel,
go to “Tape Pulled from Leader Pin or Broken Near Leader Pin” on
page 9-49.
2. From the supply reel inside the cartridge, pull approximately 0.3 m (1 ft) of tape.
3. From the take-up reel, thread tape around the rear of the tape path and over the
head rollers on the left side of the drive.
4. Using a cotton swab moistened with water, 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 the tape path facing up.
6. From the bottom of the drive, locate the access hole ( in Figure 9-53) 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.
