5. Inspect the drive to decide which of the following conditions most closely match the symptom on the drive:
Tape spooled off the supply reel - All the tape appears to be on the takeup reel and no tape is on the supply reel (inside the cartridge). Test the drive after the
procedure is completed.
Tape pulled from leader pin (or broken at the front end) - All the tape appears to be on the supply reel (inside the cartridge) and little or no tape appears to be
on the takeup reel. The leader block is positioned in the takeup reel. Return the drive after the procedure is completed.
Tape broken in mid-tape - Tape appears to be on both the supply reel (inside the cartridge) and takeup reel. Test the drive after the procedure is completed.
Tape tangled along tape path - Tape appears to be tangled and damaged but intact. Return the drive after the procedure is completed.
-- OR --
No damage to tape (or no apparent failure) - There appears to be no damage or slack to the tape. Return the drive after the procedure is completed.

Attention: DO NOT TOUCH THE OUTER GUIDE RAIL (2 in Figure 1). THIS RAIL IS VERY DELICATE AND EASILY DAMAGED.
1. From the takeup reel, pull an arm 's length of tape around the rear of the tape path and over the head and rollers on the left side of the drive.
2. Set the drive on its left side with the head and tape path facing up.
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 and feed it onto the supply reel (inside the cartridge).
5. Turn the supply reel (4 in Figure 1) clockwise, allowing the moistened tape to adhere to the hub as it winds around the supply reel (inside the cartridge).
