Manually Removing a T ape Cartridge If problem-determination procedures identify the Ultrium 2 T ape Drive as the source of a problem, you can optionally perform one of the following: v Replace the entire unit. For more information, contact your OEM Product Application Engineer (P AE). v Manually remove the cartridge (see “ Removing the Cartridge[...]

T o manually remove a tape cartridge, perform the following steps: 1. Place the drive so that the front faces you, then tilt it on its left side (see Figure 30). 2. Locate the access hole at the bottom of the unit (see 1 in Figure 30). 3. Insert a 2.5-mm allen wrench into the access hole and position the wrench so that it is seated in the scr[...]

6. Continue to rotate the allen wrench until you feel resistance. The tape has been rewound as far as it can go without unthreading. Note: The number of required rotations depends on where the beginning of the tape is on the cartridge ’ s takeup reel. Y ou may have to rotate the allen wrench for a lengthy period. 7. With the allen wrench still in[...]

Fixing an Internal Jam Attention: This procedure must be performed only by trained service personnel. If problem-determination procedures identify the Ultrium 2 T ape Drive as the source of a problem, replace the entire unit. If you are not a trained service person, do not attempt to open the drive for repairs. Attempting a repair other than the ma[...]

4. Examine the drive to determine the cause of the problem: v If the tape is broken, do not attempt repair . Return the drive and the stuck tape to your reseller for maintenance (note that your tape will be scrapped). v If the leader pin dropped from the leader block, go to step 5 on page 90 and continue this procedure. v If the leader block pulled[...]

5. Place the tape drive so that the front faces you, then tilt it on its left side (see Figure 32). 6. At the bottom of the drive, locate the access hole ( 1 in Figure 32). Attention: In the following steps, do not allow drive components to touch the head 2 . Damage may result to the head. 7. Insert a 2.5-mm allen wrench into the access[...]

9. While keeping the tape taut with your fingers, rotate the allen wrench clockwise 1 to wind the excess tape into the cartridge. Guide the leader pin toward the cartridge and drop it inside the cartridge door . Ensure that no tape is left outside of the cartridge. Remove the allen wrench. Note: Do not attempt to seat the leader pin into the [...]

12. Rotate the loader motor gear in the unload direction until the leader block is fully inside the drive (see 1 in Figure 34). Figure 34. Rotating the loader motor gear until the leader block is fully inside the drive. The drive is shown on its side. The head is on the right and the arm of the head brush at the bottom of the figure. 92 IBM T[...]

13. Continue to rotate the loader motor gear counterclockwise. The leader block retracts and occupies the opening to the drive (see 1 in Figure 35). Figure 35. Rotating the loader motor gear so that the leader block retracts. The drive is shown on its side. The head is on the right and the arm of the head brush at the bottom of the figure. Ch[...]

14. Rotate the loader motor gear counterclockwise until you feel resistance and the cartridge rises and ejects (see Figure 36). 15. Remove the tape cartridge. If the leader pin is not seated correctly in the cartridge, see “ Repositioning or Reattaching a Leader Pin ” on page 55. 16. Copy the data on the stuck tape cartridge to another cartridg[...]
