Summary: |MEDIA LEADER |DRIVE LEADER |TAPE BUCKLER |

Field Text:
During the load operation the tape leaders failed to buckle. Cartridge must be unloaded before any load recovery action can be attempted. Once the cartridge is extracted from the drive, the drive will automatically recover its buckler position. User should inspect the condition of the cartridge tape leader for integrity before attempting to re-load.

Solution

T1000A/B/C/D Have the customer eject these volsers and check them to verify that the leader is in the proper position and verify that the leader loop in the cartridge is not split.

Description: The 5802 "misbuckle" happens when the buckler is "buckling" (moving toward the rear of the drive) attempting to buckle the leaders.

If the leaders don't buckle, the takeup leader follows the hook as it travels rearward and stays on the hook. At that point, the elevator raises to allow the cart to be removed. Then a misbuckle recovery is needed (remove the cart and an unload is commanded) where servo lowers the elevator and returns the buckler to the home (forward) position, relying on the buckler spring tension. If the leader is pulled into the drive it can hang up on some internal feature and appear to succeed unslacking -- then the buckling attempt is made and it can result in a 5802. OR the cart leader loop (where we buckle) can be split and the takeup leader can slip through, leading to a 5802.
