B220 - Gripper could not get cartridge from magazine

Edit online

The gripper on the robotic accessor failed to grab a cartridge from the service magazine. This could be caused by the robotic accessor mispositioned when trying grab from a service magazine, a faulty gripper or a faulty magazine. This fix procedure describes how to diagnose and correct the issue.

Fix procedure

  1. Open the rear door.
  2. If the power LED on the service magazine is OFF, disconnect the Service Magazine from the bay and then reinsert it.
  3. If the power LED is now ON, the problem is resolved, close the rear door and go to Gripper Verification. Otherwise, contact IBM support to request magazine replacement.
  4. Remove the magazine and ensure the cartridges can be manually removed and properly inserted in the magazine slot.
  5. If the affected cartridge can be manually removed and inserted in the slot, reinsert the magazine, close the rear door and go to Gripper Verification.
  6. If the cartridge is damaged reinsert the magazine (without the damaged cartridge), close the rear door and contact your media supplier.
  7. If the cartridge is not damaged and there’s still problems inserting or removing cartridges manually in the slot, close the rear door and go to Contact IBM support to request magazine replacement.
    Additional Troubleshooting:

    The cartridge is in the gripper

    1. Refer to the video: Removing stuck cartridge from the gripper.
    2. Once you have removed the cartridge, check and remove any debris in the Y-rail gear rack such as a piece of plastic.
    3. Check and remove any other debris which would interfere with accessor motion.
    4. Verify the Y end stop is not damaged (end stop bent). If damaged Contact IBM support.
    5. Otherwise, go to Gripper verification.
Gripper verification
  1. If the front LED lighting is not solid yellow, put the library in service mode:
    1. From the management GUI., go to Actions > Change Library State.
    2. Choose In Service Mode (Offline) option and then click the Set button.
  2. Open the front door.
  3. Manually move the grippers pickers and confirm no part is damaged and it moves freely. This can be done by moving the motor pulley (See  3  in Figure 1) with your fingers. Pay attention to the gripper fingers to ensure they are not damaged.
  4. Ensure that the gripper motor cable connector and cartridge present sensor cable connectors are firmly seated at the GCC card and no damage to cables is visible. Referring to Figure 1,  1  is the connection for the top gripper and  2  is the connection for the bottom gripper.
  5. Close door.
  6. Set the library online:
    1. From the management GUI., go to Actions > Change Library State.
    2. Choose Online option and then click the Set button.
