Removing or replacing a spooling mechanism

Occasionally, only the robotic spooling cable must be removed and replaced. See "Identifying a failed
component" on page 73.
1. Power down the library.
Important: Under normal circumstances, when the library is powered off by using the front Power,
the robot automatically parks and locks into the Base Module behind the Operator Panel. If you are
given a choice during the power down procedure, choose the default park position. To protect the
spooling cable or other sensitive parts, the accessor must be in the Base Module before any
components are removed from the library. If it is not, follow the procedure for returning the accessor
to the base module. See "Returning the accessor to the Base Module" on page 127.
2. Refer to "Preparing to remove the accessor and spooling mechanism from the Base Module" on page
120 for the steps in preparing your library.
3. Remove the left magazine to provide clear access to the spooling mechanism.
4. Follow the steps in "Removing the accessor and spooling mechanism from the Base Module" on page
121 to remove the accessor, disconnect the spooling cable, and place it in the park position.
5. Push down on the lever on the top of the spooling mechanism ( 1 ) and slide about 10 mm towards
the center ( 2 ) to unlock the mechanism.
