TS3400 Tape Library Maintenance Information
7. Turn the supply reel clockwise, carefully guiding the mended portion of the tape
to wind around the hub of the supply reel located inside the cartridge. Continue
spooling tape into the cartridge until the tape is taut. The tape must remain
within the flanges of the tape guiding rollers. Ensure that you do not stretch the
tape.
8. Reassemble the drive by reversing Step 5 on page 9-47.
9. Reassemble the drive canister by reversing Step 2 on page 9-46.
10. Reinstall the drive canister into the library. Ensure that the connector on the drive
is seated properly into the connector on the cradle or shelf. See “Replacing a Tape
Drive Canister or FC 1663 Tape Drive Removal” on page 9-11.
11. Allow the drive to perform midtape recovery; messages may appear for several
minutes while this occurs. When this activity completes, the cartridge ejects
automatically.
12. Go “End of Call” on page 7-26.
Tape Tangled Along Tape Path
Use this procedure if the tape has become tangled in the tape path.
1. Carefully pull out and untangle unspooled tape until both the take-up reel and
the supply reel contain untangled tape.
Note: If you find the tape to be broken, perform one of the following
procedures:
• “Tape Spooled Off Supply Reel” on page 9-48
• “Tape Pulled from Leader Pin or Broken Near Leader Pin” on page 9-49
• “Tape Broken in Midtape” on page 9-51
2. Set the drive on its left side with the head and the tape path facing up.
3. From the bottom of the drive, locate the access hole ( in Figure 9-53 on
page 9-48) in the bottom cover. Insert a 2.5-mm offset hex wrench through the
bottom cover access hole and into the reel motor axle. Begin spooling tape back
into the cartridge by turning the hex wrench clockwise.
4. Continue spooling tape into the cartridge until the tape is taut and remains
within the flanges of the tape guiding rollers. Ensure that you do not stretch or
scratch the tape.
5. See Figure 9-54 on page 9-49. Locate the threader motor worm gear on the rear
end of the drive. Use your finger to rotate the threader motor worm gear and
slowly drive the threader mechanism gear . Rotating the threader motor worm
gear clockwise, draws the LBA into the cartridge.
6. As the tape leader block assembly (LBA) is secured in the cartridge, you should
hear the LBA retention spring clips click into place. If you do not hear the click,
continue rolling until the threader motor worm gear
stops. The LBA is in the
correct position.
7. Note the following:
• Loader mechanism gear nearest the front of the drive that actuates the
cartridge loader mechanism
• Position of the rotator stub
• Front loader motor worm gear . Rotating this gear allows the loader
mechanism gear to turn.
8. Rotate the loader motor worm gear 1 to turn the loader mechanism gear
counterclockwise. Continue turning until the rotator stub passes under the
aluminum bracket . This releases the LBA leader pin.
