Manual Unload Procedure
1. The drive mechanism must be free of the assembly. DO NOT REMOVE THE
DRIVE COVERS.
2. Orient the drive on the side with the front of the drive facing towards left as shown
in Figure 6-1 below.
3. Turn the RD Thumbwheel ( Figure 6-1 on page 6-2) by hand toward the back of the
drive as far as possible. (There is no hard stop, but the wheel will begin to spring
back.) This positions the grabber into the parking position. (The grabber might
already be positioned in the parking position.)
4. Using a T-10 Torx driver, rotate the front reel motor clockwise as far as possible.
This unthreads the tape. The front reel motor will stop rotating clockwise when the
tape is completely unthreaded and the tape leader is successfully parked. If a
significant length of tape is threaded, this step could take a long time.
5. Turn the RD thumbwheel ( Figure 6-1 on page 6-2) by hand toward the front of
drive until cartridge is fully ejected. There will be some resistance as the cartridge
comes free of the magnet. This will need to be overcome to get the cartridge in the
fully ejected position.
6. Remove the cartridge by hand.
