Alternate Method - HP 3000 9x9KS Service Manual

5. Watch the tip of the screwdriver from the left hand side of the tape drive and angle the screwdriver
down into the slotted head of the worm gear.
6. Turn the screwdriver counter clockwise and watch the worm gear to make sure it is rotating.
Continue until the cartridge is unloaded (this could take approximately 1,000 turns).
7. Remove the cartridge by hand, carefully. Pay particular attention to the loop of tape outside the
cartridge, avoid snagging or tearing. (HINT, use pencil point to guide the tape over any projections.)
8. To retract the tape loop, hold the tape flap of the cartridge fully open, and use the blunt end of a
pencil to wind up the slack tape (an eraser end of a pencil is ideal)

Alternate Method

Tools required;
• electric screwdriver
• T8 or T9 Torx bit
• ball point pen (with plastic ink tube)
• scissors or knife blade
1. Remove the plastic ink tube from the ink pen.
2. Cut off approximately 50mm (2 inches) of empty ink tube from the pen.
3. Force one end of the ink tube over the torx bit (on the electric screwdriver).
4. Push the other end over the slotted end of the worm gear. This forms a flexible coupling to the
electric screwdriver.
5. Place the electric screwdriver in the unscrew (counter clockwise) position and turn on.
