Manual Cartridge Removal - HP 9000 Series Service Manual

SCSI Peripherals and I/O Information
Beware also that as the firmware is fully reset at the end of the forced eject sequence, the drive will
re-instate its default setup and will lose any special features that may have been enabled by a prior
mode select command. The drive's internal trace logs will also be cleared. A forced eject will override
any Prevent Medium Removal status that may have been previously ordered by the host system. The
forced eject feature is factory configured and cannot be defeated.

Manual Cartridge Removal

If a tape cartridge becomes jammed in the tape drive, it can be extracted by performing the following
steps:
NOTE
Read these instructions fully before starting the procedure.
1. Remove the tape drive from the SPU cabinet. Refer to the Peripheral Bay removal procedure in
Chapter 7.
2. Remove the tape drive mounting brackets.
3. Remove the tape drive top cover.
4. See Figure 11-22. Insert a size 00 cross head screwdriver through the emergency eject access hole.
(Some early revisions of the mechanism have single slots in the end of the worm gear, use a flat
blade screwdriver in this case.)
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)
