__ Step 4. As the 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 4 stops. The LBA is in the correct position. Note: Be sure to keep tension on the tape as the LBA is drawn into the cartridge by using a hex wrench as shown in the figure above. __ Step 5. Notice the following: a. Loader mechanism gear 8 nearest the front of the drive that actuates the cartridge loader mechanism b. Position of the rotator stub 3 . c. Front loader motor worm gear 1 . Rotating this gear allows the loader mechanism gear 8 to turn. __ Step 6. Rotate the loader motor worm gear 1 to turn the loader mechanism gear 6 counterclockwise. Continue turning until the rotator stub 3 loses contact with the lever 7 . This releases the LBA leader pin. __ Step 7. Rotate the threader motor worm gear 4 to turn the threader mechanism gear 6 counterclockwise. This moves the LBA out of the cartridge and past the read/write head. Stop this rotation when the LBA is near the tape guide roller nearest the rear of the drive 1 . 1 Figure 22. Leader Block Assembly (LBA) __ Step 8. Continue rotating the loader motor worm gear 1 until the rotate stub 3 is positioned as shown. Notice that the rotator stub 3 is nearly aligned with the cartridge loader tray guide bearing 2 . __ Step 9. Remove the cartridge from the cartridge loader tray. __ Step 10. Reassemble the drive by reversing the procedure in Step 4 in "Beginning Procedure" on page 53. __ Step 11. Refer to the appropriate procedure to install the new drive and return the failed drive. Tape Broken in Mid-tape __ Step 1. With the front of the drive facing you, pull an arm's length of tape out of the take up reel from the left side of the drive. Note: If there is less than approximately 5 cm (2 in.) of tape on the take up reel, go to "Tape Pulled from or Broken near Leader Pin" on page 56. Using Ultrium Media 57 a82ru010

Step
4.
As
the
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
±4²
stops.
The
LBA
is
in
the
correct
position.
Note:
Be
sure
to
keep
tension
on
the
tape
as
the
LBA
is
drawn
into
the
cartridge
by
using
a
hex
wrench
as
shown
in
the
figure
above.
__
Step
5.
Notice
the
following:
a.
Loader
mechanism
gear
±8²
nearest
the
front
of
the
drive
that
actuates
the
cartridge
loader
mechanism
b.
Position
of
the
rotator
stub
±3²
.
c.
Front
loader
motor
worm
gear
±1²
.
Rotating
this
gear
allows
the
loader
mechanism
gear
±8²
to
turn.
__
Step
6.
Rotate
the
loader
motor
worm
gear
±1²
to
turn
the
loader
mechanism
gear
±6²
counterclockwise.
Continue
turning
until
the
rotator
stub
±3²
loses
contact
with
the
lever
±7²
.
This
releases
the
LBA
leader
pin.
__
Step
7.
Rotate
the
threader
motor
worm
gear
±4²
to
turn
the
threader
mechanism
gear
±6²
counterclockwise.
This
moves
the
LBA
out
of
the
cartridge
and
past
the
read/write
head.
Stop
this
rotation
when
the
LBA
is
near
the
tape
guide
roller
nearest
the
rear
of
the
drive
±1²
.
__
Step
8.
Continue
rotating
the
loader
motor
worm
gear
±1²
until
the
rotate
stub
±3²
is
positioned
as
shown.
Notice
that
the
rotator
stub
±3²
is
nearly
aligned
with
the
cartridge
loader
tray
guide
bearing
±2²
.
__
Step
9.
Remove
the
cartridge
from
the
cartridge
loader
tray.
__
Step
10.
Reassemble
the
drive
by
reversing
the
procedure
in
Step
4
in
“Beginning
Procedure”
on
page
53.
__
Step
11.
Refer
to
the
appropriate
procedure
to
install
the
new
drive
and
return
the
failed
drive.
Tape
Broken
in
Mid-tape
__
Step
1.
With
the
front
of
the
drive
facing
you,
pull
an
arm’s
length
of
tape
out
of
the
take
up
reel
from
the
left
side
of
the
drive.
Note:
If
there
is
less
than
approximately
5
cm
(2
in.)
of
tape
on
the
take
up
reel,
go
to
“Tape
Pulled
from
or
Broken
near
Leader
Pin”
on
page
56.
