3.
Loop the free end of tape up over the take-up
reel in a clockwise direction, making sure
that the tape is not twisted or creased in the
process. Secure tape end to the reel by holding
the tape end with a finger through one of the
holes in the reel flange and rotate the take-
up reel clockwise, until at least one complete
turn of tape is firmly seated on the reel.
4.
Remove finger and manually continue to
turn
the take-up reel clockwise until there is suf-
flcient tape on the take-up reel to tension the
tape.
Note:
Do not manually rotate the file reel
while turning the take-up reel,
since friction provides the neces-
sary windup tension required on
the take-up reel.
5.
Make sure the tape is properly aligned on
the roller guides and
turn
the file reel slightly
to take up any remaining slack.
6.
Close the front door and press LOAD. Vac-
uum chamber(s) will activate and tape will
be tensioned and advanced to the BOT
marker.

Select the proper recording density, if appli-
cable, via the HI DEN button.
8.
Set unit select switch to desired unit
address.
9.
Check FILE PROT indicator. If tape is to be
written on, the indicator should be unlit.
10. Press ON LINE. Handler is powered and
cycled; ready for online operation.
11.
Close front glass door on the tape unit.
TAPE REWINDING
The tape unit can unwind tape in either the on-
line or oftline mode. During online operation, the
handler rewinds tape to the BOT marker under
program control.
Oftline the handler automatically rewinds tape to
the BOT marker. However, to perform such a func-
tion, the handler must be in the oftline mode.
1. Press ON LINE button. The indicator will
extinguish indicating that the handler is off-
line.
2. Press REWIND to rewind tape to the BOT
marker.
Note:
Tape rewinds at 200/250 inches per
second and continues at this rate
until light is sensed by the reel
sensor. At this point the tape
decelerates to the normal read
speed and continues to rewind at
this rate until the BOT reflective
marker is sensed.

TAPE DEMOUNTING
The following procedure should be performed
with the tape unit in the omine mode. (The ON
LINE indicator should be extinguished, indicating
that the unit is omine.)
•
If the tape is positioned at BOT:
a. Press REWIND to unwind remaining tape
from take-up reel back onto the file reel.
b. Open the front glass door on the tape unit.
c. Open the supply reel hub loading latch
and gently pull the supply reel from its
reel mount by grasping the opposite sides
ofthe reel with your fingers while pressing
firmly with the thumbs against the reel
hub.
d. Close the supply reel hub loading latch
and front glass door, unless another tape
is to be mounted.
•
If the tape is positioned past the BOT marker:
a. Press REWIND to rewind tape to the
BOT marker. Tape motion will auto-
matically stop when the BOT reflec-
tive marker is sensed.
b. Press REWIND again to unwind the
remaining tape from take-up reel back
onto the supply reel.
c. Open the front glass door on the tape unit.
d. Open the supply reel hub loading latch
and gently pull the supply reel from its
reel mount by grasping the opposite sides
of the reel with your fingers while
pressing firmly with the thumbs against
the reel hub.
e. Close the supply reel hub loading latch
and front glass door, unless another tape is
to be mounted.
OPERATOR MAINTENANCE
Operators are required to perform a limited
amount of maintenance in order to keep the tape
unites) functioning properly. This maintenance con-
sists of cleaning the following major areas:
read/write head, tape guides, capstan, tape cleaner,
vacuum chamber, erase head and tape unit sur-
faces. Cleaning should be performed once a day or as
often as required.
Prior to cleaning the unit, remove both supply
and take-up reels and then power down the unit.
CLEANING
1. Open front glass door.
2. Remove both head covers (see Figure 4-2).
3. Use a lint-free cloth moistened with Honey-
well Magnetic Tape Cleaner (Part No. 9704-
2048-001) or equivalent solution (such as
Freon "TF" solvent) and clean all exposed
surfaces of the read/write, head, tape cleaner,
erase head, and tape guides shown in Figure
4-2. Cotton swabs or a Ih-inch acid-free brush
