6.5 TRANSPORT ADJUSTMENT
PROCEDURES
Some of the common reasons
for making transport ad -
justments
are listed below :
•
Thpe Walk
—
Thpe rides
up and down over the
heads
.
•
Improper Thpe Pack
—
Thpe does not pack smoothly
on the reel
.
•
Noisy guides
—
Thpe noise when passing through
the tape guides or the roller guides
.
•
New Headstack
—
Check the transport adjustments
when replacing the headstack with one which has
not been adjusted for this machine
.
•
Thpe Handling
—
Thpe is
not flowing smoothly
( wrinkling or curling ) over the guides
.
( Skewing )
•
Repair or Replacement of
Parts If any of the
mechanical or electrical components of the tape
transport system have been repaired
or
replaced
.
This section provides all the information required to
make
a full transport adjustment including the tape
path
,
the static head positioning
,
and the electronic
transport control system .
The mechanical tape path is critical .
Thpes recorded
on
a
mis - aligned deck will not playback properly on
any other deck
.
The tape path of the APR - 5000 is
relatively stable and rarely requires adjustment under
normal
use .
The deck has been designed so that adjustment of the
tape path is only required when the components have
been physically altered ( i
. e ,
changed or worn parts ) ,
when operated properly
,
the deck will rarely need
adjustment
.
