FOLLOW THIS PROCEDURE
STEP 1
Turn the computer off.
STEP 2
Press STOP/EJECT to open cover, the press PLAY to
expose heads.
STEP 3
Put tape head cleaner on one side of a cotton swab.
Gently wipe the surfaces of RECORD/PLAY and erase
head (see Fig. 1).
Scrub gently. (If there is any build-up of tape oxide
particles on or around the head gap of the
RECORD/PLAY head, it is sufficient reason for
unreliable performance.)
Also clean pinch roller and other tape bearing surfaces
if tape head cleaner is suitable for this purpose (check
label).
STEP 4
Plug in demagnatizer, and activate it while it is at least one
foot away from cassette heads.
STEP 5
Slowly move demagnatizer up to RECORD/PLAY head
and around on head surface. Rate of motion should be
approximately one inch per second during this time.
STEP 6
Slowly move demagnatizer to erase head and then to all
other ferrous metal surfaces which come into proximity
with the tape.
STEP 7
Now slowly move demagnetizer away from heads. Do not
deactivate field until demagnatizer is at least two feet away
from heads.
The tape head cleaning and demagnetizing procedure is now
complete. Inspect RECORD/PLAY surface for wear. If the tape has worn a
groove on head surface more than a couple of tape thicknesses deep,
program reading performance may be poor. If so, then replacement of
tape head is indicated. (Normally few thousand hours of tape running time
have been completed before replacement is required.)
