Maintenance
Access to the Heads
The cassette holder door cover can be re-
moved by lifting up on the cover (as shown
in the figure) to facilitate cleaning and
maintenance of the heads and tape move-
ment path. When the cover is removed, the
cassette holder door can be closed by push-
ing in on it.
Cleaning of the Heads and Tape Path
The oxide coating from a magnetic tape
sheds off the tape as it passes over the
heads, pinch roller, capstan shaft and tape
guides. After a period of time, the build-up
of the oxide and other dirt forms a coating
on these parts which will result in a loss of
frequency response and output from the
heads as well as drop-outs in the signal from
the tape. The oxide on the pinch rollers and
capstan shaft may even cause minute
changes in tape speed and loss of smooth-
ness of tape movement. This will result in
increased wow and flutter and a decrease in
sound quality. To prevent these problems,
regular cleaning at intervals of about 8 hours
of deck usage is recommended.

Cleaning Procedure
1. Remove the cassette holder door cover.
2. Press the » (play) button to engage the
pinch rollers and raise the heads.
3. Use a cotton swab or cleaning stick
moistened in rubber cleaner (Fluid B in
the TEAC TZ-261 Kit or equivalent) to
clean the pinch rollers and capstan
shaft. Use care not to get swab caught
between pinch roller and capstan shaft.
4. Depress STOP button to separate pinch
roller and capstan shaft and lower the
heads.
5. Use a cotton swab moistened in the
Head Cleaner (Fluid A in the TEAC
TZ-261 Kit or equivalent) to clean the
heads and metal parts in the tape path.
Demagnetization Procedure
1. Remove the cassette holder door cover.
2. Turn off power to the deck.
3. Turn on the head demagnetizer (eraser)
and bring the tip of it close to the heads.
Move the tip up and down across all the
heads and other metal parts in the tape
path.
4. Slowly withdraw the demagnetizer to
about 12 inches away from the head
area,
5. Turn off the demagnetizer.
Be sure to keep all recorded tapes away
from the demagnetizer during demagnetiz-
ing.
