3.2.1 ROLL CHART REPLACEMENT (MANUAL CASSETTE) (Cont.)
Unscrew* the end section of the take-up spool and
remove the used chart from the remaining ‘stub’, as
shown in figure 3.2.1c. A slight rotation of the chart,
against the direction of winding may assist in the re-
moval.
Re-assemble the take-up spool.
* For recorders manufactured between January 1993
and July 1994, the end section must be pulled off,
not unscrewed. When re-assembling such cassettes,
it must be ensured that the gearwheel keyway en-
gages with the key on the inside of the stub, and that
the gearwheel is pushed fully home. Failure to
ensure this can result in faulty chart take-up action.
If necessary, remove the old chart’s cardboard spool
from the pay-off lugs
Mount a new roll of chart into the supply roll holders,
as shown.
Cut or fold the the end of the new chart into a point
Lift the plastic chart guide/paper tear-off and pass the
end of the new chart under it (figure 3.2.1e).
Ensuring that the sprocket holes do not get damaged,
pull out approximately 30 cm. of chart. Close the
chart tear-off guide, ensuring that the chart is located
squarely on the sprockets.
