3.2.1 ROLL CHART REPLACEMENT (MANUAL CASSETTE) (Cont.)
Insert the chart into the slot in the take-up spool assem-
bly, as shown. Wind approximately two turns of chart
onto the take-up spool
Whilst maintaining tension on the chart (by rotating the
take-up spool), re-insert the spool into the paper tray.
Apply light pressure to the sides of the tray and return it to
the closed position. Ensure that the platen is ‘clicked’
into place.
Tension the chart by holding the drive roller and turning
the left-hand exposed take-up flange, as shown.
The cassette can now be returned to the recorder chas-
sis, as shown, and then swung down and pushed in-
wards until it latches into position.
Ensure that the cassette drive train meshes with the
drive gear.
It is recommended that the servo pen alignment proce-
dure (section 6.3.1) is carried out to ensure that the pen
zero and span positions match the new chart.
