STEP PROCEDURE
1. Switch the printer OFF and disconnect the power cable.
2. Raise the top access door and open the front access door. Remove the ribbon
and label stock if installed. Fig. 5-1
3. Attach string to an empty ribbon core and place on the Ribbon Unwind
Spindle. Wind the string tightly around the ribbon core in a single layer and in
in counter-clockwise direction. Attach the free end of the string to the tension
gauge. Fig. 5-3
4. Gradually lift the tension gauge, pulling the string to unwind it from the core.
Once the spindle begins to move, the gauge should indicate 450 to 550 grams
of tension. Excessive or insufficient tension must be corrected by adjusting
the Ribbon Unwind Clutch.
5. To adjust the clutch, loosen the locking screw and move the adjust nut CW for
more tension and CCW for less tension. Tighten the locking screw and repeat
steps 3 and 4 until the correct tension is achieved.
