Excessive ribbon unwind and rewind tension will result in
variable motion and could be the cause of print quality
problems. Ensure the ribbon rewind and unwind tensions
are within specifications or adjustment of either clutch is
necessary.
Required equipment
Ribbon Clutch
Adjustment
1 Empty Ribbon Core and String
2 12mm Wrench
3 2kg Tension Gauge
4 “+” Screwdriver (JIS No.2 equivalent)
STEPS

1 Switch the printer OFF and disconnect the power
cable.
2 Open the top and front access door. Remove the
ribbon and label stock if installed.
2
3 Attach string to an empty ribbon core and place
on the Ribbon Spindle. Wind the string tightly around
the ribbon core in single layer and in clockwise direction.
Attach the end of the string to the tension guage.
1
4 Gradually lift the tension gauge, pull the string and
unwind it from the core. Once the spindle starts to
move, the gauge should indicate 500 to 700 grams of
tension for ribbon rewind, and 400 and 500 grams of
tension for ribbon unwind. Refer to picture in next page.
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.
