Technical information

1. To adjust the Backing Rewind Spindle Tension refer to Figure 5.20.
2. Turn Printer OFF and remove media and ribbon.
3. Tape the end of the Mylar strip to the Rewind Spindle.
4. Wrap the Mylar strip around the spindle in a clockwise direction.
5. Connect a 1000 gram spring scale to the Mylar strip. See Figure 5.20.
6. Pull the spring scale to create the tension measurement.
7. The rotation of the spindle, created by the spring scale should be smooth
similar to the pace of a sweep second hand on a clock. Make sure there is no
platen movement when measuring the spindle tension.
8. When the spindle is moving smoothly with even pull on the spring scale,
read the tension setting on the spring scale.
9. The correct tension should be 700 grams (+100/-50).
10. If the tension is incorrect, use a pair of utility pliers and hold the locking
nut stationary while rotating the spindle until there is easy access to the
1.5 mm Hex locking screws.
11. Using a 1.5mm Hex driver, loosen the locking nut Hex screws.
12. Using the utility pliers, turn the Hex nut clockwise to increase and
counterclockwise to decrease tension.
13. After achieving the correct tension, tighten the 1.5 mm Hex locking screws.
14. Reload media and ribbon and test the printer’s backing rewind function.
