Refer to Figure 4-23 and follow the procedures below to adjust the liner rewind spindle
tension.
1. Turn the printer Off (O) and remove all media and ribbon.
2. Tape the end of the 30" long Mylar tape (Zebra part # 01776) to the rewind spindle.
3. Wrap the Mylar strip around the rewind spindle in a clockwise direction.
4. Connect a 1000 gram spring scale to the Mylar strip.
5. Pull the spring scale to create the tension measurement.
6. The rotation of the rewind spindle, created by pulling on the spring scale, should be
smooth and similar to the pace of sweep of a clocks second hand. Ensure there is
no platen movement when measuring the rewind spindle tension.
7. When the rewind spindle is moving smoothly with even pull, read the tension setting
on the spring scale. The correct tension should be 700 grams (+100/–50).
8. If the tension is incorrect, use a pair of utility pliers and hold the locking nut
stationary while rotating the rewind spindle until there is easy access to the locking
screws.
9. Use a wrench driver to loosen the locking nut screws.
10. Using the utility pliers, turn the nut clockwise to increase tension, and
counterclockwise to decrease tension.
11. After achieving the correct tension, tighten the locking screws.
12. Reload the media and ribbon, and test the printer’s liner rewind function.
