Spindle Adjustment and Maintenance
There are three spindles which require periodic tension measurement and
adjustment. Measuring spindle tension should be done at least once each year
unless required more often due to high printer use. Tension should be adjusted
whenever it is not within the tolerance range associated with that spindle.
Tension Measurement Procedure
The procedure for measuring spindle tension is similar for all three spindles.
Refer to the Spindle Tension Adjustment Diagram in Figure 5.13 for specific
requirements.
1. Use adhesive tape to attach a 2" wide strip of polyester film (Part # 01776)
to the Spindle Shaft (or Core where required) as illustrated in Figure 5.13.
Wind the polyester film around the Spindle (or Core) about 5 times in the
direction indicated.
2. Slowly and evenly (2" per second) pull the strip of polyester film using the
Spring Scale. (The rotation of the spindle should be smooth and should not
cause the reading on the Spring Scale to “jump” excessively.)
3. Compare the Spring Scale reading with the load values provided in
Figure 5.13. Perform the Spindle Tension Adjustment only if the reading
is out of spec.
4. If adjustment is made, recheck the tension after running one full roll of
labels.
Spindle Tension Adjustment
Refer to the Spindle Tension Adjustment Diagram in Figure 5.13 and adjust the
Spindle Tension as follows:
1. Loosen the set screw(s) in the large Adjustment Nut at the end of the
spindle (End Cap of the Ribbon Supply Spindle).
2. Turn the Adjustment Nut inward to increase the tension or outward to
decrease the tension; then tighten the set screws.
If the Spindle Shaft turns when attempting to tighten or loosen the
Adjustment Nut, refer to Figure 5.11 and insert a 1/16" Allen wrench
through the access hole and into the set screw in the shaft collar
(105S/105Se ONLY) or into one of the slots in the plastic clutch
(160S ONLY). Hold the shaft in place with the Allen wrench while turning
the Hex nut.
3. Use adhesive tape to attach a 2" wide strip of polyester film (Part # 01776) to
the Spindle Shaft (or Core where required) as illustrated in Figure 5.13. Wind
the polyester film around the Spindle (or Core) about 5 times in the direction
indicated.
4. Slowly and evenly (2" per second) pull the strip of polyester film using the
Spring Scale. (The rotation of the spindle should be smooth and should not
cause the reading on the Spring Scale to “jump” excessively.)
5. Compare the tension reading on the Spring Scale with the appropriate load
values provided in Figure 5.13. Repeat steps 1 through 4 until the correct
tension is obtained.
