6.0 Service Adjustments
6.1 Stock (Web) Guide Position
The stock (web) guide is set at the factory to center the stock to the printed
image. If a slight mechanical adjustment is needed, follow these steps.
1. Locate the two plastic thumb screws under the Stock (Web) Guide mount
shaft.
2. Loosen the two screws.
3. Slide the guide in and out to the position desired.
4. Re-tighten the two screws.
6.2 Stock (Web) Guide Width Adjustments
Use the knob to move the guides until they touch the edges of the stock. Do not
pinch the web as it can damage the edges of tag stock and cause registration
errors.
6.3 Stock Feed
The Stock Feed is the assembly located in front of the knife. It requires no
pressure adjustment and will move the stock through the printer with one or
both heads closed.
The large slotted screws are not for pressure adjustment. They are used to retain
the pressure springs. They should be snug to the bottom of their travel to ensure
even pressure. If there is a tracking problem and adding back tension to the
unwind through the Virtual Control Panel will not correct the tracking problem,
loosen only one to correct the tracking is acceptable. The other screw should
remain tight to keep the feed from slipping.
If the stock will not advance through the Knife, check to be sure the knife is in the
home position (see Sect. 5.4.2, Knife Home Position Adjustment).
6.4 Knife Shear Adjustment
WARNING: Knife adjustments procedure must be followed exactly
or damage will occur.
WARNING: When adjusting, removing, or replacing the knife
assembly, you must turn off the power to the printer to avoid
personal injury.
1. Turn off the power to the printer.
