6.0 Service Adjustments
6.1 Tape (Web) Guide Position
The tape (web) guide is set at the factory to center the tape to the printed image.
If a slight mechanical adjustment is needed, follow these steps.
1. Locate the thumb screw on the top of the Tape (Web) Guide mount plate.
2. Open the web guides to the widest position by turning the knob above the
guide clockwise.
3. Loosen the thumb screw.
4. Move the guide to the position desired.
5. Re-tighten the thumb screw.
6.2 Tape (Web) Guide Width Adjustments
Use the knob to move the guides until they touch the edges of the tape.
6.3 Auxiliary Feed
The Auxiliary Feed is the assembly located in front of the knife. It works with the
main feed to maintain proper tension of the tape as it moves through the printer
from the top print station into the Knife and Nip rollers.
If the tape 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
The Knife Assembly in your SNAP 500 printer has no field replacement
components, and basically requires no maintenance or adjustments. The only
adjustment that can be made to the knife in the field is for shear.
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.
