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.
2. Using the Feed Roller knob, back the tape out of the knife.
3. Using a Phillip's head screwdriver, loosen but do not completely remove the
retaining screw on the outboard end of the knife (see Fig. 18b). Leave the
retaining screw in the assembly so you will have a place to lift the outboard
end of the assembly.
4. Place your right index finger on the head of the retaining screw and your
thumb on top of the assembly and lift up. This will remove the key that is
machined into the knife base from the groove in the mounting bracket (see
Fig. 18b).
5. Slide the knife straight out until the stripper contacts the outer support. This
will pull the rotary knife shaft from the motor drive coupler and the mounting
screw out of the clamp slot.
6. Lift the knife assembly vertically from the printer.
7. Remove the retaining screw from the used knife assembly and insert it into
the new knife assembly.
WARNING: Keep your fingers out of the knife assembly to
avoid personal injury.
