2E. Replacing the Cutting Knife
When a knife is dull it will no longer cut through the label at maximum pressure. You will start to see
ragged cuts or cuts that do not cut through the label material. You can attempt to increase the pressure
but you’ll probably need to replace the knife.
If a knife cuts through the liner and contacts the wear strip it may break the tip of the knife. This can be
seen under 10x magnification using a loupe or magnifying glass. If the tip is broken the knife must be
replaced.
If your knife needs replacement, follow this procedure:
1. Remove the knife holder from the carrier using the instructions from
section 2D.
2. Rotate the cap of the knife holder counterclockwise.
3. Remove the knife from the holder. You can tap the holder on a hard
surface to free the knife from the holder.
4.
Locate a new knife. Remove the molded plastic cover from the knife. The
plastic cap covers the cutting end of the knife. However, both sides are sharp! The cutting end
has an angled carbide tip. The top-end comes to a point so it can be easily
centered in the receiving divot on the knife holder cap.
5. Insert the cutting end into the knife holder.
6. Using the knife holder cover, center, the back end of the knife in the holder.
You may need to screw down the cover and reverse it several times until the
knife has been centered. Do not force the cap on the holder. The carbide tip
will break. A very slight amount of force is necessary to secure the knife holder cap.
