Lubricating the Knife
We recommend lubricating the knife after using 15 rolls of supply or performing 100,000
cuts.
To prevent excessive wear on the knife, regularly lubricate the knife cams. The cam are
located directly below the guiding holes.
To lubricate the knife:
1. Turn off the printer.
2. Lightly coat a long cotton swab with
multi-purpose grease.
3. Insert the cotton swab into one of the two
guiding holes until it stops on the cam.
4. Move the cotton swab up and down
several times to coat the cam with
grease.
5. Repeat steps 2 – 4 for the other cam.
6. Wipe off any excess grease from the top
cover of the knife.
7. Turn on the printer.
