Cleaning the Printer Head and Roller

A dirty printer head and roller can result in poor printing quality. If you have

problems with print quality, use the following procedure to clean the printer head

and roller.

To clean the printer head and roller

1. Make sure the Label Printer is turned off.

2. Open the cassette cover.

• If a tape cartridge is loaded in the printer, remove it.

3. Use a cotton swab dipped in alcohol to clean the printer head and roller as

shown in the illustration.

• Never touch the print head or other metal objects near the head. These items

become very hot, and touching them creates the risk of burn injury.
