Chapter 4 - Troubleshooting and Maintaining the Printer Cleaning the Printhead Cleaning the printhead on a regular basis prolongs the life of the printhead and ensures that you maintain high print quality. You should clean the printhead with cleaning cards or a cotton swab moistened with isopropyl alcohol. Ideally, you should clean the printhead every time you load a new supply of thermal transfer ribbon. Isopropyl alcohol is a highly flammable, moderately toxic, and mildly irritating substance. Never use hard or sharp tools to peel away stuck labels or other material. The printhead is delicate and can easily be damaged. To clean the printhead 1 Open the media cover. 2 Remove the media and ribbon. 3 Pull out on the printhead lever and turn it counterclockwise to lift the printhead. 4 Use a cleaning card or a soft cotton swab moistened with isopropyl alcohol to dissolve any contamination on the line of heat-emitting dots at the front/bottom of the printhead. 5 Wait 30 seconds and carefully rub off any contamination. 6 Repeat Steps 4 and 5 if necessary. 7 Allow the printhead to dry for a minute or more before loading a new supply of media and ribbon. Cleaning the Media Compartment Regular cleaning of the printer's media compartment ensures smoother printing operation and avoids problems with media jams.
