Thermal Transfer 
Consider three important factors when selecting thermal transfer media and ribbon 
combinations: 
•   Label top coating and ribbon combinations may affect image quality; 
•   Ribbon backcoating can provide printhead protection and, depending upon the 
formula, help reduce static build-up; and, 
•   The ribbon width, when slightly wider than the media, can also guard the printhead 
against media abrasion. 
Media and Ribbon Selection 
To achieve optimum print quality and maximum printhead life, we specify the use of 
DATAMAX
 brand media. These supplies are specially formulated for use in our printers; 
use of non-Datamax supplies may affect the print quality, performance, and life of the 
printer or its components. For a current list of approved media, please contact a Media 
Representative at (407) 523-5650.
