7.2  Approved Media and Ribbon  
Media (and ribbon for thermal transfer) is an important determinant in the throughput, 
quality, and performance of the printed product. The following overview is an introduction to 
the different types of material that can be used in the printer. For complete information and 
advice regarding a specific application, consult a qualified media specialist or a Datamax 
Media Representative. Also available is an informative white paper, "A Brief Introduction to 
Media," which can be found on our website at www.datamaxcorp.com
 
 
 
Direct Thermal 
 
Consider three important factors when selecting direct thermal stock: 
 
•  The abrasiveness of the material that covers the thermal reactive layer of the paper; 
•  The amount of heat required to start the chemical reaction; and, 
•  The ability of the media to control that chemical reaction. 
 
 
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 back coating can provide printhead protection and, depending upon the formula, 
help reduce static buildup; 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.
