EAHG Toner
EA (Emulsion Aggreate High Gloss) toner is a relatively new type of toner with 
particles that are more spherical and uniform in size. This toner will be used for all 
Phaser 7750 Printer applications. The image below shows the EA toner particles. The 
small bumps are particles of additives that produce some of the characteristics of the 
new toner.
The image below shows some DC12 conventional toner. Like the EA toner, the small 
bumps on the outside of the toner particles are additives that are used to provide 
specific characteristics.
