 Principles of Printing
 Thermal Transfer Technology
SmartDate X60 machines use Thermal Transfer printheads, similar to the ones used in
Fax machines.
Thermal Transfer printers can also operate without ribbon by using specially treated
paper which turns black when heated. This is the way fax paper reacts.
Overprinters however, almost always use ribbon.
Both SmartDate X60 machines use Thermal transfer printheads for printing.
Each printhead has a series of heating elements (resistors) along the print line. These
printing dots are 12 per mm and are covered in a ceramic glaze for protection.
When printing, the printhead is moved out by activating a pneumatic cylinder. This
causes the printhead to press the ink ribbon against the substrate or label. The heat
from the printhead dots melt the ink and the pressure of the printhead against the
substrate transfers the ink to the substrate.
SmartDate X60 machines use Stepper Motors for Printhead motion and Ribbon feed.
